Polytek Poly 1511 Liquid Plastic

Mix Ratio: 1A:1B Shore Hardness: D71 Pour Time: 1 min. Demold Time: 1-16 hr. Cured Color: White Poly 1511 Liquid Plastic is a two-part, liquid polyurethane resin that cures (RTV) to a white, Shore D71 plastic. This product has a simple 1A:1B mix ratio by weight. When cured, it has the feel and density of hard wood or thermoplastics. Poly 1511 is a pourable plastic, but it can be easily thickened with PolyFiber II Thickener for brush-on application. Notes: Shake or Stir 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.
