Momentive’s advanced RTV silicones are able to maintain critical properties for an extended time over the wide range of extreme temperatures typically encountered by aircraft and spacecraft. They remain flexible in extremely low temperatures and are thermally insulative. Our thermal protection systems are available in paste to flowable viscosity. In addition, our aerospace thermal coating systems offer low-outgassing and electrically dissipative formulations to accommodate a wide range of aerospace and defense applications.

Potential Applications of our Aerospace Thermal Coating RTVs

• Protective coatings and thermal insulation for sensitive components and critical equipment
• Encapsulants and potting for high-heat locations
• Interior and exterior adhesives
• Flexible composite coatings
• Cast-in-place heat shielding
• Adhesion of thermal blankets
