    Shelf Life Details Shelf Life at 77°F (25°C) and 50 percent Relative Humidity, Because Dow Corning 236 Dispersion Coating cures to a rubbery mass on exposure to humid air, storage containers should be kept closed when not in use. The recommended procedure is to remove the quantity needed for a single application and keep the remaining material in a closed container. Store below 90°F (32°C). Dow Corning 236 Dispersion Coating has a shelf life of 12 months from date of manufacture. Refer to product packaging for “Use By” date.

  • Best Practices for Dow 236 Dispersion Coating

    *See Terms of Use Below

    1. Surface Preparation

      Surfaces must be clean and dry before curing. Moisture, grease, oil, dirt and cleaning agents can interfere with adhesion of the coating. Clean the surface with a solvent to remove foreign material. Then wash with Dow Corning ® OS Fluid or acetone to remove moisture and any residue from the first cleaning operation. In general, solvent cleaning of wood surfaces is not necessary. For best adhesion, apply a light, uniform coating of Dow Corning ® 1200 Prime Coat by brushing or spraying. Allow the prime coat to dry for 45 minutes at normal temperature and humidity conditions. Avoid excess prime coat. Light, uniform application is best. A low-VOC primer version is available as Dow Corning ® P5200 Adhesion Promoter.

    2. Application

      For precise control of coating thickness, spraying is the best method of application. However, brushing, dipping, roller coating or stamp coating may be used. To obtain the viscosity most suited to a particular spraying system, the dispersion may be thinned with a solvent such as VM&P naphtha or Dow Corning OS Fluid.

    3. Curing

      Apply Dow Corning 236 Dispersion Coating and allow to air-dry 24 hours at room temperature in a humid atmosphere, such as =50 percent relative humidity.

    4. Clean-Up

      To keep the dispersion from setting up and curing in spray guns, brushes, lines or rollers, thoroughly clean the application equipment immediately after use with a solvent such as Dow Corning OS Fluid.
