PMC780 WET Drum Kit 660Lb (700651)
PMC-780 is a premium performance urethane rubber that offers exceptional strength, durability and abrasion resistance. Mixed two parts A to one part B by weight, PMC-780 pours easily and cures at room temperature with negligible shrinkage to a solid Shore 80A rubber. Pick The One Best Suited For Your Application: PMC-780 Dry does not exude oil.
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.
