Polymer-based Mold Release:
GruberCare MR Series Polymer-based Mold Release Products
Designed for polymer-based release systems, and includes polymer cleaners, sealers, strippers and wax-based mold release agents.
GruberCare MR GP Polymer Release Agent
(General Purpose) Multi-Release
- Step 5A of the GruberCare Semi-Permanent Mold Release System
- Recommended for fiberglass molds for cultured marble and solid surface applications.
Grubercare MR GP (Step 5A) is a multi-release polymer topcoat applied over the MR Sealer. MR GP is formulated for multiple high gloss moldings of thermosetting resins.
- Easy application
- Non contaminating
- Non-chlorinated, Ecologically friendly solvents
- Low odor
- Minimal mold build-up
- Superior gloss retention
- Durable; provides multiple releases per application
GruberCare™ MR GP is a multi-release system yielding high gloss moldings. It 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 GP is an advanced polymeric resin in a non-chlorinated organic solvent blend. It is ideally suited for high gloss applications. The product is quick and easy to apply and produces a high gloss durable finish capable of giving many releases before reapplication is necessary.

Wax-based Mold Release:
GruberCare Wax-based 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.
