Internal mold release.
MoldWiz INT-220IMC internal mold release is designed for in-mold coatings used in reaction injection molding (RIM) processes. The proprietary formula is said to be easily miscible in water-borne polyurethane (PU) coatings that are typically employed in RIM processes to achieve either finished or primer painted surfaces on molded PU parts. The addition of 1% of INT-2201MC by weight to PU in-mold coatings is sufficient to cleanly release these coatings from steel tooling and to significantly enhance release from composite tooling, according to the company. Parts are said to be de-molded in as little as three minutes. (Axel Plastics Research Laboratories)
