Dowsil 7091 Silicone Adhesive & Sealant

Dowsil 7091 formerly Dow Corning 7091 is a non-sag, easy-to-apply silicone sealant that offers excellent adhesion to a variety of substrates.

This material is designed for applications that require a flexible but strong bond and is suitable for use as a Formed-in-Place Gasket (FIPG) material. RTV 7091 is commonly used on materials such as aluminum, glass, ceramic, enameled and painted steel, and certain plastics used in engineering applications.

When exposed to moisture in the air, the product will cure at room temperature forming a tough, flexible rubber. Remains flexible and stable from -55 to 180°C. When stored at or below 30°C in unopened containers, the usable life for this material is 12 months. The product is available in black, gray, and white.
