GruberCare Mold Release Products Print

"Mold Release" is a term that relates to the preparation of a mold surface, to prepare that surface for multiple "pulls" (casting cycles). The goal is to ensure that a casting releases from the mold each and every time. The best solution to ensure this is to use our GruberCareSemi-Permanent Mold Release products.

Choose mold care products for wax- or polymer-based mold release systems, or our new advanced polymer-based MR CA series for a broad range of composites manufacturing applications.

  • GruberCare - designed for maintaining wax-based mold release products, and includes wax cleaners, sealers, strippers and wax-based mold release agents.

  • GruberCare MR Series - designed for polymer-based release systems, and includes polymer cleaners, sealers, strippers and wax-based mold release agents.

  • New Advanced GruberCare "MR CA" Series - advanced polymer-based formulation for a broad range of composites manufacturing applications.
