Achieve professional-quality sealing on a wide variety of substrates with Dow Corning® Silicone Glazing Sealant. This acetoxy-cure, RTV silicone sealant can be used for backlite replacement and skylight installations along with weatherstripping and gasket repair and general glazing applications.

Dow Corning Silicone Glazing Sealant forms a long-lasting, water-resistant seal that provides both high strength and high flexibility. Its high weather resistance and ±25% movement capability make it useful in applications exposed to the elements, including sunlight and a wide range of temperatures. Once cured, it forms a tough 100% silicone rubber seal that is resistant to cracks and shrinking.

Unique adhesion-optimized formulation

Specifically formulated to meet glass shop glazing needs, Dow Corning Silicone Glazing Sealant adheres to many common substrates, including most glass, plastic, metal, fiberglass and aluminum substrates along with repainted surfaces.

Easy installation

Dow Corning Silicone Glazing Sealant’s one-part formulation cures quickly, speeding up and simplifying installation. It is packaged with a convenient removable, resealable and reusable nozzle that allows the cartridge to be stored for the short term – saving both time and product. Additionally, the sealant’s longer working time means a professional appearance for the finished job.
