Product Information
Dow Corning® 7091
Adhesive/Sealant
FEATURES
•One-component adhesive/alant •Cures at room temperature when expod to moisture in the air •Alkoxy cure system
•Non-sag, paste consistency •Easy to apply
•Cures to a tough, flexible rubber •Excellent adhesion to many substrates
•Stable and flexible from -40°C (-40°F) to +180°C (+356°F)
High performance neutral cure silicone adhesive/alant 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 ud materials including enamelled and painted steel, aluminum, ceramic and glass as well as to certain plastics ud in engineering applications.
•Ud as a Formed-in-Place Gasket (FIPG) material.

HOW TO USE
Substrate preparation
All surfaces must be clean and dry.
花猫的拼音Degrea and wash off any
contaminants that could impair
adhesion. Suitable solvents include
isopropyl alcohol, acetone or methyl
ethyl ketone.
Good unprimed adhesion may be
obtained on a variety of substrates,
including enamelled 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 u of Dow Corning ® 1200 OS Primer is recommended. After solvent c
leaning apply a thin coat of Dow Corning 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毒标语
Apply a bead of Dow Corning ® 7091 Adhesive/Sealant (e
Handling Precautions) to one of the prepared surfaces, then quickly cover with the other substrate to be bonded.
On exposure to moisture, the
入党介绍人讲话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/alant 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) Dow Corning 7091
Adhesive/Sealant will cure to a depth of about 2mm. Very deep ctions, 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, urs are advid to wait a
sufficiently long time to ensure that the integrity of the adhesive al is not affected. This will depend on many factors and should be determined by the ur for each specific application.
HANDLING PRECAUTIONS
When using solvents avoid contact with skin and eyes, heat, sparks and open flames. Always provide adequate ventilation. Obtain and
follow handling precautions from the solvent supplier.
Product safety information required for safe u is not included. Before handling, read product and safety data sheets and container labels for safe u, physical and health hazard information. The material safety data sheet is available on the Dow Corning Web site at
