Poly 15-3X Liquid Plastic is a two-part, liquid polyurethane resin that cures (RTV) to a tan, Shore D80 plastic that has the feel of dense stone. This is a fast-setting, mineral-filled system with a simple 1A:1B mix ratio by weight. The filler makes Poly 15-3X a very economical, low-cost resin and also reduces exotherm so shrinkage is minimal; Poly 15-3X and Poly 15-3 (the slower setting version of Poly 15-3X) exhibit the least shrinkage on cure compared to other Polytek® polyurethane plastics. Poly 15-3X is a pourable plastic, but it can be easily thickened with PolyFiber II Thickener for brush-on application.
