  • Best Practices for Dow 3-7509 Silicone Insulating Glass Sealant

    *See Terms of Use Below

    1. Surface Preparation

      Before using this product, clean all surfaces, removing all foreign matter and contaminants, such as grease, oil, dust, water, frost, surface dirt, old sealants or glazing compounds and protective coatings. Clean all surfaces by mechanical or solvent procedures. Always wipe solvents on and off with clean, oil- and lint-free cloths.

      Follow solvent manufacturer’s recommended safe handling instructions and applicable federal, state and local laws.

    2. Testing

      Dow Corning recommends several in-house quality control tests to ensure optimum sealant performance. These tests include: Cure test to ensure expected sealant cure rate.

      Tab adhesion tests to ensure proper sealant adhesion to production surfaces.

      These tests should be performed every time sealant batches are changed. Specific procedures for these recommended tests can be supplied by Dow Corning.
