Applications
Designed for applications which demand a strong but flexible bond, such as when bonding materials with differing thermal expansion rates, e.g. glass to metal or glass to plastic.
Unprimed adhesion to commonly used materials including enameled and painted steel, aluminum, ceramic and glass as well as to certain plastics used in engineering applications.
Used as a Formed-in-Place Gasket (FIPG) material.

How to Use
Substrate Preparation
All surfaces must be clean and dry. Degrease and wash off any contaminants that could impair adhesion. S Good unprimed adhesion may be obtained on a variety of substrates, including enameled and painted steel, aluminum, ceramic, glass and certain plastics. Substrates to which good adhesion is normally not obtained include PTFE, polyethylene, polypropylene and related materials. For maximum adhesion, the use of DOWSIL™ 1200 OS Primer is recommended. After solvent cleaning apply a thin coat of DOWSIL™ 1200 OS Primer by dipping, brushing or spraying. Allow primer to dry for 15 to 90 minutes at room temperature and a relative humidity of 50% or higher.
How to Apply
Apply a bead of DOWSIL™ 7091 Adhesive Sealant (see Handling Precautions) to one of the prepared surfaces, then quickly cover with the other substrate to be bonded. On exposure to moisture, the freshly applied material will "skin-over" in about 10-15 minutes at room temperature and 50% relative humidity. Any tooling should be completed before this skin forms. The surface is easily tooled with a spatula. The adhesive/sealant will be tack-free in approximately 30 minutes.
Cure Time
After skin formation, cure continues inward from the surface. In 24 hours (at room temperature and 50% relative humidity) DOWSIL™ 7091 Adhesive Sealant will cure to a depth of about 2 mm. Very deep sections, especially when access to atmospheric moisture is restricted, will take longer to cure completely. Cure time is extended at lower humidity levels. Before handling and packaging bonded components, users are advised to wait a sufficiently long time to ensure that the integrity of the adhesive seal is not affected. This will depend on many factors and should be determined by the user for each specific application.
