Internal Mold Release Agents for Specific Composites Molding Applications
Chem-Trend has developed special internal release agents for the composite molding industry that are utilized for two major purposes:
- Enhance the function of external release agents. In examples like Resin Transfer Molding, the addition of the specialty Chemlease® internal release agents to the resin assists the other components of the release system in keeping the mold surface clean and free from scumming (build-up) for an extended period of time.
- Provide internal lubrication to the resin. I-beams produced by composite pultrusion for the construction industry benefit from the use of internal mold release agents. The correct Chemlease® internal release agent product, when mixed directly into the resin, provides lubrication at the die orifice which results in both faster extrusion rates and reduces die wear†.
