  • Best Practices for Dupont Molykote 4 Electrical Insulating Compound

    *See Terms of Use Below

    1. Surface Preparation

      MOLYKOTE® 4 Electrical Insulating Compound should not be applied to any surface that will be painted or finished. Such coatings may not adhere to the silicone-treated surface. If contaminated by a silicone coating, parts can be wiped or washed with solvent, washed with detergent, or immersed in an alcoholic potassium hydroxide solution and then rinsed in clear water before painting.

    2. Application

      MOLYKOTE® 4 Electrical Insulating Compound can be applied by hand, specially designed automated equipment, brushing or wiping. Certain designs of grease guns may seize up with silicone compounds

      test prior to use.

      A thinner consistency can be achieved by dispersing in solvents such as xylene, mineral spirits and methyl ethyl ketone. MOLYKOTE® 4 Electrical Insulating Compound can then be applied by brushing, dipping or spraying.

    3. Testing

      As each application may vary in chemical composition, pressure, flow velocity, relubrication requirements and equipment design, it is recommended that MOLYKOTE® 4 Electrical Insulating Compound be tested before adopting for regular use.
