Epoxy Hardener, Fast 205-C 0.94Gal
205 Fast Hardener is medium-viscosity epoxy curing agent for use with WEST SYSTEM 105 Resin. 205 Fast Hardener used in a majority of bonding situations, at lower temperatures and to produce a rapid cure that develops its physical properties quickly at room temperature. When mixed with the 105 Resin in a five-part resin to one-part hardener ratio, the cured resin-hardener mixture yields a rigid, high-strength, waterproof solid with excellent bonding and coating properties. Not intended for clear coating. (205 A size hardener is matched for use with 105 A size resin, etc.)
