We offer a variety of Mold Release (Polymer Release Agents) for use with cultured marble molds, solid surface molds, and a broad variety of other composites.
Some of the products below are part of the GruberCare Semi-Permanent Mold Release System. Learn more about these products, and how to use them as a complete mold care system for fiberglass molds used in cast polymer manufacturing applications.
GruberCare™ MR Series Mold Release Products
Designed for polymer-based release systems, and includes polymer cleaners, sealers, strippers and wax-based mold release agents.
GruberCare MR GP
(General Purpose) Multi-Release
Recommended for fiberglass molds for cultured marble and solid surface applications.
Multi-release system yielding high gloss moldings. GruberCare MR GP is designed to release gel-coated glass reinforced polyester or vinyl ester parts from gel-coated molds. Purposely formulated for reinforced polyester resins or high gloss moldings using gelcoats and increased temperature performance.
GruberCare MR Hi-Tec
GruberCare MR Hi Tec is designed for special applications where rapid curing, high gloss and slip properties are required. Excellent for metallic molds or molds of high surface porosity such as modular molds or molds of integral shape. Purposefully formulated for use a a mold release agent for rotational molding and phenolic resin molding. It is also designed to release epoxy, polyester, vinyl ester, phenolic and other thermosetting resins. Provides a durable film capable of giving many releases per application and will not contaminate the released surface.

GruberCare MR 2-IN-1
GruberCare 2-IN-1 Combination Time Saver is a high solids, high slip semi-permanent polymer release product. Its function is to save time both in establishing the release foundation and effectively maintaining that foundation during the production life of the tool. Since the inception of semi permanent release technology, it has been customary to first apply several coats of Sealer, each requiring 15 minutes to cure, before applying several coats of Top Coat Release and again waiting for each to cure for 15 minutes. This has been true for both MR 2 in 1 and other semi permanent systems as well. Some industries may find this standard to perform best, however, most will find they can apply the same foundation for their needs in only three coats of MR 2 in 1. This should reduce the time spent in preparing a new tool by half. Most tools should take no more than 60 minutes to make ready for production.
GruberCare™ Mold Release Agents
Designed for maintaining wax-based mold release products, and includes wax cleaners, sealers, strippers and wax-based mold release agents.
Mold Release Wax
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.
GruberCare Interphase Wax is a liquid blend of high-melting point waxes formulated as an interphase release to minimize dulling wax build-up caused by continuous use of Release Wax. When used in conjunction with GruberCare Release/Indicated Wax, time between mold strippings can be extended significantly. Use Interphase Wax approximately every 10 castings or when dulling wax build-up begins to appear on the mold surface.

GruberCare Flange Wax is a blend of tough, low luster waxes formulated for use on flanges, mold boxes, backsplash doors, hinges, and female hats or any spot where easy release of marble matrix is more important than the finish obtained. When properly applied, flange wax will simplify mold clean-up, minimize repairs and extens mold life.
