  • Best Practices for Dow Dowsil OS-20 Fluid

    1. Clean-Up

      Cleaning with Dow OS fluids is a simple process. Parts may be immersed in the cleaning fluid with vigorous action or the fluid can be applied by spray. Soils are lifted from the surfaces by the action of the fluid. Lightly contaminated components can be cleaned by wiping them with tissues impregnated with Dow OS fluids. Dow OS fluids are compatible with a wide range of materials and will not harm most substrates, including most plastics and delicate coatings. Their mild cleaning action also makes them suitable for cleaning multi-material components and devices. However, it is advisable to check the compatibility of Dow OS fluid with the surfaces to be cleaned. Dow OS fluids are excellent solvents for nonvolatile silicone materials. Contaminated surfaces that have been cleaned with Dow OS fluid can subsequently be coated or bonded because the Dow OS fluid will completely evaporate leaving no trace of silicone.
