Reynolds PMC® 780 Dry & Wet Industrial Liquid Rubber Compound
Categories: Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Liquid

Material Notes: Product Overview: PMC-780 is a premium performance urethane rubber that offers exceptional strength, durability and abrasion resistance. PMC-780 DOES NOT CONTAIN MOCA – a known cancer causing agent and hazard. Mixed two parts A to one part B by weight or volume, PMC-780 urethane pours easily and cures at room temperature with negligible shrinkage to a solid Shore 80A rubber. Pick The One Best Suited For Your Application: Original PMC-780 Dry does not exude oil. New PMC-780 Wet contains a built in release agent to aid in demolding concrete. (Note: “wet” rubber has a higher net shrinkage value over time vs. “dry “ rubber.) Both are used around the world for casting abrasive materials such as concrete (pre-cast concrete, making concrete stamping pads, etc.) and gypsum plasters with high exotherms. PMC-780 Dry is also commonly used to make rubber mechanical parts of varying configurations (gaskets, wheels, and pullies) as well as ball mill liners and vibration/shock pads.
