MAC 973 Water Based Mold Release Agent for Composites

Description:

MAC-973 is a water based, milky-white, translucent emulsion of a film forming resin that will cure to form a clear, colorless coating designed for epoxy, polyester, thermoplastic, thermoset resins and fiberglass laminates. It will provide outstanding release, anti-stick and lubricity properties.

Technical Data:

  • Color and appearance................Translucent, milky-white liquid
  • Dispersing medium.....................Water
  • Specific gravity............................1.0
  • Weight per gallon (lbs.).............. 8.32

Application Method:

  • Proper application of the release coating is critical to achieve the maximum release-per-application performance attributes. The mold should be cleaned with a suitable solvent or abrasive cleaner to remove previous release coatings and any part material contamination. McLube Mold Cleaner may be used. Application can be accomplished by wiping with a soft cotton cloth or spraying a fine mist to produce a thin, even film coating over the entire mold surface. Allow to dry and apply a second coating on new tools. Coat the entire surface to be treated but do not over apply. Proceed to mold your part as usual. MAC-973 can be reapplied as needed.

Safety and Handling:

  • The Material Safety Data Sheet for MAC-973 should be reviewed before using the product.
  • None of the ingredients in MAC-973 are considered hazardous; however, good industrial practices suggest the use of safety glasses and gloves.
  • Product should be protected from freezing.
  • Container should be kept covered to prevent evaporation and eliminate any product contamination.
