  • Best Practices for Dow OS-120

    *See Terms of Use Below

    1. Clean-Up

      Manual cleaning is accomplished by applying DOW CORNING OS120 Fluid directly to the part, then brushing or wiping. The fluid can also be applied to the brush or wipe for similar cleaning action. Once cleaning has been completed this product will dry rapidly at room temperature. DOW CORNING OS120 Fluid is compatible with a wide range of materials, and will not harm most substrates, including metals, plastics, and elastomeric materials. It is recommended that compatibility with specific materials be verified prior to production cleaning.
