BC-8002 is a two-part, fast-setting urethane tooling resin that cures (RTV) to a gray, Shore D85 plastic. This filled system offers low viscosity, low exotherm and minimal shrinkage and is ideal for constructing patterns, prototypes, duplications, negatives, low temperature vacuum form tools, tracing models, and other tooling applications.
Mix Ratio 1A:1B by weight or volume
Shore Hardness D85
Pot Life 5-6 min.
Demold Time 1-2 hr.
Cured Color Gray
Mixed Viscosity 2,350 cP
Specific Gravity 1.8-1.9
Specific Volume 15 in³/lb
Heat Deflection Temp. 179°F
Linear Shrinkage 0.0008 in/in
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.
