Material Notes:
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 strengthHigh temperature performanceLow temperature flexibilityOne-componentRoom temperature cureGeneral primerless adhesionExcellent electrical insulation propertiesExcellent weatherability, ozone, and chemical resistanceGE Silicones became a part of Momentive Performance Materials in 2006.
