I. Manufacturers of Coatings & Inks (Anti-Corrosion Coatings, Waterborne Industrial Paints, Epoxy Topcoats, Ink Primers)

(I) Core Pain Points

Poor coating adhesion with easy peeling, degraded salt spray resistance under high temperature & humidity, rapid hydrolysis causing gelation in waterborne systems, pinholes & craters on coating surfaces, unstable adhesion from batch-to-batch activity fluctuations

1. Insufficient amino activity of ordinary KH-792 leads to weak substrate adhesion and easy coating peeling off Low-end products feature low bifunctional amino components, only forming single-bond linkage with weak anchoring power on metal, glass and stone substrates. Cross-cut adhesion tests fail, and coatings peel off easily under hot-humid environments.

2. Poor salt spray & hot-humid resistance causing blistering and rust on anti-corrosion coatings in short term Ordinary products deliver low crosslink density with abundant micro-pores in formed films, allowing water vapor and salt spray ions to penetrate and break through coatings, resulting in unqualified salt spray test results for industrial anti-corrosion primers and high rework rates of finished workpieces.

3. Excessively fast hydrolysis in waterborne coating systems leads to gelation, thickening and scrapping of stored coatings KH-792 features extremely strong hydrolysis activity; low-end products lack stabilizing systems. After mixing with waterborne emulsions, excessive premature hydrolysis triggers sharp molecular weight increase, local gelation and agglomeration in storage tanks, directly scrapping entire batches of coatings.

4. High small-molecule residues cause pinholes and bubbles during high-temperature coating baking Crude products contain excessive methanol residues and low-molecular impurities, which volatilize rapidly during thermal curing and damage coating compactness, leaving pinholes, craters and bubbles on finished surfaces and drastically lowering yield rates.

5. Batch-to-batch amino content fluctuations lead to inconsistent adhesion under fixed formulation ratios Large deviations in active components between batches cause fluctuating adhesion performance under fixed addition dosages, failing standardized mass production.

(II) Targeted Solutions

1. High-purity bifunctional amino activity locking technology preserves complete dual functional groups for stable anchoring, drastically boosting coating adhesion to metal, glass and concrete substrates with zero peeling in cross-cut tests.

2. High crosslink density film-forming modification improves coating compactness to block water vapor and salt spray penetration, elevating salt spray and hot-humid resistance to meet heavy industrial anti-corrosion standards.

3. Slow-release stabilization technology for waterborne systems controls hydrolysis rate to avoid premature crosslinking and gelation, adapting to waterborne industrial paints and waterborne epoxy systems with stable storage without thickening or agglomeration.

4. Deep removal of methanol and small-molecule impurities delivers low volatility and minimal pore formation, yielding smooth, compact coatings free of pinholes or bubbles after high-temperature curing with top-tier surface quality.

5. Precise batch-to-batch amino content control guarantees consistent activity, allowing buyers to fix addition ratios and processes for zero fluctuation in mass production quality.

II. Manufacturers of Epoxy Adhesives & Sealants (Structural Adhesives, Two-Component Epoxy AB Glues, Polyurethane Sealants, Metal Bonding Adhesives)

(I) Core Pain Points

Insufficient adhesive bonding strength, debonding after thermal cycling, brittle cured adhesives, system delamination and failure during storage, poor compatibility with epoxy systems

1. Weak interfacial anchoring force leads to low shear strength for metal/glass bonding Impure active components in ordinary KH-792 cannot form stable covalent bonds between inorganic substrates and organic adhesive layers, resulting in easy interfacial peeling under stress and unqualified structural adhesive bonding strength.

2. Easy debonding and separation after alternating high-low temperature thermal cycles Low-end products deliver poor crosslink toughness, failing to release interfacial stress under temperature variations and generating micro-delamination after repeated thermal expansion & contraction, shortening service life of outdoor products.

3. Excessive impurities trigger over-crosslinking, yielding brittle cured adhesives with poor impact resistance Excessive acid-base impurities in raw materials accelerate localized over-curing, reducing adhesive toughness and making products prone to cracking and edge chipping under stress.

4. Delamination and transparency loss after compounding with epoxy and curing agents Poor compatibility of ordinary products with epoxy resins and curing agents causes slight turbidity and delamination post-blending, impairing appearance of high-end transparent adhesives.

5. Short shelf life of finished products with obvious bonding performance attenuation after 3 months Poor raw material stability triggers slow self-polymerization during long-term storage, depleting active functional groups and drastically reducing adhesive strength of downstream finished products in later storage stages.

(II) Targeted Solutions

1. Fully preserved high-activity bifunctional amino structure strengthens organic-inorganic interfacial bonding, significantly elevating shear and peel strength to meet high-strength structural bonding requirements.

2. Flexible crosslink modification technology improves temperature cycling resistance of interfaces, eliminating debonding and separation for outdoor and equipment structural bonding applications.

3. Deep refining and impurity removal delivers neutral stable systems with uniform crosslinking during curing, yielding tough, impact-resistant adhesives free of cracking with superior mechanical performance of finished products.

4. High-transparency compatible formulation delivers high miscibility with epoxy, polyurethane and polyurea systems, producing clear, transparent blends without turbidity or precipitation.

5. Anti-self-polymerization stabilization treatment preserves raw material activity during long-term storage, ensuring consistent performance throughout the full shelf life of downstream adhesive finished products.

III. Manufacturers of Glass Fiber & Composite Materials (Glass Fiber Sizing Agents, Fiberglass Reinforced Plastics, Epoxy Composites, Insulating Materials)

Poor glass fiber bundle penetration, low interlayer peeling strength of composites, high water absorption with degraded weather resistance, sharp strength loss under high-temperature molding, excessive fuzz and filament breakage

1. Uneven glass fiber surface coating and slow resin penetration speed Poor wetting and spreading performance of low-end KH-792 leads to incomplete single-filament coating, hindering resin penetration and generating dry filaments, white spots and void defects in composite materials.

2. Weak interlayer bonding force and low interlayer peeling strength Low silane coupling bridging efficiency results in loose bonding between resin and glass fiber interfaces, easy interlayer separation and peeling under stress and unqualified product strength.

3. High water absorption of finished products with severe mechanical attenuation under humid environments Large interfacial pores allow water vapor intrusion, softening fiberglass composite materials and reducing strength & deformation resistance under humid conditions.

4. Rapid activity loss under high-temperature compression molding Poor thermal resistance of ordinary products triggers premature decomposition at molding temperatures of 120–150°C, drastically reducing reinforcement effects and overall rigidity of finished products.

5. Unstable sizing agent batches increase glass fiber fuzz and filament breakage rates Fluctuations in raw material viscosity and activity destabilize sizing agent formulations, impairing glass fiber bundling performance, raising fuzz generation and breakage rates during production with high material loss.

(II) Targeted Solutions

1. Super wetting and spreading system delivers uniform complete coating of single glass filaments, accelerating resin penetration and eliminating dry filament, white spot and void defects.

2. High-strength bifunctional amino bridging structure drastically improves interlayer peeling strength, producing integrated composite materials resistant to delamination and cracking.

3. Dense hydrophobic interfacial modification reduces water absorption of composite materials, maintaining stable performance without softening or deformation for superior weather resistance under humid environments.

4. High-temperature resistant stabilized formulation resists decomposition and activity loss at 150°C compression molding, delivering stable strength under high-temperature forming for high-end composite manufacturing.

5. Dual-index locking of viscosity and activity unifies sizing performance across batches, improving glass fiber bundling performance with reduced fuzz, filament breakage and production loss.

IV. Compound Additive OEM Manufacturers (Silane Compound Solutions, Primers, Adhesion Promoters, Export OEM Additives)

(I) Core Pain Points

Unstable batch activity disrupting compounding ratios, turbidity and precipitation after compounding, self-polymerization thickening during storage, discoloration under high-temperature ocean shipping, antagonism and failure when mixed with additives

1. Batch-to-batch amino content fluctuations destabilize finished compound product performance As the core active source of compound formulations, inconsistent activity of KH-792 causes fluctuating performance of adhesion promoters and primer products under fixed recipes.

2. Turbidity and precipitation after compounding with alcohol and solvent additives Excessive impurities and unstable polarity in low-end products impair compatibility with solvents and curing additives, destabilizing blended systems and triggering turbidity.

3. Self-polymerization thickening during long-term storage leading to viscosity rise and scrapping Crude silanes without stabilizing systems undergo slow intermolecular crosslinking during storage, with continuous viscosity increase eventually causing full-barrel gelation and scrapping.

4. Oxidative discoloration under high-temperature enclosed ocean shipping yellowing transparent OEM finished products Amino groups oxidize and discolor under high-temperature sealed transport conditions, disqualifying materials for manufacturing high-end transparent primers and transparent additive finished products.

5. Antagonism and activity loss when compounded with acidic additives and curing agents Unneutralized acid-base impurities trigger rapid reaction and precipitation after blending, completely eliminating coupling and adhesion-promoting functions.

(II) Targeted Solutions

1. Precisely fixed amino activity with minimal batch deviation eliminates formulation re-adjustment for mature compound recipes, delivering uniform mass production finished product performance.

2. High-purity compatible system adapts to alcohol, ester and solvent systems, yielding clear, transparent blends free of precipitation or turbidity after compounding.

3. Anti-self-polymerization stabilizers maintain constant viscosity during long-term ambient storage without thickening or gelation for extended shelf life.

4. Anti-oxidation decolorization technology resists discoloration and yellowing under high-temperature ocean shipping, suitable for high-end transparent export OEM products.

5. Neutral buffer purification treatment delivers compatibility with most acidic and neutral additives without blending antagonism or activity loss.

V. Cross-Border Chemical Raw Material Distributors (Bulk Drum Repackaging, Overseas Warehousing, Regional Distribution)

(I) Core Pain Points

Adulterated low-cost raw materials, falsely labeled active activity, moisture absorption and hydrolysis failure during ocean shipping, incomplete compliance documents causing customs detention, delamination and uneven concentration in bulk drums

1. Low-cost market goods adulterated with water or ordinary silanes posing as high-purity KH-792 Unscrupulous merchants blend KH-550, solvents and water to cut costs, resulting in insufficient bifunctional amino activity, unqualified downstream adhesion and weather resistance and mass customer complaints & returns.

2. Falsely labeled active ingredient content drastically reducing actual activity upon arrival Low-cost goods feature insufficient labeled active content, failing to deliver required bonding and reinforcement effects under standard addition dosages.

3. High susceptibility to moisture absorption and hydrolysis during humid ocean shipping leading to full-barrel failure Ordinary products lack sealed stabilization treatment; moisture penetrates drums during ocean transport triggering premature hydrolysis and self-polymerization, raising viscosity and scrapping entire batches upon arrival.

4. Missing REACH, SDS, CLP and hydrolysis safety reports causing customs detention in Europe and America Silanes fall under regulated chemicals; incomplete documents block customs clearance and legal local sales.

5. Long-term static storage delamination in bulk drums with uneven top-bottom concentration destabilizing repackaged batch quality Heterogeneous raw materials feature dilute upper layers and concentrated lower layers, producing inconsistent performance across repackaged small barrels and severely damaging channel reputation.

I. Core Considerations Throughout the Whole Process of Sourcing KH-792 Silane Coupling Agent from China

Commercial KH-792 is normally a colorless to pale yellow transparent viscous liquid; water-soluble grades feature relatively low viscosity. Its active ingredient content, amine value, methanol content, water content, refractive index, hydrolysis stability, pH value and storage stability are determined by silane monomer quality, amination synthesis process, rectification for alcohol removal and dehydration stabilization procedures. As an organoamine silicon compound, it has certain alkalinity, volatility and irritation. It is classified as a common corrosive liquid in most countries and regulated as an irritant chemical in some regions. Cross-border logistics must comply with corresponding hazardous/non-hazardous chemical rules. Meanwhile, overseas markets impose strict controls on REACH, SVHC, VOC, methanol residues, heavy metals and water solubility standards. Chemical registration, environmental emission and raw material standards for coatings/adhesives vary across countries. Purchasing decisions should not be based solely on unit price and appearance; downstream formulations, processing techniques and local regulations must be comprehensively evaluated.

(I) Compliance Document Verification: Align with Global Regulations to Ensure Smooth Customs Clearance and Legal Production

With dual attributes as fine chemical raw material and alkaline irritant liquid, KH-792 is subject to supervision covering chemical registration, corrosive/irritant classification, SVHC screening, VOC emissions, toxic residue limits and water environmental protection. Complete compliance documents are prerequisites for cross-border customs clearance, legal production and penalty avoidance.

1.

Specialized Testing & Certifications Matched to End Applications For goods exported to the EU, North America, Japan, South Korea and other mainstream markets for high-end coatings, structural adhesives, engineering plastics and export composites, suppliers must provide REACH registration documents, SVHC screening reports, alongside test data on heavy metals, methanol residues, VOC volatiles and polycyclic aromatic hydrocarbons. For waterborne coatings, daily chemical auxiliaries and indoor decorative materials, additional reports on odor grade, water solubility, biological toxicity and aquatic ecological safety are required. For adhesives/coatings auxiliary materials in food/drinking water contact scenarios, food contact safety certifications, substance migration tests and toxicology reports are mandatory. General industrial raw materials shall be supplied with waste gas and wastewater pollutant emission test documents in accordance with local industrial chemical specifications.

2.

3.

Full Set of Documents for Cross-border Transportation & Customs Clearance Classification standards differ by territory: liquid KH-792 is categorized as corrosive/irritant liquid in most regions. Suppliers shall provide multi-language SDS safety data sheets and chemical classification identification reports. If classified as hazardous goods locally, UN numbers and hazardous goods packaging certificates shall be provided simultaneously. For regions regulating it as general chemical goods, SDS and classification reports suffice for customs inspection. Standard customs clearance documents include certificates of origin, batch-by-batch COA quality inspection reports and production traceability documents. High-end export products shall be supplemented with gas chromatography component analysis, methanol content and hydrolysis stability test reports.

4.

5.

Supplier Qualification Screening Prioritize original manufacturers with export qualifications for corresponding categories and long-term overseas supply experience. Verify the traceability of third-party testing institutions and their reports. Excessive methanol residues, unqualified harmful impurities or non-compliant classification/packaging may lead to cargo detention, production line shutdown, finished product recalls and environmental & safety penalties. Qualification review must be completed in advance.

6.

(II) Raw Materials & Production Processes: Lock Rectification Procedures to Stabilize Composition and Service Performance

The active ingredient content, amine value, free methanol, water content, refractive index, hydrolysis stability and color of KH-792 are determined by upstream silane monomer and amine raw material quality, as well as amination synthesis, multi-stage vacuum rectification, methanol removal, dehydration conditioning, stabilization treatment and precision filtration processes. These indicators also distinguish high-purity refined grade, general industrial grade, high hydrolysis stability grade and water-soluble grade.

1.

Upstream Raw Material Inspection Premium products adopt high-purity γ-chloropropyltrimethoxysilane and refined ethylenediamine as primary raw materials, featuring low monomer impurities and by-products. The finished products deliver high main component purity, stable amine value, low free methanol and low-molecular amine volatiles, with mild odor, low VOC and excellent hydrolysis resistance, resisting delamination and failure during long-term use. Low-end products use crude industrial raw materials or recycled by-products, resulting in high residual monomers, free methanol and low-molecular amines. They emit pungent odor, cause excessive VOC in workshops, trigger pinholes in coatings, abnormal curing of adhesives and reduced interfacial strength of composites, making them unsuitable for high-end coatings and export adhesive products. For high-purity grades, buyers may request raw material purity certificates from suppliers.

2.

3.

Confirmation of Core Production Processes Mainstream production route: silane monomer + ethylenediamine liquid-phase amination synthesis → multi-stage vacuum rectification → vacuum methanol removal → dehydration conditioning → stabilization treatment → precision filtration.

4.

· High-purity refined grade: Deep rectification plus vacuum alcohol & water removal to maximize elimination of free methanol, residual monomers and low-molecular amines. It features pure composition, long shelf life and outstanding hydrolysis stability, targeting high-end coatings, structural adhesives and food-contact auxiliary materials.

· General industrial grade: Standard rectification balancing performance and cost, suitable for ordinary adhesives, conventional glass fiber treatment and general filler modification.

· High hydrolysis stability grade: Optimized molecular stabilization system and buffer formula to enhance stability in water-containing systems and high-humidity environments, extending pot life.

· Water-soluble grade: Formulated with dedicated solubilizing components for arbitrary miscibility with water, exclusively for waterborne coatings and water-based treatment agent systems. Formal production lines adopt closed continuous reaction equipment with full temperature control and air isolation to prevent material oxidation and discoloration, leading to minimal batch-to-batch fluctuations in active content, amine value, methanol and water content. High-end specifications utilize independent production lines to avoid cross-contamination; suppliers shall not mislabel industrial grade as high-purity refined grade.

1. Quality Control & Production Capacity Assessment KH-792 is mass-produced via continuous processes with stable supply capacity. Buyers are advised to request multi-batch COAs, gas chromatography component analysis, hydrolysis stability and thermal stability test data, focusing on fluctuation ranges of active ingredient content, total amine value, free methanol, water content, refractive index, density, pH and color. For long-term cooperation, lock raw material grades and process parameters to guarantee formulation consistency across batches. Prioritize original manufacturers with complete synthesis, amination, rectification and alcohol removal production lines. Traders blending batches of varying purity will directly impair coating adhesion, adhesive curing and composite material strength. Also request stability data under alternating high-low temperature, long-term static storage and different humidity/pH environments to adapt to ocean shipping and storage across global regions.

(III) Grade, Specification & Formulation Matching: Select Based on Purity & Working Conditions to Avoid Parameter Mismatch

Commercial KH-792 is categorized by purity grade, functional characteristics and dissolution system. Different parameters deliver distinct reactivity, hydrolysis performance, volatile content and system compatibility. Improper selection causes insufficient adhesion, abnormal curing, system delamination, excessive odor/VOC and hydrolysis failure.

1. Purity Grade Classification

· High-purity refined grade: High main component content, ultra-low methanol and impurities, precise amine value. Applied in high-end coatings, structural adhesives, food/drinking water contact auxiliaries and export engineering plastics.

· General industrial grade: Cost-effective for ordinary adhesives, conventional glass fiber treatment and general filler modification. Sign nominal values and allowable fluctuation ranges of active ingredient content, total amine value, maximum free methanol limit, water content and refractive index in contracts.

1. Functional & System Segmentation

· Conventional oil-soluble grade: Suitable for solvent-based coatings, anhydrous treatment agents and non-aqueous adhesive systems.

· Water-soluble grade: Miscible with water at any ratio, exclusively for waterborne coatings, water-based surface treatment fluids and eco-friendly water-based formulations.

· High hydrolysis stability grade: Improved water and humidity resistance for high-humidity working conditions, long-term immersion products and outdoor weather-resistant materials. Different model grades cannot be interchanged.

1. Physical Properties & Packaging Specifications Qualified products are uniform transparent viscous liquid without turbidity, delamination, precipitation or visible impurities. In accordance with local classification standards, 200L brand-new corrosion-resistant plastic drums or galvanized iron drums are adopted; hazardous goods packaging drums are used in territories classifying it as hazardous chemical, and standard industrial liquid drums for general grades. Small-batch samples use compliant small packaging. Confirm minimum order quantity and production cycle in advance for special specifications such as ultra-low methanol, high hydrolysis stability and customized water-soluble formulations. Send samples for compatibility tests, adhesion verification, curing inspection and hydrolysis stability testing before bulk order placement.

(IV) Commercial Terms & Full-Link Cost Calculation: Calculate Total Expenses Based on Chemical Properties

KH-792 is categorized as hazardous or general chemical goods by territory, with packaging, commodity inspection and international logistics costs varying by classification. Significant price gaps exist between different purity and functional grades. Cost calculation cannot rely solely on unit price; full-link measurement covering trade modes and chemical classification is required.

1. Quotation Modes

· FOB China Port: Quotation covers goods, domestic transportation, dedicated packaging and domestic commodity inspection fees. International logistics, insurance, destination port customs clearance and inspection fees are borne by buyers. For territories classifying it as hazardous goods, domestic hazardous packaging and declaration fees are included. Ideal for large coating groups, adhesive manufacturers and composite material factories with dedicated freight forwarders and annual bulk orders, delivering optimal overall costs.

· CIF Destination Port: Quotation covers full ocean freight, insurance, port charges and document processing, with suppliers managing the entire process for simplified operation. Suitable for first-time cooperation, small and medium batch purchases and regional chemical distributors. Request volume tiered pricing and annual long-term price locks to hedge price fluctuations of upstream silane monomer and amine raw materials.

1.

Payment, Lead Time & Dispute Resolution Clauses International trade commonly adopts T/T or irrevocable L/C payment. Hazardous chemical goods involve more complex document procedures, implemented per agreed timelines between both parties. General industrial standard grades are in stock with short lead times; customized grades including high-purity refined, high hydrolysis stability and water-soluble types require reserved cycles for rectification & alcohol removal, modified blending, special testing and packaging inspection. Define dispute judgment criteria in contracts: substandard active ingredient content/amine value, excessive methanol/water, turbid/delaminated liquid, abnormal compatibility/curing and misrepresented product grades. Specify re-inspection, return, exchange and replenishment processes. Clarify that slight color deepening and elevated viscosity under low temperature during storage and transportation are normal physical phenomena to divide liabilities clearly.

2.

3.

Minimum Order Quantity & Storage Agreements Standard orders are per full drum with no split-drum delivery. The product is alkaline and volatile, requiring storage in cool, ventilated warehouses isolated from acids, heat and fire sources. High temperature accelerates volatilization and material oxidation discoloration; high humidity impairs hydrolysis stability. Agree on free domestic storage duration and prohibit long-term cargo storage in open-air or high-temperature port areas; acidic and alkaline materials must be stored separately.

4.

(V) Packaging, Storage, Transportation & Logistics Control: Adopt Protective Standards per Local Classification

Liquid KH-792 is regulated as corrosive/irritant hazardous chemical or general industrial chemical across territories. Core storage and transportation risks include drum leakage, acid-base contact reactions, oxidative discoloration under high temperature, volatile accumulation and viscosity rise at low temperature. All operations shall comply with IMDG, IATA and local chemical storage & transportation codes, focusing on leakage prevention, temperature control, acid-base isolation and ventilated storage.

1.

Packaging Standards For territories classifying it as hazardous goods: Brand-new compliant corrosion-resistant hazardous drums with double sealing gaskets and reinforced lids, printed with UN numbers and corrosion/irritation warning labels. Each drum undergoes leakage testing before delivery. For general chemical territories: Thickened corrosion-resistant plastic drums or galvanized iron drums with tight sealing. Outer packaging shall be uniformly marked: alkaline liquid, keep away from acids, store in cool dark places, ventilated storage. Packaging strength shall withstand ocean stacking and long-distance bumpy transportation.

2.

3.

Transportation & Environmental Control Large-tonnage goods prioritize ocean shipping; hazardous grades are loaded in hazardous cargo holds while general grades use standard chemical holds. Maintain overall transport temperature between 10–30°C. Avoid high-temperature cabin spaces for tropical summer routes; temperature-controlled containers are available for high-latitude winter regions to prevent excessive viscosity at low temperature affecting unloading. Air freight shall be declared and operated in compliance with local classification rules. Minimize transshipment frequency; intermediate stations store goods separately by classification with acid and oxidant materials segregated for loading and storage. Purchase cargo insurance for high-purity and customized export orders.

4.

5.

Storage, Transportation & On-Site Usage Reminders Store goods separately in ventilated warehouses upon arrival at destination port with classified segregation. Operators shall wear alkali-resistant protective equipment. Increased viscosity at low temperature is a normal physical property; slowly restore to room temperature instead of open flame or high-temperature heating. Tightly seal drum lids after each use to reduce volatilization and moisture absorption. Maintain ventilation in operation areas to avoid volatile accumulation.

6.

(VI) Technical Support & After-Sales Service: Assist Formulation Tuning to Solve Adhesion, Curing, Hydrolysis and Compliance Issues

Amine value, methanol content, water content and hydrolysis stability of KH-792 directly affect coating adhesion, adhesive curing speed, filler modification effect and system pot life.

Deliver solutions for insufficient adhesion, abnormal curing, system delamination, short pot life, excessive odor/VOC and hydrolysis failure, while interpreting local REACH, SVHC, hazardous goods, food contact and aquatic environmental protection regulations for target export countries.

2.

3.

Post-Arrival Re-inspection Coordination Sampling shall be implemented in accordance with local chemical sampling standards. Buyers may independently test basic indicators including content, amine value, water content, appearance and refractive index, or entrust third-party institutions to conduct full-component, methanol content and hydrolysis stability full-item testing. Follow agreed procedures for handling products with indicators inconsistent with contract specifications.

4.

5.

Document Assistance & Regulation Interpretation Provide multi-language SDS, classification identification reports, hazardous packaging/UN documents (if required), REACH/food contact/toxicity test reports and translated documents as needed.
