McLube 1829 General Purpose Water Based Mold Release Agents. Bulk & Aerosol Spray


McLube 1829 general purpose mold release agent is a water dilutable emulsion of a fluorochemical/resin mixture intended for use as a release coating in rubber molding processes and as an anti-tack coating for uncured rubber. This product represents an economically attractive replacement for the conventional release and anti-stick/anti-tack agents used in the rubber industry and at the same time offers superior properties to such agents.

Technical Data:

  • Color and appearance..................Opaque white to off-white emulsion
  • Dispersing medium......................Water
  • Specific gravity............................1.01
  • Weight per gallon (lbs.)................8.4

Application Method:

    McLube 1829 is a concentrate and is intended to be diluted with water prior to application. A dilution rate of one part McLube to four parts water is suggested as a starting point, particularly while a mold is being conditioned. It may then be possible to use higher dilutions and still achieve excellent release results. Although McLube 1829 is a stable emulsion, as are the various dilutions, some separation may occur on standing. It is, therefore, recommended that the product and its dilutions be agitated prior to use and periodically during use. For optimum results, the surface to which McLube 1829 is applied should be clean and free of any oily residue or other release coating. The diluted product can be applied by conventional means such as wiping, or preferably, spraying. Ideally, the surface being treated should be hot to allow the water to evaporate quickly. APPLICATION TO UNCURED RUBBER: Optimum performance in using McLube 1829 as an anti-stick/anti-tack agent for uncured rubber is achieved if McLube 1829 (diluted) is applied to the rubber while it is hot. If the surface is not hot enough to dry the coating quickly, forced drying using hot air or a heat lamp is suggested. Applying McLube 1829 dilutions to uncured rubber can be accomplished by spraying, flow coating or dipping. The optimum dilution rate for McLube 1829 on uncured rubber will depend on the particular compound or process involved. Thus, some preliminary evaluations will be required to determine the lowest concentration that will furnish the desired anti-stick properties.

Safety and Handling:

    The Material Safety Data Sheet should be reviewed prior to using McLube l829. McLube 1829 has a very low order of toxicity; however, good industrial practices should be observed. Safety glasses and gloves are recommended when using this product. Prolonged contact with the skin should be avoided. Freezing of the product should be avoided.
