Product Description
Momentive RTV108Q – Versatile, one-component silicone sealant for industrial applications
Momentive RTV108 is a one-component, ready-to-use silicone sealant from the renowned RTV 100 series. This versatile sealant cures at room temperature upon contact with atmospheric moisture, 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 immediately and easy to apply.
- Room temperature hardening: Hardens at ambient temperature without additional hardener, through humidity.
- Self-adhesive: Good adhesion to various materials without an additional primer.
- Flexible at low temperatures: Retains elasticity even in cold conditions.
- Excellent durability: Offers high resistance to weathering, ozone and chemicals.
- Electrical insulation: Very good electrical insulation properties, ideal for electronic applications.
Typical application areas:
- Seals and gaskets: Ideal for applications requiring 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 in applications requiring weather resistance.
Technical specifications:
- Color: Clear
- Temperature resistance: Resistant to low and high temperatures as standard.
- 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; for safety, users should follow OEM and AMM guidelines.)
