  • Best Practices for Dow SR-7010

    *See Terms of Use Below

    1. Surface Preparation

      Surfaces should be clean and dry. Recommended cleaning methods include Dow Corning® brand OS Fluids, naphtha, mineral spirits, methyl ethyl ketone (MEK) or other suitable solvent. Rougher surfaces tend to promote adhesion of silicones to other surfaces.

    2. Application

      These products are also compatible with commercially available equipment and industry standard processes. These materials can be dispensed or molded depending on the product and application.

    3. Clean-Up

      Dow Corning OS Fluids are recommended to clean cured or uncured silicone residue from application equipment.

    4. Testing

      If a substrate or material is questionable with respect to potentially causing inhibition of cure, it is recommended that a small scale compatibility test be run to ascertain suitability in a given application. The presence of liquid or uncured product at the interface between the questionable substrate and the cured silicone indicates incompatibility and inhibition of cure.
