MAC 444NPB NonFlammable Mold Release Agent and Dry Lubricant

Description:

MAC-444NPB is a nonflammable, solvent dispersion of a solid active ingredient, which exhibits low friction and excellent anti-stick/ release characteristics. The product furnishes a release coating effective with all types of rubber and plastic compounds and works equally well on metallic and nonmetallic molds at temperatures up to 550°F. The low coefficient of friction of the coating, makes it an excellent dry lubricant.

Technical Data:

  • Color and appearance.......White, translucent dispersion
  • Dispersing medium.............n-Propyl Bromide
  • Flash Point.........................None
  • Boiling point of solvent......159°F
  • Specific gravity...................1.32
  • Weight per gallon (lbs.).....10.6

Application Method:

  • Surfaces must be thoroughly cleaned and dried before applying MAC-444NPB. All traces of prior release agents should be removed by cleaning. McLube Mold Cleaner can be used.
  • MAC-444NPB is intended for use as supplied. Since the product is a dispersion of solid particles, agitation is required prior to use and periodically during use. Any conventional application method can be used - spraying, dipping, wiping or brushing. A thin, even coating should be applied, and after the solvent has evaporated, a second coat is recommended. The double coating is suggested for start-up on a clean surface. For the first few cycles, a single coat of MAC-444NPB is recommended for each cycle. Once the mold is conditioned, it may be possible that several cycles per application can be obtained, depending on the particular material being released.

Safety and Handling:

    The Material Safety Data Sheet for MAC-444NPB should be reviewed before using the product. Use only with adequate ventilation, especially in enclosed areas. The active ingredient is essentially nontoxic, but if heated over 550°F, it may form potentially harmful substances. Smoking should not be permitted while using MAC-444NPB, and contamination of tobacco products should be avoided. Safety glasses and gloves are recommended when using this product.
