Ultra 3 Mold Release

The Ultra 3 family of mold releases is the next generation of our time-proven Ultra products. This premium family of mold releases retains all of the desirable characteristics of Ultra II, but incorporates a non-flammable solvent suggested by the Significant New Alternatives Products (S.N.A.P.) sector of the EPA.

Ultra 3 mold releases represent a balance of environmental responsibility, worker safety, manufacturing practices and economy to create the most economical and effective mold release you can buy.

  • Net weight: 18 ounces. 50% more mold release per can than most competitors results in more releases per can and less cans to recycle.

Ultra 4 Mold Release

The Ultra 4 group of mold releases is a new concept of solvent-less mold releases engineered specifically for plastics that exhibit heightened solvent sensitivity. Release agent deposition is fast, dry, and quick; therefore, it will not effect solvent-sensitive plastics as other mold releases with aggressive solvents may.

The release agents are the same time proven and reliable actives found in our other Ultra mold releases. Use Ultra 4 with complete confidence.
