RTV Silicone and Hardcoat Products for Aerospace

For more than 60 years, Momentive has helped power the aerospace journey. Momentive’s silicone products are integral to the assembly and operation of aircraft, spacecraft and military platforms. Our silicones were in the boots of the first astronaut to walk on the moon and the window seals of the Apollo capsules. We are proud to have been part of every U.S. manned space flight since then.

Momentive uses the experience from thousands of hours of flight and in-space time, to develop new products that help our customers continue the aerospace legacy. Our dedicated aerospace team is made up of highly experienced chemists and application development engineers located at application development centers around the world.
