GruberCare™ MR Sealer

Step 4 of the GruberCare Semi-Permanent Mold Release System

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

GruberCare™ MR Sealer is designed as a mold sealer for glass reinforced polyester, vinyl ester, epoxy or metal molds. GruberCare™ MR Sealer is an advanced polymeric resin in an organic solvent blend. GruberCare™ MR Sealer is especially recommended for use on new molds and repaired areas on older molds.

For use in combination with the MR GP and MR HI-TEC products. It should be used to prevent styrene emission or migration from new molds and eliminate surface porosity of metallic molds. The resin both seals micro porosity and fills minor scratches on the mold surface. The result is a smooth, high gloss surface primed for GruberCare topcoat application. GruberCare™ MR Sealer is especially recommended for use on new molds and repaired areas on older molds.

Product Benefits:

  • Efficient mold sealer and primer
  • Easy application
  • Enhances mold gloss (see application details for appropriate coating technique)
  • Low odor
  • Minimal mold build-up
  • Versatile, can be used on all mold surfaces
  • Durable; provides semi-permanent base-coat for mold release agent top coats
