Custom thermoset resin formulation for specialty composite applications
In-house development of custom epoxy, phenolic, and other thermoset resin systems tailored to specific application requirements — flame retardancy, heat resistance, chemical resistance, fast cure, or special surface appearance — integrated with CFRP/GFRP molding at production scale.
Problem solved
Standard prepreg systems from major suppliers (Toray, Hexcel) are optimized for aerospace structural properties but do not address application-specific constraints like flame/smoke/toxicity for public transit, chemical resistance for semiconductor wet processes, or fast-cure cycles for high-volume consumer-electronics production. Customers requiring specialty resin properties must either develop them in-house or work with multiple suppliers.
Application contexts
- Flame-retardant CFRP for railway/aerospace interior panels
- Chemical-resistant composites for semiconductor wet-process equipment
- Fast-cure resin for high-volume consumer electronics housings (10,000+/month)
- High-temperature BMI systems for aircraft engine-adjacent components
- UV-resistant coatings for outdoor wind turbine blades and automotive exterior parts
Technical principle
SRI's materials lab formulates and tests thermoset resin systems (epoxy, phenolic, BMI, specialty urethanes) to meet defined performance targets: glass transition temperature (Tg), flame retardancy (UL94 / railway / aerospace standards), chemical resistance, cure cycle speed, viscosity for specific molding processes, and surface quality for visible/aesthetic parts. Formulations are then transferred to production with qualified cure cycles on SRI's autoclave, press, or filament-winding equipment.
Typical use cases
- Semiconductor equipment OEM needing CFRP process chambers with resistance to specific chemical etchants at elevated temperature
- Railway rolling stock manufacturer requiring CFRP interior panels meeting EN 45545 flame/smoke/toxicity standards
- Consumer electronics brand seeking a fast-cycle CFRP laptop housing with specific surface appearance and UL94 V-0 rating
Partnership route
How global engineering teams typically engage this asset.
Helpful to include: Can you formulate a resin system targeting Tg >200°C with chemical resistance to specific solvents? · What flame-retardancy standards has your custom resin achieved (UL94, EN 45545, FAR 25.853)? · What is the minimum development quantity for a custom resin formulation project? · Can you share a case study of a custom resin developed for a non-aerospace application?
Have specific parameters to run against this asset?
