HS-930 Mold Release for Gel-Coat

HS-930 is a high-performance, single component, wipe-on, ambient air cured product.  It creates a covalent bond to the substrate giving it an intrinsic bond to the mold tool.  HS-930 is an inert (benign) material containing no “free silicones”.  It has excellent release properties with Gel-coat and other surface coatings.

This VOC-exempt solvent-based release is especially formulated for Gel-coat layups with the use of multiple coats of waxes, allowing for easy part pulls and reduced chance of mold tool damage and labor savings.

  • Spray or wipe-on application, ambient cure, and short dry time
  • Single application is all that is needed on an ongoing production basis
