Pro Marine Supplies Epoxy Hardener Fast is a low-viscosity epoxy curing agent for use when shorter working and curing times are needed. Our 521 Fast Hardener provides adequate working time at cooler temperatures. 

At 75°F, Pro Marine Supplies Epoxy Hardener Fast will have a pot life of 12 minutes. When combined with our 521 Epoxy 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.
