Momentive RTV108Q – Versatile, single-component silicone sealant for industrial applications

Momentive RTV108 is a single-component, ready-to-use silicone sealant from the renowned RTV 100 series. This versatile sealant cures at room temperature upon contact with air humidity, forming a durable, elastic silicone rubber layer that is robust and weather-resistant. Ideal for demanding applications, RTV108 offers excellent resistance to weathering, chemicals, and ozone.

main advantages
  • Single-component formulation: Ready to use and easy to apply.
  • Room temperature curing: Cures at ambient temperature without additional hardener, due to air humidity.
  • Self-adhesive: Good adhesion to various materials without additional primer.
  • Flexible at low temperatures: Retains elasticity even in cold conditions.
  • Excellent resistance: Offers high resistance to weathering, ozone, and chemicals.
  • Electrical insulation: Excellent electrical insulation properties, ideal for electronic applications.
Typical areas of application:
  • Gaskets and seals: Ideal for applications that require a permanent seal, e.g., in the automotive and aerospace industries.
  • Electronic and electrical applications: Provides protection and insulation in electronic components and circuits.
  • Protection against environmental influences: Provides long-term protection for applications that require weather resistance.
Technical specifications:
  • Color: Clear
  • Temperature resistance: Standard resistance to low and high temperatures.
  • Certifications: Meets the requirements of US military standard MIL-A-46106 Group I Type I and Pratt & Whitney CML 09-001A. (Note: Specifications and certifications are subject to change; users should adhere to OEM and AMM guidelines for safety.)
