West System Fast Hardener

A medium-viscosity epoxy curing agent. Used in a majority of situations, at lower temperatures and to produce a rapid cure that develops its physical properties quickly at room temp[,;'erature. 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, moisture resistant solid with excellent bonding and coating properties. Not intended for clear coating. Pot life at 72F (22C): 9 to 12 minutes. Cure to a solid state: 6 to 8 hours. Cure to maximum strength: 1 to 4 days. Minimum recommended temperature: 40F (4C). Pumps required: (5:1 ratio) 301, 306 or 309.
