McLube offers a diverse line of mold release agents for synthetic composites, engineered wood, and engineered stone. McLube’s consummate line of mold release agents for synthetic composites includes many different product options all designed to enhance flow during curing steps, reduce transfer to the molded part, and promote excellent surface finish. Reduced transfer will improve part appearance and cut down on prep time for painting and gluing (if applicable). All McLube composite release agents contain proprietary rust-inhibiting additives to extend the lifespan of molds and tooling. Our products for composite release are thermally stable to 1,000°F and furnish chemically inert coatings that will not interfere with material integration. McLube’s line of synthetic mold release agents includes water and solvent-based conventional and sacrificial mold release coatings. We also offer tin-free and VOC-free options for molding a variety of composite materials.

Reduce Scrap Rates and Improve Surface Finish

Our composite release agents are designed to provide reliable release characteristics without building up on the mold surface. Reduced buildup will cut down on cleaning time and frequency as well as reduce rejection rates due to poor surface finish or failed release. McLube offers composite release agents for the following surface finishes:

 

  • Glossy
  • Matte
  • Satin

McLube Formulation Chemists may also engineer a new formula for unique surface finishes.
