MEDIUM VISCOSITY EPOXY HARDENER
Back to
Hardener page
Product Description:
Accelerated aliphatic amine adduct. Fast curing, medium viscosity hardener designed for impact resistance and mold cycling speed. 100:20 by weight mix for highest HDT. May be mixed by volume, 5:1 for highest HDT, with increasing flexibility as more hardener is used. No VOC’s, 100% solids.
Product Uses:
Press-molded parts such as snow-skis, water-skis, snowboards, etc. |
