Polymer Release Agent Remover


Product Description:
A clean mold is essential to enable a semi-permanent mold release agent to give maximum performance. GruberCare MR Stripper CA is a blend of organic solvents designed to make mold cleaning as easy and effective as possible. It is designed to remove dirt, grease, and contaminants from a mold surface, and is particularly efficient at removing silicone, wax or other types of buildup on a mold surface. For its all-around cleaning ability, GruberCare MR Stripper CA has been described as the best on the market. GruberCare MR Stripper CA is designed not to soften or dull mold materials (such as GRP). Consequently, GruberCare MR Stripper CA can be used on any metallic or thermoset mold. GruberCare MR Stripper CA should be used immediately prior to the application of GruberCare MR Sealer CA (or other Sealers or Release Agents).

Please read Material Safety Data Sheet (MSDS) before use. Heavy build-up and resin deposits may be removed by an abrasive medium, e.g. polishing compound or even shot blasting, prior to using the GruberCare MR Stripper CA. If necessary, polish mold to desired level of gloss prior to using the GruberCare MR Stripper CA.

  1. Generously apply GruberCare MR Stripper CA to a clean, dry cotton cloth.

  2. Wipe over mold surface covering an area of approximately 0.5m2.

  3. With a second dry cloth, wipe off the wet film. Do not allow the wet film to dry before wiping off as this will simply redeposit contaminants picked-up by the solvent. Continue wiping until the mold surface is dry.

  4. Repeat Steps 1 -3 on the adjacent area. Ensure a good overlap with the previous area to ensure the entire mold surface is cleaned.

  5. If either cloth becomes dirty, or if the second cloth becomes wet, replace with a fresh clean cloth and repeat Steps 1-4.

  6. Frequently re-apply GruberCare MR Stripper CA to the wet cloth.

  7. Repeat until mold is completely cleaned.

Test for Cleanliness:

Visually inspect the mold for signs of dirt or streaks. If necessary, repeat cleaning procedure in that area. To test the cleanliness of the surface, apply a standard pressure sensitive tape (e.g. masking tape) to the mold surface. When the tape is removed from the surface, stiff resistance should be observed. If the tape fails to stick firmly, repeat cleaning procedure.

Note: If polishing a GRP mold, it is recommended that a non-wax containing polish be used. If a polish containing a wax is used, the wax produces an artificial gloss that will be removed by GruberCare MR Stripper CA, hence dulling the finish.
