Product Description
EL-337 is an improved, health-safe, two component, filled, non-staining, high temp epoxy laminating system specifically developed for room temp hardening (B Stage) with high temp properties for high temp tooling applications. EL-337 has excellent handling properties and fabric wet-out to produce a void free tool with high dimensional stability. EL-337 can be used in the construction of large or small tools, as well as production parts. El-337 can also be used with ADTECH High Temp Surface Coats ES-219 and ES-229. Tools made with EL-337 can be used at continuous temperature of 160°C/320°F, and intermittent temperatures up to 191°C/375°F. While EL-337 will gel at room temp, it must be post-cured to achieve ultimate strength. The system contains no MDA or VCHD. Typical applications include: vacuum form molds, prototype injection molds, high temp bonding fixtures, spray metal molds, compression molds, high temp laminated molds and parts to be used in high temp applications.
