McLube 1725L - Mold Release, Protective Coating, Dry Lubricant


McLube 1725L is a solvent-based PTFE dispersion with a low coefficient of friction and excellent anti-stick/ release properties. The product will work well on metallic and nonmetallic molds at temperatures up to 550°F. McLube 1725L will protect molds in storage from corrosion. This product is particularly useful for reducing the buildup of resins, inks, and adhesives.

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:

    Apply the release agent to a dry mold free of previous release coatings, waxes and oils. We recommend using a solvent cleaner to prep the mold for application. Do not dilute the product. Mix the release coating well before use and periodically through application. Any conventional method can be used for application - spraying, dipping, wiping or brushing. On a fresh mold, a thin, even coating should be applied, followed by a second coat once the solvent has evaporated. For the first few cycles, coat before every cycle. Once the mold has been conditioned, you will get multiple releases per cycle; your specific process and materials will determine when you must reapply. McLube 1725L is also an excellent protective coating. Clean the mold and apply two coatings before storage. When the mold is taken from storage, it can be returned to the press without cleaning, although wiping with a non-linen cloth is suggested.

    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.

Safety and Handling:

    Review the Safety Data Sheet before use. McLube 1725L is flammable and should be kept away from heat, sparks, and flames. Use only with adequate ventilation in enclosed areas. The active ingredient is essentially non-toxic but temperatures above 550°F may cause formation of harmful substances. Smoking should not be permitted while using McLube 1725L and contamination of tobacco products should be avoided. Always wear the appropriate safety equipment when handling 1725L.
