West System 205 Fast Hardener is a low-viscosity epoxy curing agent for use when shorter working and cure time is needed or to provide adequate working time at cooler temperatures.

At 72-degrees, 205 Fast Hardener will have a 9-12 minute Pot Life. When combined with WEST 105 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.

Not intended for clear coating.
