West System Slow Hardener

A low-viscosity epoxy curing agent for use when extended working and cure time is needed or to provide adequate working time at higher temperatures. When combined with 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 72°F (22°C): 20 to 25 minutes Cure to a solid state: 10 to 15 hours Cure to maximum strength: 1 to 4 days Minimum recommended temperature: 60°F (16°C)
