McLube 1829 - Concentrated Release Agent


McLube 1829 is a cost effective mold release agent for all rubber compounds and an effective anti-stick solution for uncured rubber. This product is a cleaner, less cumbersome alternative to silicone oils and soap. McLube 1829 is sold as a concentrate.

Technical Data:

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

Application Method:

    RUBBER MOLD RELEASE APPLICATION: Dilute this product; one-part McLube to four-parts water is suggested while a mold is being conditioned. Depending on the process and material used, it may be possible to further dilute the product. McLube 1829 is considered a stable emulsion, but we recommend gentle agitation before use and periodically during application. The diluted product can be sprayed or wiped onto the mold surface. Apply the product to a hot mold to facilitate evaporation and save time.

    APPLICATION TO UNCURED RUBBER: Apply to the rubber while it is hot. If the surface is not hot enough to dry the coating quickly, then use hot air or heat lamps. Apply by spraying, flow coating or dipping. The optimum dilution rate will depend on the compound or process involved. Preliminary evaluations will determine the lowest concentration possible without reducing effectiveness.

Safety and Handling:

    Review the Safety Data Sheet before using this product. McLube 1829 has a very low order of toxicity but good industrial practice dictates caution at all times. Safety glasses and gloves are recommended when using this product. Prolonged contact with the skin should be avoided. Keep the product from freezing.
