The hardener half of our Thick 1:1 epoxy system. Mix equal parts by volume with Thick Epoxy Resin, stir until the color is uniform, and you get 30 to 35 minutes of pot life at 80°F. Sets in 3 to 4 hours, dries hard in 12 to 14.

Buy it ala carte to rebalance your bench stock, or grab the complete kit if you are starting fresh. This hardener is matched to the Thick resin; for our Thin laminating resin, use the 2:1 or 4:1 hardeners instead.
