The client is ELECTRO-SIL GmbH, a high-end electronic materials enterprise based in Germany specializing in semiconductor packaging, OLED photo-crosslinkers and raw materials for premium electronic coatings. It serves leading European electronics manufacturers with extremely stringent technical thresholds and strong customized material requirements, representing a typical top-tier mid-to-high-end European industrial client.
Core demand: Custom ultra-high-purity Vinyltriisopropenoxysilane (CAS:15332-99-7) for OLED display photo-crosslinkers with an annual demand of 15 tons. Key specifications are as follows:
· Purity ≥99.5% (conventional industrial grade only reaches 98%)
· Water content ≤50ppm, free acid ≤10ppm
· Low metal impurities (Na/K/Fe ≤1ppm)
· Zero solvent residue, fully compliant with EU REACH & SVHC regulations
· Custom 10kg high-purity nitrogen-sealed packaging for dust-free workshop feeding
The client previously sourced customized-grade products from Shin-Etsu Japan for a long time, which came with drawbacks including high unit price (380 CNY/kg), long lead time (60 days) and high minimum order quantity (50 tons). The client planned to shift procurement to Chinese suppliers yet was rejected by 4 domestic manufacturers in sequence due to failure to meet purity standards, excessive metal impurities and inability to deliver customized packaging. Finally, the client entrusted HiSiaddi with full responsibility for customized development and mass production implementation.
OLED-grade silane requires ultra-high purity and ultra-low metal impurities. Most domestic manufacturers only produce industrial-grade products (98% purity) without rectification purification and oxygen-free synthesis processes, making stable production of 99.5% high-purity products unachievable.
The client requires 10kg nitrogen-sealed packaging, dust-free workshop filling and English traceable batch reports, with small single-batch output (1–2 tons). Manufacturers regard such orders as cumbersome and low-margin, refusing to invest in equipment renovation.
Full EU REACH registration, SVHC 241-item testing, ICP metal impurity reports and English SDS/TDS are mandatory, yet most manufacturers can only provide ordinary Chinese reports that fail to meet traceability standards of the high-end electronics sector.
Impurity excess in electronic materials will lead to scrapped OLED panels with losses exceeding millions per batch. The client demands full-process verification (lab trial → pilot trial → mass production) with shared risk bearing, which manufacturers refuse due to reluctance to cover R&D failure costs.
HiSiaddi set up a special task force consisting of organosilicon synthesis engineers, high-purity purification specialists, electronic-grade quality control personnel and compliance specialists, collaborating with 2 manufacturers equipped with high-purity silane R&D capabilities to launch a customized project covering 7 days of lab trials, 15 days of pilot trials and 30 days of mass production, comprehensively resolving technical, production, packaging and compliance challenges.
· Process optimization: Revised synthetic route adopting oxygen-free addition reaction + secondary high-efficiency rectification to replace traditional one-step synthesis, lifting purity from 98% to 99.7%, exceeding the client’s 99.5% requirement.
· Impurity management: Electronic-grade raw materials (metal impurities ≤0.5ppm) are deployed; reactors and pipelines adopt electrolytically polished 316L stainless steel with full nitrogen blanketing. Metal impurities (Na/K/Fe) are controlled ≤0.8ppm, water content ≤30ppm and free acid ≤8ppm.
· Lab trial verification: Three rounds of lab trials each yielding 5kg samples passed full-index testing conducted by third-party laboratory EUROFINS. Samples delivered to the client’s laboratory delivered crosslinking efficiency and yellowing stability equivalent to Shin-Etsu Japan’s products.
· Flexible production scheduling: A dedicated high-purity silane production line was allocated at the cooperative factory to prioritize small-batch orders (1–2 tons per batch), cutting lead time to 25 days.
· Dust-free filling: A Class 10,000 dust-free workshop was renovated with nitrogen-sealed filling equipment to isolate air and impurities throughout operations. Products are packed in 10kg high-purity aluminum foil bags filled with nitrogen and protected by stainless steel drums, matching feeding requirements of the client’s dust-free workshop.
· Exclusive batch management: English traceable reports are provided for each batch, recording raw material batch numbers, synthesis parameters, rectification curves, test data and operator information for full lifecycle traceability.
· Testing & certification: EUROFINS, an EU-recognized third-party laboratory, issued full test reports covering purity, metal impurities, water content, SVHC and REACH compliance with dual CNAS/EUROFINS official seals.
· Technical documents: 16 types of English-language documents including SDS, TDS and COC (Certificate of Conformity) as well as batch traceability reports were compiled, complying with EU GHS/CLP and IATF 16949 traceability standards for the electronics industry.
· Compliance endorsement: REACH registration certificates, SVHC non-detection declarations and RoHS compliance statements were supplied to support the client’s high-end project audits.
· Phased delivery: 5kg lab trial samples → 50kg pilot batches → 1-ton mass production batches, with each subsequent phase initiated only after the client confirms satisfactory testing results of the prior phase.
· Quality guarantee: A quality indemnity agreement was signed stipulating HiSiaddi shall bear full compensation for production losses incurred by the client due to substandard purity or excessive impurities of supplied products, eliminating the client’s risk concerns.
1.
One-time qualification of customized products with superior performance Mass-produced products maintain stable purity of 99.6%–99.7%, metal impurities ≤0.8ppm and water content ≤30ppm. The OLED crosslinking efficiency is 3% higher than Shin-Etsu Japan’s products with no yellowing or precipitation. The products passed the client’s full performance testing and EU compliance audit in one attempt and were officially applied to mass production of premium European OLED panels.

Cost reduction & supply stability Compared with original Shin-Etsu Japan supplies, procurement costs decreased by 42% (from 380 CNY/kg to 220 CNY/kg) and lead time shortened from 60 days to 25 days. Dual backup manufacturing plants guarantee stable annual supply of 15 tons with zero risk of supply disruption.

Long-term exclusive strategic cooperation Highly recognizing HiSiaddi’s technical R&D capacity, customized service awareness and risk-sharing mechanism, the client terminated cooperation with the Japanese supplier and signed a 3-year exclusive annual supply contract of 15 tons. All subsequent customized demands for semiconductor packaging silanes and high-end coating modified silanes were exclusively entrusted to HiSiaddi, establishing HiSiaddi as its sole Chinese partner for high-end customized silanes.

When overseas mid-to-high-end electronic material clients source ultra-high-purity customized silanes, core challenges include high technical thresholds, special customized specifications, rigorous compliance and traceability requirements, as well as severe trial-and-error risks. Ordinary domestic manufacturers are "incapable, unwilling and afraid" to undertake such orders. Leveraging integrated professional technical capabilities, flexible production coordination, full-chain compliance services and risk-sharing cooperation models, HiSiaddi connects the entire industrial chain covering R&D, lab trials, pilot trials, mass production, packaging, compliance and delivery to precisely meet ultra-stringent client standards. This solution not only helps clients cut costs, boost efficiency and stabilize supply, but also secures long-term trust from top-tier European electronic clients through robust customized services, empowering Chinese high-end fine chemical customization capabilities to enter the global mid-to-high-end market.
