Product Details

Mix Ratio: 1A:1B
Shore Hardness: D8
Pour Time: 15 min.
Demold Time: 12-16 hr.
Cured Color: Tan

Poly 15-3 Liquid Plastic is a two-part, liquid polyurethane resin that cures (RTV) to a tan, Shore D8 plastic that has the feel of dense stone. This is a mineral-filled system with a simple 1A:1B mix ratio by weight. The filler makes Poly 15-3 a very economical, low-cost resin and also reduces exotherm so shrinkage is minimal; Poly 15-3 and Poly 15-3X (the faster-setting version of Poly 15-3) exhibit the least shrinkage on cure compared to other Polytek polyurethane plastics. Poly 15-3 is a pourable plastic, but it can be easily thickened with PolyFiber II Thickener for brush-on application.

Notes: Shake or Stir Part A & Part B before use. Demold time varies with thickness of casting. The thinner the casting, the longer the demold time. Shrinkage in polyurethane resins is caused by gelling while hot then cooling. Parts that cure with minimal temperature rise (exotherm) exhibit minimal shrinkage. The color of polyurethane Part Bs may change in color from batch to batch or may darken with age, but product performance is not affected.
