Dow Corning 730 Solvent Resistant Sealant
Dow Corning 730 Solvent Resistant Sealant is a ready-to-use, solventless, nonslumping fluorosilicone rubber paste that reacts with moisture in the air to form a tough, rubbery solid. It is a fluid-resistant material that is ideally suited for use in many applications where resistance to fumes, splash, and sometimes even total immersion in fuels, oils and solvents is needed. Dow Corning 730 Solvent Resistant Sealant features good resistance to weathering, vibration, moisture, ozone, and temperature extremes. It retains its flexibility over a wide temperature range from -85 to 500°F (-65 to 260°C). Dow Corning 730 Solvent Resistant Sealant can be applied overhead or on vertical surfaces without fear of sagging, slumping or running off.
HOW TO USE
Dow Corning 730 Solvent Resistant Sealant is supplied ready to use. Under pressure, it flows readily from its container. The paste-like consistency makes it easy to work; a spatula or wooden paddle can be used for tooling the surface.
Dow Corning 730 Solvent Resistant Sealant cures inward from the surface. At conditions of 75°F (24°C) and 50 percent relative humidity, the sealant forms a skin within 10 minutes. Tooling is not practical after the skin begins forming. Alternate periods of application and tooling may be required.
STORAGE AND SHELF LIFE
Since moisture in the air will cause the sealant to cure, containers should always be sealed when not in use. Once a container has been opened, a plug of cured sealant may form in the nozzle or tube tip during storage. This is easily removed and does not affect the remaining material.
Dow Corning 730 Solvent Resistant Sealant is not recommended:
Dow Corning 730 Solvent Resistant Sealant is used primarily for bonding, sealing and caulking applications where resistance to the swelling effects of fuels, oils and solvents is needed. It can be used for assembling and/or repairing the fuel lines and tanks of cars, small engines, aircraft and rockets. Other potential applications include:
