I. Client Profile

The cooperating client is COMPOSITE TECH DE, a high-end composite materials group headquartered in Munich, Germany. It specializes in R&D and production of aerospace-grade glass fiber-reinforced composites, high-end electronic encapsulants and structural bonding adhesives for new energy vehicles, supplying top brands including Airbus, Siemens and BMW. It complies with German DIN standards, EU REACH regulations and aerospace-grade material access requirements, representing a high-end client with strict zero-tolerance quality standards.

The client purchases 45 tons of dual-amino KH-792 silane coupling agent annually, previously sourcing German Wacker imported products. Facing cost pressures, the client planned to shift procurement to China. However, the client had limited understanding of China’s KH-792 market. After liaising with five domestic factories, it discovered each manufacturer only promoted its own products while avoiding peer comparisons, making comprehensive objective brand data inaccessible and creating a procurement dilemma: fearing substandard low-cost low-end products while lacking channels to screen mid-to-high-end grades matching imported quality. The client therefore entrusted HiSiaddi with full-process services covering brand research, cross-model comparison, targeted product recommendation and sample validation.

II. Core Client Pain Points & Selection Dilemmas

(1) Core Selection Requirements (Clear Mid-to-High-End Positioning)

· Quality benchmarked against Wacker GENIOSIL® GF 91: main active content ≥98.5%, chroma (Pt-Co) ≤15, free methanol ≤0.3%

· Compatible with aerospace glass fiber epoxy systems, robust hydrolysis resistance with no abnormalities after 1,200-hour salt spray testing

· High batch consistency: main content deviation ≤0.2%, complete COA and traceability reports provided per batch

· Full compliance with EU REACH & RoHS standards with multilingual SDS and TDS documents available

(2) Market Research Pain Points

1. Fragmented brand information: The client only knew a handful of major manufacturers including Chenguang New Materials and Dongyue Organosilicon, lacking systematic understanding of technical capabilities, quality positioning and mainstream models of each brand.

2. Biased factory communication: The five contacted manufacturers only highlighted their own product strengths (e.g. "99% purity", "mass production capacity") without objective recognition of peer advantages, even evading key parameter comparisons and preventing horizontal evaluation by the client.

3. Confusion between high and low-end grades: The market is flooded with low-cost low-end grades (main content 95%–97%, chroma ≥20), with some manufacturers misrepresenting inferior products as premium grades, leaving the client without reliable identification methods and risking failure to meet aerospace-grade application standards post-procurement.

4. Ambiguous model matching: Each brand offers multiple segmented KH-792 grades (general grade, high-purity grade, modified grade). The client lacked clarity on performance differences and applicable scenarios across models, hindering precise matching with its proprietary formulas.

III. HiSiaddi Objective Brand Analysis & Targeted Recommendations

Drawing on ten years of organosilicon industry resources, HiSiaddi screened five mainstream mid-to-high-end domestic KH-792 brands and delivered unbiased horizontal comparisons covering technical strength, mainstream models, core parameters, performance advantages and applicable scenarios, providing transparent decision-making references without favoritism or disparagement.

· Shortcomings: Relatively high pricing; salt spray resistance weaker than Chenguang and Liansil

1. Guangdong Dixin Chemical (South China Mid-Tier Brand, Cost-Effective General-Grade Supplier)

· Technical strength: Medium-scale manufacturer focused on general-grade products with stable quality that fails to meet high-end standards.

· Mainstream models: KH-792 (General Grade)

· Core parameters: Main content 97%–98%, chroma 18–22, free methanol ≤0.5%

· Core strengths: Low pricing with fast 3–5 day lead times, suitable for mid-to-low-end coatings and rubber applications

· Shortcomings: Poor hydrolysis and salt spray resistance with inconsistent batch stability, unable to satisfy aerospace-grade requirements

(2) Targeted Mid-to-High-End Brand & Model Recommendations

Aligning with the client’s core aerospace-grade composite material requirements for hydrolysis resistance, low chroma and exceptional batch consistency, HiSiaddi eliminated the mid-tier cost-effective brand (Dixin) and shortlisted two optimal mid-to-high-end brands and three matching models from the remaining four premium manufacturers with clear justifications and applicable scenarios:

1. Primary Recommended Brand: Jiangxi Chenguang New Materials (2 Models)

· Recommended Model 1: KH-792 (High-Purity Grade) Applicable Scenarios: Glass fiber epoxy composite materials, electronic encapsulants Recommendation Justification: Main content ≥98.8%, chroma ≤12, batch deviation ≤0.15%, fully matching Wacker GF 91 quality benchmarks and meeting aerospace-grade access standards.

· Recommended Model 2: KH-792A (Hydrolysis-Resistant Modified Grade) Applicable Scenarios: Marine engineering anti-corrosion coatings, high-humidity environment composite materials Recommendation Justification: Hydrolysis resistance improved by 30% with no peeling after 1,500-hour salt spray testing, resolving high-humidity working condition pain points for the client.

1. Alternative Recommended Brand: Nanjing Liansil Chemical (1 Model)

· Recommended Model: USi-D1301M (Hydrolysis-Resistant Modified Grade) Applicable Scenarios: Outdoor new energy structural component bonding in Germany, low-temperature construction systems Recommendation Justification: Main content ≥98.6%, chroma ≤13, unimpeded feeding at -15°C with uniform curing for outdoor construction; 8% cost savings versus Chenguang with equivalent performance.

IV. Sample Validation & Final Order Confirmation

1. Sample Submission & Performance Testing HiSiaddi coordinated free 5kg sample provision for the three recommended models from Chenguang and Liansil, alongside COA, SDS, TDS documents and REACH compliance test reports. The client conducted internal testing within its glass fiber epoxy system:

· Chenguang KH-792 (High-Purity Grade): Coating adhesion, salt spray resistance and mechanical performance fully met specifications, matching Wacker GF 91 performance exactly.

· Chenguang KH-792A: Optimal stability under high-humidity conditions with zero surface defects after 1,500-hour salt spray testing.

· Liansil USi-D1301M: Smooth feeding at -15°C with uniform curing, satisfying outdoor construction requirements.

1. Final Procurement Decision Synthesizing quality compatibility, pricing and lead time factors, the client finalized its procurement plan:

· Primary Purchase: Jiangxi Chenguang KH-792 (High-Purity Grade), 40 tons annual volume (89% of total demand) for core aerospace-grade composite materials.

· Supplementary Purchase: 3 tons Chenguang KH-792A + 2 tons Liansil USi-D1301M for high-humidity working conditions and low-temperature outdoor products respectively.

1. Transaction Guarantees HiSiaddi assisted the client in signing a tripartite quality agreement stipulating 100% batch qualification, unconditional return & exchange for substandard quality and compensation clauses for delivery delays. Third-party test reports are issued prior to every shipment to ensure full quality control.

V. Case Summary

For overseas mid-to-high-end clients purchasing KH-792, core demands center on transparent brand comparisons, precise model matching and verifiable premium quality rather than purely low pricing. Most domestic manufacturers prioritize profit motives and avoid objective peer comparisons, leaving clients confused during product selection.

Leveraging an impartial industry stance, comprehensive brand resources and professional technical judgment, HiSiaddi broke down information barriers by delivering cross-brand horizontal comparisons of five manufacturers and accurately recommending two mid-to-high-end brands plus three compatible models. This satisfied the client’s aerospace-grade quality requirements while cutting procurement costs by 18% versus original Wacker imported supplies, securing long-term stable cooperation. This case once again validates HiSiaddi’s professional value in premium chemical raw material selection, technical matching and full-spectrum supply chain services.
