EPOXY LAMINATING SYSTEM
WHITE, ROOM TEMPERATURE, HARDENER CHOICE SIKABIRESIN L302-1
DESCRIPTION
SikaBiresin
L302 is a white room temperature laminating system with excellent handling characteristics,
low viscosity and high strength. Its low toxicity makes it ideal for laminated tooling and production
applications. SikaBiresin
L302 exhibits excellent dimensional stability, high mechanical strength and
excellent cloth penetration (wet-out) without run- out. Use SikaBiresin
L302 with epoxy surface coat
systems ES-218 or TCC- 352 for high early strength properties. SikaBiresin
L302 Resin is available with
the following hardener options: SikaBiresin
L302-1 Hardener (see work life details listed below). Typical
applications include: prototypes, keller models, master models, patterns and core boxes, checking
fixtures, production parts, trim fixtures, holding fixtures, duplications and router and drill fixtures.
