McLube 1733L Mold Release Agent


McLube 1733L is a solvent dispersion of a solid active ingredient which produces a dry, colorless coating exhibiting excellent release/anti-stick characteristics. The coating is flexible and is particularly suited for use on nonmetallic molds, such as epoxy, polyester or silicone as well as on metal molds. It is especially effective for release of polyurethane compounds and polyester or epoxy fiberglass composites.

Technical Data:

  • Color and appearance..................White, translucent dispersion
  • Dispersing medium......................Solvent blend - heptane, ethanol, butyl acetate
  • Specific gravity............................0.78
  • Weight per gallon (lbs.)................6.5

Application Method:

    McLube 1733L is intended for use as received. It is a dispersion of solid particles and must be mixed prior to use and periodically during use. Any conventional method can be used for application - spraying, dipping, wiping or brushing. On a fresh mold, a thin, even coat should be applied, followed by a second coat, once the solvent has evaporated from the first. For the first few cycles, coating the mold each cycle is suggested, but once conditioned, several cycles should be obtainable. Molds should stay cleaner longer. For use as an anti-stick coating for process equipment the rate of application will vary with operating conditions and the materials being processed. More frequent reapplication is generally required at start-up. Product is particularly effective in reducing buildup of resins, inks and adhesives.

Safety and Handling:

    The Material Safety Data Sheet should be reviewed before using McLube 1733L. The precautions to be observed in handling McLube 1733L are those related to the solvent blend in the product - heptane, ethanol, butyl acetate. These solvents are flammable, and thus, the product should be kept away from heat, sparks and flames. Use only with adequate ventilation, especially in enclosed areas. The active ingredient is essentially nontoxic, but heating it above 550°F may cause formation of potentially harmful substances. Smoking should not be permitted while using McLube 1733L, and contamination of tobacco products should be avoided. Safety glasses and gloves are recommended when using this product.
