Material Notes:
RTV series one-component, ready-to-use adhesive sealants are extremely versatile. They cure to a tough, durable, resilient silicone rubber on exposure to atmospheric moisture at room temperature. Acetic acid vapors are released from the sealant surface as a by-product of cure.RTV 112 and 118 sealants are self-leveling products which are preferable to paste-consistency sealants when flow into small crevices and hard to reach places is desired.Key Performance Properties: One-component productsCapability to cure at room temperature and ambient humiditySelf adhesion propertiesLow temperature flexibilityHigh temperature performanceExcellent weatherability and ozone and chemical resistanceExcellent electrical insulation propertiesApplications: Electrical insulation, thin section potting, self leveling protective coatings. Will flow into small crevices and hard to reach places.FDA 21 CFR 177.2600 USDA NSF International Std. No. 51GE Silicones became a part of Momentive Performance Materials in 2006.
