West 205

205 Fast Hardener is a medium-viscosity epoxy curing agent.It is 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 WEST SYSTEM 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.
