Headquartered in Hamburg, Germany, WindPro is a leading R&D and manufacturer of epoxy matrix resins for onshore and offshore wind turbine blades in Europe, with 28 years of expertise in high-end wind power composite materials. Its products supply wind turbine OEMs including Siemens Wind Power and Enercon. All raw materials comply with EU REACH regulation, GL wind turbine material certification and low-VOC environmental standards.
The company previously maintained annual fixed procurement of 186 tons of original Evonik EPODIL748 C12-C14 alkyl glycidyl ether (AGE), which was fully applied to epoxy infusion systems for wind blade core materials. WindPro is a mid-to-high-end industrial customer prioritizing product performance over low unit prices, with strict formulation customization requirements and tight control over impurity indicators – distinct from low-end trading buyers who purchase standard domestic AGE in bulk and only compete on factory ex-factory prices.
Due to maintenance shutdowns at local European production facilities, Evonik’s lead time extended to 110 days, and import raw material prices surged by 32%, WindPro’s R&D division launched a domestic raw material substitution program. Its core requirement was to move beyond generic off-the-shelf C12-C14 AGE and develop a tailor-made modified grade. While the original imported grade delivered satisfactory low-temperature toughness, high dosage levels led to excessive curing shrinkage of the resin system, resulting in microcracks on blades under low-temperature high-altitude operating conditions.
The client required customized modified C12-C14 alkyl glycidyl ether that retains the original viscosity reduction performance, improves the elongation at break of cured products, lowers resin curing shrinkage rate, and imposes strict limits on three key indicators: total chlorine, free epichlorohydrin (ECH) and color.
WindPro independently contacted three domestic conventional AGE manufacturers, yet all factories could only mass-produce standard domestic off-the-shelf AGE (APHA ≤30, hydrolyzable chlorine ≤0.02eq/100g, epoxy value 0.30~0.33eq/100g) and lacked capabilities for formulation modification, iterative lab trials and exclusive customized mass production. Their existing processes failed to meet the client’s modified indicators for enhanced toughness and reduced shrinkage; all lab trial formulations resulted in resin shrinkage cracks and substandard low-temperature impact resistance, halting the customization project. WindPro then entrusted HiSiaddi to oversee the full process including formulation customization, process optimization, pilot scale-up and mass production launch.
1. Color: APHA ≤8 (generic commercial products generally range 20~30)
2. Precisely locked epoxy value: 0.34~0.35eq/100g; viscosity: 5~7mPa·s @25℃
3. Hydrolyzable chlorine ≤0.008eq/100g, inorganic chlorine ≤30mg/kg, free ECH ≤5ppm
4. When added to wind power matrix epoxy resin at 12% dosage: cured product elongation at break increased by ≥18%, linear curing shrinkage reduced to below 0.35%, no cracking after -40℃ thermal cycling tests
1.
Domestic manufacturers only produce standardized mass goods with no R&D capacity for customized modification Domestic AGE producers operate fixed continuous production lines with predetermined feed ratios of C12-C14 fatty alcohol and epichlorohydrin, manufacturing generic grades with fixed formulations and rectification processes. They are unwilling to reconstruct reaction kettles and rectification towers for individual clients. Their technical teams can only guarantee national standard parameters and lack understanding of modification logic matching wind power epoxy formulations, making it impossible to adjust molecular structures to boost toughness and cut shrinkage.

3.
Disconnection between lab trials and pilot production, no support for gradient sample iteration The client required multiple gradient batches of samples for formulation screening, yet conventional factories set a minimum batch order of 25kg. This drove high sampling costs and long iteration cycles, exceeding the client’s R&D budget and preventing completion of more than 5 groups of variable lab tests.

5.
Precision impurity control fails to meet EU wind power certification thresholds Excessive total chlorine and trace residues in generic products cannot pass Germany GL wind power material incoming inspections, disqualifying the material for mass production of offshore wind blades even if formulation performance meets requirements.

HiSiaddi assembled a special task force consisting of fine chemical formulation engineers, synthetic process specialists and EU compliance engineers, partnering with a domestic specialized AGE modification manufacturer to roll out customized development in three phases: lab sample R&D → 5kg pilot test → 50-ton trial production.
1. Adjust raw material carbon chain ratio: Modify the conventional C12/C14 fatty alcohol feed ratio from 6:4 to 4.5:5.5 to extend flexible alkyl chains and boost post-curing resin toughness. Introduce a small amount of ethylene oxide block modification during synthesis to optimize ether bond structures and fundamentally reduce curing shrinkage of epoxy systems at the molecular level.
2. Optimize synthetic refining process: Replace single-stage rectification with dual-tower negative-pressure molecular distillation to sequentially strip residual epichlorohydrin, short-chain heteroalcohols and chlorine-containing impurities, strictly controlling color and total chlorine indicators.
3. Prepare 6 groups of gradient samples (500g per group) and ship them to German laboratories for parallel formulation testing, accompanied by bilingual Chinese-English COA and full EU-compliant SGS test reports. WindPro’s R&D team conducted matching resin tests on each sample group.
The 4th formulation among the six sample groups fully satisfied all client indicators: APHA=6, epoxy value 0.346eq/100g, viscosity 6.2mPa·s, hydrolyzable chlorine 0.006eq/100g. When added to matrix resin at 12% dosage, elongation at break rose by 21.3% and curing shrinkage fell to 0.32%, with zero cracking after 50 cycles of -40℃ high-low temperature alternating tests. HiSiaddi coordinated factory modification of a 50L experimental reactor to complete the finalized 5kg pilot test, with all full-process process parameters (reaction temperature, pH, rectification vacuum level) archived and fixed.
1. HiSiaddi coordinated short-term technical renovation of a 2000L mass production line at the factory, adjusting feed ratios and rectification operating conditions, and isolating the production line separately to avoid cross-contamination with generic grades.
2. Manufactured a total of 50 tons of customized AGE-WP in two batches. Each batch was sampled independently for full-scope third-party SGS testing against German wind power raw material standards, with batch indicator fluctuations controlled within ±2%.
3. Customized packaging: 200kg galvanized baked enamel iron drums printed with German-English bilingual CLP labels, marked with exclusive grade name, CAS No.68609-97-2 and REACH registration number, complying with EU warehousing and ocean shipping regulations.
The 50 tons of customized AGE-WP were shipped by sea to a bonded warehouse in Hamburg, Germany. WindPro deployed the material for small-batch mass production of offshore wind turbine blades, achieving smooth blade infusion without air bubbles and no microcracks on finished products post low-temperature production. Final products successfully passed third-party Germany GL wind power material certification, with performance matching original Evonik EPODIL748. The client’s comprehensive raw material procurement cost dropped by 26.8%, and delivery lead time was shortened from 110 days to 42 days.
WindPro reduced its annual procurement volume from Evonik and signed an exclusive annual 186-ton long-term supply agreement with HiSiaddi for custom AGE-WP. The contract stipulates the formulation of this grade shall remain exclusive and the factory shall not sell identical modified products to external parties. It also commits HiSiaddi to provide free formulation fine-tuning and sample trial support annually for the client’s new resin iteration projects.
1.
Shortcomings of domestic raw material manufacturers: Prioritizing standardized off-the-shelf goods over high-end customized R&D Most domestic C12-C14 AGE manufacturers focus on mass production of generic national standard products with fixed production lines, unwilling to invest in technical renovation to accommodate niche customized orders. Their products suit low-end bulk spot trading but fail to meet the exclusive formulation customization demands of mid-to-high-end overseas new material enterprises.

3.
Core demands of mid-to-high-end clients: Exclusive grade customization + full-chain technical support Unlike low-end buyers purchasing off-the-shelf goods directly, European wind power, high-end electronics and pharmaceutical mid-to-high-end clients require raw materials deeply integrated with their own end-product formulations, demanding tailor-made molecular structures and physical & chemical indicators, alongside full-chain services including iterative sample preparation and compliance documentation – services that ordinary manufacturers cannot independently deliver.
