Application Instructions


  • Dow 111 Silicone Tube Valve Lubricant can be applied by hand, specially designed automated equipment, brushing or wiping. Certain designs of grease guns may seize up; test prior to use.
  • A thinner consistency can be achieved by dispersing in solvents such as xylene, mineral spirits and Methyl Ethyl Ketone (2-Butanone). Dow 111 Silicone Lubricant can then be applied by brushing, dipping or spraying.
  • Dow 111 Silicone Lubricant should not be applied to any surface which 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.
