MAC 860 - Semi-perm Release Agent


Durable semi-permanent coating effective up to 1000°F. Available in aerosol cans.

Technical Data:

  • Color and appearance - Milky, white liquid
  • Dispersing medium - Water
  • Specific gravity - 1.0
  • Weight per gallon (lbs.) - 8.3

Application Method:

    MAC-860 may be applied as received or diluted with deionized water (1:1 to 1:4 water). Your ability to dilute the product will depend on your specific process and materials- we recommend the product be used as received. Apply to hot or cold molds; preheating the mold to at least 200°F will facilitate evaporation. Proper application of the release coating will help achieve the maximum number of releases per application. We recommend you use McLube Mold Cleaner to prep and clean your mold. Apply a light, even spray to the mold. Apply a second coat when the first has completely dried. The mold should be heated to 300°F or higher and held for at least five-minutes to cure after application. MAC-860 can be sprayed on a hot mold for touch-up.

Safety and Handling:

    Review the Safety Data Sheet before use. None of the ingredients in MAC-860 are considered hazardous, however, good industrial practice suggests the use of proper safety equipment. Product should be kept from freezing. Container should be kept covered to prevent evaporation and contamination.
