GruberCare Mold Release Wax Print

010630-lg

GruberCare Release Wax is a blend of high-melting point waxes formulated for the Cultured Marble industry and other applications, and is particularly well suited for demolding requirements of today’s modern fiberglass molds from Gruber and others. The wax is easy to apply and provides a high-gloss with low surface tension for superior release with maximum mold protection.

GruberCare Mold Release Wax contain a blend of synthetic waxes which reduce the quality fluctuations that are found in natural organic waxes, such as carnauba. Synthetic waxes used have high melt points and proper hardness to get the desired properties of film developed on the molds. The resulting film has high gloss and intensive wear resistance under the high or low temperature molding conditions. This assures the easy release.
