MAC 718 Engineered Wood Mold Release Agent


MAC-718 is a water dilutable emulsion of a resin mixture intended for use as a release coating in rubber molding processes and as an antitank coating for uncured rubber. This product represents an economically attractive replacement for the conventional release and antiseptic/antitack agents used in the rubber industry and, at the same time, offers superior properties to such agents.

Technical Data:

  • Color and appearance.................Milk white emulsion
  • Consistency...............................Water thin
  • Suitable diluent..........................Water
  • Emulsion type............................Nonionic
  • Weight per gallon (lbs.)...............8.3

Application Method:

    Optimum performance in using MAC-718 as an antistick/antitack agent for uncured rubber is achieved if MAC-718 (diluted) is applied to the rubber while it is hot. If the surface is not hot enough to dry the coating quickly, forced drying, using hot air or a heat lamp, is suggested. Applying MAC-718 dilutions to uncured rubber can be accomplished by spraying, flow coating or dipping. The optimum dilution rate for MAC-718 on uncured rubber will depend on the particular compound or process involved. Thus, some preliminary evaluations will be required to determine the lowest concentration that will furnish the desired antistick properties.

Safety and Handling:

    The Material Safety Data Sheet, which accompanies each shipment, should be reviewed prior to using MAC-718. Freezing of the product should be avoided. MAC-718 has avery low order of toxicity. If product contacts the eyes, minor irritation may result, but flushing with water will minimize any discomfort. Prolonged contact with the skin should be avoided.
