GruberCare MR Series Mold Release Products

Designed for polymer-based release systems, and includes polymer cleaners, sealers, strippers and wax-based mold release agents.

MR-GCA350

GruberCare MR GCA

Specifically formulated for Glass Reinforced Polymers (GRP) applications such as open molded glass reinforced polyesters and vinyl esters - as well as certain closed molding applications.

GruberCare MR GCA enables a high gloss finish to be obtained easily and with minimal effort. GruberCare MR GCA also offers excellent durability and  multiple release performance.  It also releases gelcoated glass reinforced polyester (GRP) or vinyl ester parts from gelcoated molds.


MR-ACA-350

GruberCare MR ACA

Release composite materials - such as all types of epoxy, phenolic, polyester (GRP) or vinyl ester resins from steel, aluminum or composite molds.

A general purpose semi-permanent mold release agent. GruberCare MR ACA is designed to release most thermosetting polymers (except isocyanate based polymers and silicones). GruberCare MR ACA is typically used to release composite materials - such as all types of epoxy, phenolic, polyester (GRP) or vinyl ester resins from steel, aluminum or composite molds.


GruberCare MR GP polymer mold release agent

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.


MR0304-SM

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 Interphase Wax Mold Release Agent

Interphase Wax

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 Mold Release Agent

Flange Wax

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.

PVA Concentrate

  • Protect mold surfaces during casting
  • Protect molds
  • Mold release
  • Used for mold break-in

A non-flammable product formulated to Gruber specifications for the cultured marble industry's use to protect molds during the mold break-in process. PVA may also be required when molding to irregular surfaces or other conditions requiring additional protection during casting.
