Purchaser: LUXCOAT GmbH, Germany A German specialized listed enterprise manufacturing high-end OEM automotive UV topcoats, high-filler titanium matte coatings, and thick-film insulating UV resins, supplying chassis component coating for Mercedes-Benz and BMW, as well as new energy battery insulating coatings across Europe. The client previously purchased 75 tons of original BASF IGM Omnirad 819 annually, complying with EU REACH, RoHS 2.0, low precipitation, low heavy metal, and high-temperature yellowing resistance high-end raw material access standards. Faced with price hikes at European chemical manufacturers, extended shipping lead times exceeding 60 days for original products, the client launched domestic Chinese substitution selection for 819.
The client independently contacted five mainstream domestic 819 manufacturers (Jiuri New Materials, Shinwell New Materials, Yangfan New Materials, Nanjing Wali, Shandong Jiadejia) for quotations and sample testing, yet encountered common industry pain points: all manufacturers only promote their own grades, fail to objectively disclose competitive advantages of peer products, and refuse horizontal comparison of grade performance differences for clients. Unable to distinguish performance gaps between general industrial-grade and high-end optical-grade 819, the client tested samples from five manufacturers and encountered inconsistent curing instability, high-temperature precipitation, and coating yellowing issues. After 35 days of R&D testing without identifying suitable grades, the client fully entrusted HiSiaddi with neutral full-brand evaluation and grade screening.
Practical challenges encountered by the client after direct communication with five leading manufacturers:
1. Jiuri New Materials prioritizes its fiber-grade 819-HF, highlighting global leading mass production scale for optical fiber coatings and high purity, while concealing Shinwell New Materials’ advantages in yellowing resistance and pigment compatibility for optical coatings, only introducing its own product application scenarios;
2. Shinwell New Materials prioritizes its high-end optical grade S-819, emphasizing its multi-stage negative pressure precision rectification process and low byproduct advantages, while avoiding discussion of Jiuri’s strengths in large-batch stable mass production and long-wave absorption stability;
3. Yangfan New Materials only promotes its general industrial-grade FY-819, focusing on cost-effectiveness and large-batch ink supply advantages without contrasting performance gaps and strengths of high-end grades from other manufacturers;
4. Nanjing Wali VL-819 and Shandong Jiadejia JADEWIN 819 target ordinary plastic coating markets, only promoting sufficient spot inventory and fast delivery without objective comparison of parameter gaps relative to high-end grades from listed leading manufacturers.
All manufacturers abide by industry norms against malicious denigration of competitors, yet prioritize amplifying their own product highlights and avoiding peer advantages to secure orders. The client lacks classification awareness for domestic 819 grades, divided into three tiers: general ink industrial grade, mid-tier plastic grade, and high-end optical/automotive coating grade. Identically named 819 products differ by dozens of times in impurity and phosphorus residue content across grades, making it impossible for clients to distinguish performance tiers solely by product names, resulting in high blind sample testing costs and lengthy testing cycles.
Leveraging domestic photoinitiator industrial chain databases and third-party laboratory testing resources, HiSiaddi sorted all 819 models from five manufacturers (Jiuri New Materials, Shinwell New Materials, Yangfan New Materials, Wali Chemical, Jiadejia New Materials), and decomposed advantages and disadvantages item by item matching the client’s automotive color paint and high-titanium filled thick coating application scenarios, compiling bilingual Chinese-English comparative evaluation tables.
Available models: General Grade 819-G, High-Purity Fiber Grade 819-HF ✅ Advantages: 819-HF is optimized for communication optical fiber coatings with main content ≥99.85%, triphenylphosphine oxide byproducts ≤10ppm, stable long-wave UV absorption, minimal batch fluctuations in mass production, maximum global annual output of 3,000 tons with industry-leading large-batch supply stability, and low chloride ion content compatible with high-end hydrolysis-resistant systems. ❌ Disadvantages: 819-HF formulas are biased toward transparent fiber films, exhibiting mediocre compatibility in high-titanium high-filler color paint systems with occasional localized uneven curing at low dosages; general grade 819-G contains excessive byproducts and heavy metal residues above 30ppm, only suitable for low-end inks.
Available models: General Industrial 819-T, High-End Optical S-819, Modified Compound S-819-Plus ✅ Advantages: S-819 series adopts multi-stage negative pressure precision rectification processes optimized for molecular dispersion in high-titanium color paints with excellent pigment wettability and outstanding yellowing resistance, byproducts ≤7ppm, specially adapted for automotive colored thick coatings; S-819-Plus incorporates trace synergistic compound components for further enhanced deep curing performance of thick films. ❌ Disadvantages: Limited production capacity for high-end grades, longer mass order scheduling cycles than Jiuri fiber grades, slightly higher unit price compared to Jiuri’s fiber-grade products.
Available model: Single general industrial grade FY-819 (full product line only offers this grade) ✅ Advantages: Abundant spot inventory, lowest unit price, compatible with wood printing inks and ordinary plastic clear coats, flexible small-batch delivery. ❌ Disadvantages: No high-end refined grades; triphenylphosphine oxide byproducts ≥280ppm with elevated heavy metal content, prone to high-temperature white haze precipitation, failing EU automotive coating environmental access standards, only suitable for low-end civil coatings.
✅ Advantages: Flexible small-batch packaging, fast sample delivery for small trial orders. ❌ Disadvantages: Only conventional rectification processes without optical-grade purification production lines, performance indicators comparable to Yangfan FY-819, unable to meet stringent low-precipitation requirements.
✅ Advantages: Convenient 1kg small packaging for sample testing. ❌ Disadvantages: Targeting domestic low-end ink markets, high color values with severe high-temperature yellowing (ΔE＞2.5), failing European high-end automotive coating indicators.
Client products: High-titanium white automotive chassis UV topcoats (35~50μm thick films), new energy battery insulating UV coatings, requiring low precipitation, low yellowing, high pigment compatibility, and stable batch performance. General industrial-grade products from Yangfan, Wali, and Jiadejia were eliminated, leaving two mid-to-high-end manufacturers (Shinwell New Materials, Jiuri New Materials) with three segmented grades for gradient sampling testing:
1. S-819 (Standard Optical Grade): Primary mass production material for conventional white automotive topcoats, balancing yellowing resistance and pigment compatibility;
2. S-819-Plus (Modified High-End Grade): For ultra-thick 50μm battery insulating coatings, reinforced deep curing formula to resolve incomplete thick-film curing.
Spare grade dedicated to transparent insulating clear coat formulas, leveraging Jiuri’s ultra-high batch stability for separate procurement matching the client’s transparent coating formulations alongside Shinwell’s two grades.
1. Tiered lab trials: HiSiaddi coordinated supply of 5kg samples from both manufacturers, synchronized SGS EU compliance testing and formulation evaluation at the client’s German laboratory. Shinwell S-819/S-819-Plus delivered zero precipitation and compliant yellowing performance in high-titanium systems; Jiuri 819-HF exhibited transparent coating performance matching original imported IGM materials.
2. Pilot mass production: 500kg pilot batches ordered for each grade, full-process production line testing at the client’s German facility, three consecutive batches of finished coatings passing Mercedes-Benz OEM incoming material inspections.
3. Annual order split: Total annual 75-ton procurement split as follows: 52 tons of Shinwell S-819 (primary white topcoat material), 13 tons of S-819-Plus (thick-film insulating material), 10 tons of Jiuri 819-HF (transparent clear coat), with a signed annual framework supply agreement.
1. Comprehensive procurement cost of three domestic grades reduced by 27.3% versus original BASF 819, sea freight lead time shortened from 60 days to 22~28 days;
2. Finished coating yield maintained at the 99.4% level achieved with imported raw materials, successfully passing long-term supplier audits for Mercedes-Benz and BMW OEMs;
3. The client’s subsequent new matte colored automotive coating project fully entrusted HiSiaddi with brand grade optimization and selection coordination for the two manufacturers.
1. Domestic identically named 819 covers multiple performance tiers and segmented grades. Manufacturers’ sales-oriented promotion prevents objective horizontal comparison of peer product strengths and weaknesses, forming the largest selection barrier for overseas high-end clients;
2. Core Value of HiSiaddi: Neutral third-party perspective, horizontal parameter decomposition across all brands, and targeted tiered selection aligned with end-use application scenarios, avoiding mass production scrap losses for clients from misselected low-end industrial materials;
3. Selection Logic of European and American Mid-to-High-End Clients: Prioritize formulation operating condition matching, environmental compliance, and batch stability, with unit price as a secondary consideration. Neutral professional grade screening services form the core competitive advantage for long-term client binding.
