DKW-4013D Water-Based Semi-Permanent Mold Release

DiamondKote DKW-4013D is a water-based, silicone free, semi-permanent mold release agent designed for use in the molding of silicone elastomers. DiamondKote DKW-4013D promotes good rubber flow without significant transfer and offers excellent release characteristics. Typical applications include the molding of seals, o-rings, and gaskets. DiamondKote DKW-4013D can also be effective on a variety of peroxide-cured elastomers including EPDM, FKM, and HNBR, and is particularly effective on silicone and fluorosilicone elastomers. DiamondKote DKW-4013D is sold as a ready to use material and does not need to be diluted prior to use. 

Founded as Franklynn Industries, Inc. in 1991 offering DiamondKote, Aqualift, and later added Crystal brands.  Now part of the ITW Pro Brands team.
