AXEL MoldWiz internal mold releases (IMRs) will: > offer easy mold release > improve cosmetics > reduce surface porosity > promote better wetting of reinforcements > improve dispersion of color and fillers > eliminate stress marks > produce clean parts, ready for finishing IMRs for Composites AXEL's internal releases for thermosets are proprietary polymer products designed to be partially compatible with the resin. This permits some of the lubricant to cross-link with the resin during the cure, while the balance is emitted as a vapor, creating the release interface between part and mold. Interlaminate strength, especially the bond between the laminate and gel coat, is not weakened, because the exothermic heat drives the vapor to the mold surface. Internal releases require heat to function. Heat can be generated by the exotherm of the resin, by heated mold surfaces, or by oven or autoclave cure. Generally, applications which have minimum temperatures of 65°C/150°F and use metal tools are good candidates for internal mold releases. With FRP molds, adding an IMR to the gel coat will reduce porosity and improve release and appearance of parts, although periodic use of an external release is still recommended to seal the porosity of the mold surface. For composite applications, liquid internal release is added to the less viscous or reactive thermoset component before mixing. The recommended starting point for evaluating an IMR is 0.5% of the resin by weight. In highly filled resin systems, the recommended range can be higher. We suggest that customers run gel tests with and without IMR to evaluate any changes prior to using the lubricant in production. Should a radical change occur, a different internal release should be considered.
