BROCK Material PMC 1706 Urethane Rubber Kit, 2 Gallon, Shore A60, 1:1 Mix, Amber

For professionals who demand a reliable room-temperature-curing urethane rubber, the BROCK Material PMC 1706 stands out with its balanced 1:1 mix ratio and forgiving 30-minute pot life. This 2-gallon kit delivers a flexible, high-strength material that captures fine detail without the brittleness common in budget alternatives.

Highlights

• Shore A60 hardness: flexible yet tough enough for demanding applications
• Simple 1A:1B mix ratio by weight or volume reduces measuring errors
• 30-minute pot life allows ample working time for complex molds
• Low mixed viscosity (1000 cps) ensures excellent flow into intricate details
• Negligible shrinkage (<0.001 in/in) preserves dimensional accuracy

In daily use

PMC 1706 excels in casting, mold making, and producing industrial parts such as gaskets, seals, and impact pads. Its cured amber color provides a neutral base for pigmentation if desired. The material offers good resistance to many solvents, oils, and fuels, making it suitable for automotive and industrial environments. Demold parts after 16 hours; full properties develop over 7 days. With a maximum operating temperature of 85°C, it handles moderate heat without softening.
