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 demoulding 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.
