  • Dispersing medium - Water
  • Specific gravity - 1.01
  • Weight per gallon (lbs.) - 8.4

Application Method:

    Apply the product as received to a clean, dry mold. It may be necessary to use a solvent-based cleaner to remove prior release coatings, waxes or oils before application. Spray a thin, even film over the entire surface and allow to dry. To assure complete coverage, apply a second coating. Rate of reapplication will vary by process and material; one coat will be sufficient for reapplication.
