TotalBoat Fast Hardener is a low-viscosity epoxy curing agent for use when shorter working and curing times are needed. Our 5:1 Fast Hardener provides adequate working time at cooler temperatures. Use with both TotalBoat 5:1 Epoxy Resin and all traditional 5:1 epoxy brands.
At 75°F, TotalBoat Fast Hardener will have a pot life of 12 minutes. When combined with 5:1 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.
Note: Not intended for clear coating applications. For clear coating applications, use TotalBoat Traditional Epoxy Resin with TotalBoat Crystal Clear Hardener.
