McLube 1711L Mold Release Agent for Hard to Mold Parts. Aerosol Spray and Bulk Packaging


McLube 1711L is a solvent dispersion of a solid active ingredient exhibiting low friction and excellent anti-stick/ release characteristics. This product, recommended particularly for application to heated surfaces, furnishes a dry, colorless coating which is effective for releasing rubber and plastic compounds and providing multiple release cycles without transfer to molded parts and with no buildup on the mold. The coating is identical to that obtained with McLube 1700L which is recommended for application to surfaces below 150°F. McLube 1711L is particularly effective for release of difficult to mold organic rubber parts and silicone rubber compounds.

Technical Data:

  • Color and appearance................White, translucent dispersion
  • Dispersing medium....................Solvent blend - heptane, ethanol, butyl acetate, propyl cellosolve
  • Specific gravity..........................0.84
  • Weight per gallon (lbs.)..............7.0

Application Method:

    To ensure optimum release results, mold surfaces must be cleaned thoroughly and dried prior to molding. All traces of previously used release agents should be removed. McLube Mold Cleaner can be used. McLube 1711L is intended for use as received. Since McLube 1711L is a dispersion of solid particles which settle on standing, the product must be mixed prior to use and periodically during use. Conventional application methods can be used - spraying, dipping, wiping, brushing. On a fresh mold, application of two coats is suggested, allowing for solvent to evaporate prior to applying the second coat. For the first few cycles, coating the mold each cycle is suggested. Subsequent to this break-in period, several cycles should be obtainable for each application of release coating.

Safety and Handling:

    The Material Safety Data Sheet on McLube 1711L should be reviewed before using the product. The precautions to be observed in handling McLube 1711L are those related to the solvent blend in the product. 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 above 550°F, may cause formation of potentially harmful substances. Smoking should not be permitted while using McLube 1711L, and contamination of tobacco products should be avoided. Safety glasses and gloves are recommended when using this product.
