Momentive RTV 157 & 159

Momentive RTV157 & RTV159

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:

• 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

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.

Potential applications:

• Aviation: Interior adhesives and sealants for aviation

• Aviation: Exterior adhesives and sealants for aviation

• Aviation: Wing and fuel sealants

• Aerospace

• Gaskets

• MIL SPEC

RTV157 silicone adhesive sealant is able to withstand 400° F of continuous operating temperature. RTV157 and RTV159 sealants may be applied directly to clean or primed substrates. Where broad surfaces are to be mated, the sealant should be applied in a thin, less than 6mm (1/4 in.) diameter, bead or ribbon around the edge of the surface to be bonded.

RTV 159 is a one-component, ready-to-use, high strength silicone rubber adhesive sealant. It cures to a tough resilient silicone rubber on exposure to atmospheric moisture at room temperature. This silicone adhesive sealant can typically withstand 500° F of continuous operating temperature for extreme temperature demands.
