SikaBiresin® L337 is a two component, filled, non-staining epoxy laminating system that provides room temperature hardening (B Stage) and is designed for high temperature laminating and tooling applications. SikaBiresin® L337 has excellent handling properties and fabric wet-out to produce a void free tool with high dimensional stability. Tools made with SikaBiresin® L337 can be used at continuous temperatures of 230°F (110°C) and up to a 250°F (121°C) intermittent use maximum. While SikaBiresin® L337 will gel at room temperature, it must be post-cured to achieve ultimate strength.
