PMC®-780 WET

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.

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.
