MAC 799 Water Based Mandrel Lubricant for Filament Winding


MAC-799 is an aqueous dispersion of finely divided particles of PTFE (polytetrafluoroethylene). It will air cure in minutes providing a durable, dry, colorless film with excellent lubricating properties, a low coefficient of friction, and excellent stick-slip characteristics.

Technical Data:

  • Color and appearance......Translucent dispersion
  • Dispersing medium...........Water
  • Coefficient of friction..........0.1
  • Specific gravity..................1.02
  • Weight per gallon (lbs.).....8.4

Application Method:

    MAC-799 is intended to be used as received but can be diluted with water if application dictates a low viscosity. Since the product settles on standing, agitation is required to maintain a uniform dispersion. Product should be applied to a clean, dry surface by spraying, wiping, dipping or brushing. External heat can be used to speed up drying time. Apply a thin even film on the mandrel surface and allow to dry.

Safety and Handling:

  • The Material Safety Data Sheet for MAC-799 should be reviewed prior to using the product.
  • The active ingredients in MAC-799 are essentially nontoxic, but heating the solids above 550°F may result in possible formation of potentially harmful substances. 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.
  • Freezing of the product should be avoided, but if freezing occurs, it is possible to restore product uniformity with mechanical agitation.
