Impact Resistant Urethane Resin - Black and Tan

3 complete drum kits of Black urethane casting resin is a semi-rigid plastic with some flexibility that is strong and tough. Originally developed for high impact tooling, this product also offers abrasion and chemical resistance. It is ideal for a variety of industrial applications and fabrication of military training aids. Each of the three kits consists of two 55-gallon drums (Part A and Part B). The mixed resin is low in viscosity and does not require vacuum degassing. Technical Overview: Mix Ratio: 100A : 60B by weight; Mixed Viscosity cps.: 3,500 (ASTM D-2393); Specific Gravity, g/cc: 1.08 (ASTM D-1475); Specific Volume, cu. in./lb.: 26 (ASTM D-1475); Pot Life: 20 minutes @ 73?F / 23?C (ASTM D-2471); Handling Time: 4 hours @73?F / 23?C, depending on mass: Full Cure: 48 hours @ 73?F/23?C or 6 hours @150?F/60?C, depending on mass; Color: Black; Shore D Hardness: 63 (ASTM D-2240); Die C Tear Strength, pli: 488 (ASTM D-624); Ultimate Tensile, psi: 4,280 (ASTM D-638); Elongation @ Break: 400% (ASTM D-638); Shrinkage, in./in.: 0.001 (ASTM D-2566); Heat Distortion Temperature: 150?F / 60?C; Izod Impact Resistance (ft*lb/in): 16.1. Shipping with Lead Time of 30 days or less. Must be compatible with any brand of mold release. Material that does not cure properly must be replaced by the vendor at no cost to the government. 1 complete kit of Tan urethane casting resin, semi-rigid plastic with some flexibility that is strong and tough.
