TotalBoat 5:1 Slow Hardener is 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. Use with both TotalBoat 5:1 Epoxy Resin and all traditional 5:1 epoxy brands.
At 75°F, our Slow Hardener will have a pot life of 20 minutes. When combined with TotalBoat 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.
