Epoxy Systems for Automotive Structural Components

Our EPIKOTE™ 06170 fast-cure epoxy system enables you to mass-produce lightweight carbon fiber-reinforced epoxy structural body parts in cycle times as short as one minute. Features include:

Developed for industrial scale RTM/LCM processing
Low viscosity
Very fast cure
Easy demolding with HELOXY™ Additive TRAC 06805 release agent
Suitable for chassis, semi-structural parts and body exterior
Up to 70% weight savings compared with steel

We also offer a specialty epoxy resin system, EPIKOTE Resin TRAC 06605/EPIKURE™ Curing Agent TRAC 06608, for styrene-free sheet molding compound (SMC) manufacturing of structural and semi-structural parts. Hexion’s SMC epoxy system, when combined with glass and carbon fibers, results in parts with superior mechanical properties to those made with standard unsaturated polyester (UP) or vinyl ester (VE) SMC resin systems.
