MAC 860 Water Based Semi-Permanent Mold Release Agent
Description:
MAC-860 is a water based emulsion of a film forming resin that cures to form a clear, colorless coating with excellent release and antistick characteristics. It is intended for use as a release coating for molding rubber compounds including EPDM, NBR, SBR, polyurethanes, fluoroelastomers and fiber/resin composites, including epoxy, polyester, thermoplastic and thermoset resins and fiberglass laminates.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 should be applied as received or diluted with deionized water, to a clean, dry mold. Typical dilutions range from one to four parts deionized water to one part MAC-860. It can be
applied to hot or cold molds, but preheating the mold to at least 200°F will facilitate evaporation of the water. Proper application of the release coating will help achieve the maximum number of releases per application. After cleaning the mold with a suitable solvent or an abrasive cleaner to remove previous release
agents or other contamination, a finely atomized, light, even spray should be applied to the mold. After allowing the water to evaporate, a second coat should be applied. The mold should then
be heated to 300°F or higher and held for at least five minutes to effect curing of the release film. For touch-up, MAC 860 should be sprayed as a fine mist to the hot mold.
Safety and Handling:
-
The Material Safety Data Sheet should be reviewed before using MAC 860.
None of the ingredients in MAC-860 is considered hazardous; however, good industrial practice suggests the use of safety glasses and gloves. Product should be protected from freezing. Container should be kept covered to prevent evaporation.
