Plasti-Paste™ EPOXY

Plasti-Paste EPOXY is an epoxy-based version of Smooth-On’s popular urethane Plasti-Paste products. It is a two component, fiber-filled epoxy designed for vertical surface application. Part A is a paste and Part B is a liquid. Mix ratio is 2A: 1B by volume or weight. Pot life is 40 minutes and cure time is 16 hours at room temperature depending on mass. Applying heat can reduce cure time. Mixed material holds a vertical surface without sagging and cures very rigid and strong.
