Polyvinyl alcohol (PVA) is often utilized as a mold release agent in industries such as plastics, rubber, and composites. Here's how it works:

  1. Coating: PVA can be applied as a thin film or coating onto the surface of a mold or other surface where sticking might occur.
  2. Barrier: Once applied, the PVA forms a barrier between the surface and the material being molded or worked with, preventing adhesion.
  3. Water Solubility: PVA is water-soluble, which means that after the molding process is complete, the PVA can be easily washed away with water, leaving behind the molded object.
  4. Smooth Finish: PVA can also contribute to a smoother surface finish on the molded object, as it helps in preventing imperfections caused by sticking.

It's important to note that while PVA can be effective as a release agent in certain applications, its performance depends on the specific materials, processes, and conditions involved. For other applications, different types of release agents might be more suitable. Always ensure to test the compatibility and effectiveness of any release agent in your specific use case before widespread application.

PVA should be used to aid in the release of parts from a mold. It should be applied in three thin mist coats over nonporous, waxed mold surfaces. After the final wax coat has dried, begin by spraying a light tack coat of PVA. Typically, within 5 minutes the final heavier coats can be added. The PVA dries to form a smooth, glassy film. After part release, the residual film can be removed with water. PVA can also be sprayed over any polyester repair to provide an airless tack-free cure. Size - 4L Part # 55426
