MAC 968 NanoParticle Water Based Semi-Permanent Release Coating


MAC-968 is a colloidal dispersion of finely divided PTFE (polytetrafluoroethylene) particles in water. It forms a clear, dry, colorless film coating that is extremely durable. It has proven to provide excellent release and antistick properties for a variety of rubber compounds and plastic parts.

Technical Data:

  • Color and appearance............Translucent, off-white colloidal dispersion
  • Dispersing medium................Water
  • Specific gravity…....................1.01
  • Weight per gallon (lbs.)..........8.4

Application Method:

    MAC-968 is intended to be applied as received to clean, dry surfaces. All previously used release products and any compound residue should be removed by an appropriate method. McLube Mold Cleaner May be used. Application can be accomplished by spraying a thin, even film over the entire surface to be treated and allowing to dry. To assure complete coverage, apply a second coating. Maximum durability of the coating is obtained once the coating is dry. Proceed to mold as usual. MAC-968 will provide superior release performance for a number of parts. Reapplication can be accomplished by applying only one coating as needed.

Safety and Handling:

    The Material Safety Data Sheet, which accompanies each shipment, should be reviewed prior to using the product. Freezing of the product should be avoided, but if it occurs, it is possible to restore product uniformity with mechanical agitation. The active ingredients in MAC-968 are not toxic, but heating the solids above 500ºF may result in possible formation of harmful fumes. Smoking should not be permitted while using the product and contamination of tobacco products should be avoided. Safety glasses and gloves are recommended when using this product.
