Pour Clear Polyester Casting Resin into any mold to make a paperweight, or sculpture. Casting resin is a crystal clear, low viscosity liquid that requires mixing with a catalyst to become rock hard (purchase catalyst separately). It cures to a smooth glossy transparency at room temperature. Use of a mold release is not necessary for flexible plastic or rubber molds.
Note — Casting resin has only a 6-month shelf life. Store in a cool place.
Polyester Catalyst — Clear, colorless liquid, very low viscosity. Usually added in quantities of 0.5% to 3.0% of weight of resin for curing. Store in a cool place, keep tightly closed. Purchase ½ oz for a pint or quart of resin, and 1 oz for a gallon of resin.
