Pro Marine Supplies 521 Epoxy Hardener Slow 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.

At 75°F, our Slow Hardener will have a pot life of 20 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.
