RTV157 | RTV159 | High-Temperature Silicone Adhesive Sealant

HEAT RESISTANCE, EXCEPTIONAL DURABILITY

Our RTV157 and RTV159 silicone rubber adhesive sealants are principally used by customers in the aerospace and aviation industries to secure and maintain the integrity of airframes and cabins. As one of the strongest high-temperature silicone sealants available, these one-component, ready-to-use, silicone rubber adhesives can provide the performance these industries require.

RTV157 and RTV159 silicone adhesive sealants have a paste consistency that can typically be applied to horizontal, vertical and overhead surfaces. They offer a reliable seal for applications requiring high strength and temperature performance. These adhesive sealants release acetic acid vapors as a byproduct of their cure. Review the technical documents and Key Features and Typical Benefits sections to see how our high-strength RTV157 and RTV159 sealants can benefit your project.

More About RTV157 and RTV159 Silicone Adhesive Sealants

RTV157 and RTV159 silicone adhesive sealants are acetoxy room-temperature-curing, one-component adhesives. They are generally ready to use and exhibit extremely high strength and heat resistance. RTV157 and RTV159 typically cure to tough, resilient silicone rubber on exposure to atmospheric moisture at room temperature, and are known for their high-temperature performance.

RTV157 silicone adhesive sealant is able to withstand 400° F of continuous operating temperature.
RTV159 silicone adhesive sealant can typically withstand 500° F of continuous operating temperature for extreme temperature demands.

Key Features and Typical Benefits of RTV157 and RTV159

High-strength rubber sealant
Reliable, high-temperature performance
Low-temperature flexibility
One-component sealant
Room-temperature cure
Primer-less adhesion to a range of substrates
Excellent electrical insulation properties
Excellent weatherability, ozone, and chemical resistance

While our RTV157 and RTV159 sealants are generally to serve in a broad range of industrial applications, they are more commonly used for aviation applications, such as bonding the light housing on the outside of airplanes. These high-temperature silicone adhesives have the capability to withstand high heat from aerospace lighting. They can also provide the high-strength seals to necessary to survive the wind shear on the outside of a plane.

Where section depths exceed 6 mm (1/4 in.), Momentive's one-component addition cure or two-component silicone rubber compounds are recommended. Additionally, these grades offer excellent electrical insulation properties, low temperature flexibility, and outstanding weatherability, as well as ozone and chemical resistance.
