Low Outgassing Silicone RTVs

ASTM E595 Compliant Pastes Adhesives

Momentive has a full range of advanced low outgassing silicone products that offer outstanding performance with minimal by-products, and meet low outgassing requirements for adhesives in crew capsules and satellites.

The low outgassing silicones are resistant to extreme temperatures, friction, abrasion and stress, and can provide protection against corrosives, water, oils and salts. They meet or exceed ASTM E595 testing standards established by NASA and the European Space Agency (ESA).

Potential Applications for Momentive’s Low Outgassing RTV Silicones include:

  • Solar arrays and optical equipment sealing
  • Cast in place heat shielding
  • Crew capsule applications
  • Thermal insulation of sensitive components
  • Protective coatings for critical equipment
  • Encapsulants & potting for high heat locations
  • Interior & exterior adhesives
  • Flexible composite coatings
