DiamondKote DKW-4013A 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-4013A is effective on a variety of peroxide-cured elastomers including EPDM, FKM, and HNBR, and is particularly effective on silicone and fluorosilicone elastomers. Sold as a ready to use material and does not need to be diluted prior to use.
