West System 205 “Fast” Hardener

WEST SYSTEM 205 Fast Hardener® is a medium-viscosity epoxy curing agent. It is used at lower temperatures to produce a rapid cure that develops its physical properties quickly at room temperature.

When mixed with WEST SYSTEM 105 Epoxy Resin® in a five-part resin to one-part hardener ratio, the cured resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties.
