Purchaser: AC-Paint GmbH, Bavaria, Germany This enterprise specializes in production of OEM topcoats for German vehicle OEMs, modified plastic coatings for bumpers and anti-corrosion clear coats for aluminum parts of new energy vehicles. Its products support original factory coating for mid-to-high-end models under BMW and Volkswagen, complying with EU REACH, VOC and automotive coating TL standards. Annual stable UV 292 procurement volume reaches 52 tons, with long-term procurement of original BASF Tinuvin 292 hindered amine products in prior years.
Driven by surging local European chemical raw material prices and extended import lead time to 90 days, the client launched a localization substitution selection project for domestic mid-to-high-end UV 292 grades to replace imported raw materials. Having no prior experience purchasing domestic additives, the client was unfamiliar with mainstream domestic UV 292 brands, performance differences between various models and compatible systems. It separately contacted five leading domestic UV 292 manufacturers: Lianlong, Fujian Disheng, Beijing Tiangang, Yantai Xinxiu and Shandong Hengqiao for sample consultation.
Sales staff from all five manufacturers operate compliantly without belittling competitors, yet constrained by corporate sales orientation, they only elaborate on their own product strengths while avoiding peer brands’ advantages and failing to objectively benchmark competitor parameters:
1. Lianlong focuses on large-scale mass production and automotive coating certification advantages without mentioning Disheng’s low-temperature modification or Tiangang’s low free amine strengths.
2. Disheng prioritizes its solvent compatibility and low volatility features without acknowledging Lianlong’s mature formula matching and abundant downstream vehicle coating application cases.
3. Tiangang, Xinxiu and Hengqiao all highlight single unique strengths of their own products while refusing objective horizontal comparison of competitors’ applicable scenarios, drawbacks and matching formulas.
The client received 7 batches of samples from five manufacturers with no horizontal data reference. Independent lab testing revealed partial samples prone to low-temperature precipitation, partial hazing upon mixing with high-acid-value PU clear coats, and partial substandard weathering aging performance. Sample testing consumed one and a half months without locking a suitable grade, stalling the selection process. The client entrusted foreign trade service provider HiSiaddi to conduct neutral full-brand evaluation and precise grade selection.
1. No crystallization or stratification after static standing at -12°C for 72 hours;
2. Free amine ≤0.08%, no whitening upon compatibility with high-acid-value acrylic PU resins;
3. Xenon lamp aging ΔE ≤1.0 after 3,800 hours;
4. Low volatility with no oily distillate generated during 120°C baking finish;
5. Full SDS and REACH documentation compliant for export to Germany.
HiSiaddi’s additive engineers collected mainstream off-the-shelf grades from all five brands for unified parallel lab testing, and objectively sorted out strengths and limitations of product lines of Lianlong, Disheng, Tiangang, Xinxiu and Hengqiao combined with the client’s automotive clear coat formula system, disclosing each brand’s merits and limitations without brand bias.
1.
Lianlong (RIASORB®): Leading domestic additive manufacturer with two core grades: Standard UV 292 & Automotive Special Modified UV 292-L ✅ Advantages: Strong mass production stability with minor physical and chemical fluctuations across batches, mass-adopted in OEM coatings of multiple domestic vehicle manufacturers, complete REACH filings, and mature synergistic weathering data when blended with UV1130. ❌ Drawbacks: Standard grade delivers average low-temperature performance with turbidity easily triggered at -5°C; customized modified grades carry higher unit prices and longer lead times for small-batch orders.
2.
3.
Fujian Disheng (DSunsorb®): Specialized refined additive enterprise with Standard UV 292 & Low-Temperature Modified DS-292LT as core grades ✅ Advantages: Modified grades feature outstanding optimized low-temperature formulas without crystallization at -15°C, excellent solvent compatibility in solvent-borne automotive clear coats, and well-controlled free amine content. ❌ Drawbacks: Smaller mass production scale than Lianlong for standard grades, lower production priority for large-batch orders, and slightly weaker weathering resistance of standard grades versus Lianlong’s automotive special modified grades.
4.
5.
Beijing Tiangang: Time-honored hindered amine manufacturer focusing on single core grade: Refined High-Purity UV 292 ✅ Advantages: Industry-leading low free amine content, excellent compatibility with high-acid resins and low impurity levels. ❌ Drawbacks: No segmented low-temperature modified grades, prone to precipitation under low-temperature storage, single product line only suitable for coating production lines with ambient storage.
6.
7.
Yantai Xinxiu: Leading Shandong additive manufacturer focusing on standard universal UV 292 single product ✅ Advantages: Outstanding cost performance and high compatibility with general industrial coatings. ❌ Drawbacks: Limited production capacity for high-purity modified grades, high thermal volatility unsuitable for high-temperature baking high-end automotive coatings.
8.
9.
Shandong Hengqiao: Standard mass-production route for mid-to-low-end universal UV 292 ✅ Advantages: Ample spot inventory and low pricing. ❌ Drawbacks: Few refining processes leading to high residual small molecules, failing client internal control standards for low-temperature performance and weathering resistance required for high-end automotive coatings.

Combined with the client’s three application scenarios: high-temperature baking finish, low-temperature warehousing and high-acid-value automotive PU clear coats, HiSiaddi eliminated Xinxiu, Hengqiao and Tiangang from the five brands and finalized two mid-to-high-end leading manufacturers: Lianlong and Fujian Disheng, with three precisely matched segmented grades for gradient sample delivery.
1. Lianlong RIASORB UV292-L (Automotive Special Modified Grade) Matching Scenario: Client’s primary two-component polyurethane automotive transparent clear coat, fully matching performance of original BASF indicators with optimal mass production stability for long-term large-scale stock preparation.
2. Disheng DS-292LT (Dedicated Low-Temperature Modified Grade) Matching Scenario: Raw materials for low-temperature production lines of the client’s Nordic branch factory, resolving crystal pipeline blockage issues in winter low-temperature storage tanks.
3. Disheng Standard DS-UV292 (High-Purity Refined Universal Grade) Matching Scenario: Economical color coating product line of the client, offering cost advantages over modified grades while balancing weathering resistance and mixing stability.
1. Lab Small-Batch Testing: HiSiaddi assisted the client in unified panel preparation at German labs. All three grades passed four strict tests: static exposure at -12°C, resin compatibility, 3,800-hour xenon lamp aging and high-temperature baking. Among them, Lianlong UV292-L matches original BASF performance, Disheng DS-292LT perfectly addresses low-temperature crystallization pain points, and Disheng standard grade meets cost reduction demands for color coatings.
2. Client Workshop Pilot Mass Production: 200kg of each grade was purchased for pilot trials, deployed separately across three production lines for clear coats, low-temperature production and color coatings with continuous manufacturing. No coating haze, spray gun blockage or coating film yellowing rejection occurred, and all pilot finished products passed incoming quality inspection of vehicle OEMs.
The client split its 52-ton annual framework order by consumption volume of three production lines:
1. Lianlong UV292-L: 32 tons (Annual raw material for primary transparent clear coats, shipped in monthly batches);
2. Disheng DS-292LT: 12 tons (Dedicated for Nordic low-temperature production facilities);
3. Disheng DS-UV292: 8 tons (Supporting mass-production color coatings). HiSiaddi simultaneously assisted both manufacturers in completing REACH filings required for German import, German-English bilingual GHS-SDS and batch SVHC test reports. Goods were shipped in three separate batches from Shanghai Port to Bavaria, Germany with zero customs clearance obstacles.
1. Client Procurement Cost Reduction: Comprehensive procurement costs of the three domestic grades dropped by 32% compared to original BASF products, with overall lead time shortened from 90 days to 35 days.
2. Full-Category Additive Custody & Selection: All subsequent domestic selection of UV absorbers, antioxidants and other light stabilizers was entrusted to HiSiaddi for neutral brand evaluation, eliminating independent contact with individual manufacturers by the client.
3. In-Depth Brand Collaboration: Drawing on application data from this high-end German vehicle coating client, Lianlong and Disheng synchronously optimized parameter specifications of corresponding grades. With HiSiaddi’s support, two European automotive coating clients in Austria and Switzerland were newly developed.
1. Sales-oriented constraints of domestic UV 292 manufacturers lead to exclusive promotion of their own products and refusal of objective horizontal comparison of competitors’ strengths—this constitutes the core difficulty for high-end overseas clients conducting independent domestic additive selection.
2. Core Value of HiSiaddi: Based on end-user formulation demands and decoupled from interests of single manufacturers, HiSiaddi conducts neutral horizontal multi-brand parameter evaluation beyond single-brand sales thinking to accurately screen optimal grades matching client working conditions, filling information blind spots of high-end overseas clients regarding domestic additives.
3. Mid-to-high-end European and American coating clients prioritize not only low pricing during grade selection but also matching segmented models, batch stability and supporting technical consultation. Neutral third-party selection services represent core value unavailable to ordinary factory sales staff.
