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.
PMC™-780 DRY is 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.
