| RTV 157 is a one component, ready-to-use, high strength silicone rubber adhesive sealant. It cures to tough resilient silicone rubber on exposure to atmospheric moisture at room temperature. RTV157 releases acetic acid as a by-product of cure. RTV157 sealant is a paste consistency product which can be applied to horizontal, vertical, and overhead surfaces in applications requiring high strength and temperature performance. Since this adhesive sealants utilizes a moisture cure system, it must not be used in thicknesses greater than 6mm(1/4in.). Where section depths exceed 6mm (1/4 in.), GE Silicones one-component, addition cure or two-component silicone rubber compounds are suggested. This sealant was not designed for and should not be used for applications intended for permanent implantation into the human body. Mechanical properties for specimen cured 3 days at 25°C and 50% relative humidity. Key Performance Properties: - High strength
- High temperature performance
- Low temperature flexibility
- One-component
- Room temperature cure
- General primerless adhesion
- Excellent electrical insulation properties
- Excellent weatherability, ozone, and chemical resistance
GE Silicones became a part of Momentive Performance Materials in 2006. |
