Momentive Performance Materials N-Sil® RTV128 Silicone Modified Alkoxy Adhesive Sealants, Translucent (discontinued **)
Categories:	Polymer; Adhesive; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade
Material Notes:	N-Sil® adhesive sealants are one-component, ready-to-use, and cure to a tough, resilient silicone rubber on exposure to atmospheric moisture at room temperature. Key Performance Properties: Primerless adhesion to many metals and plastics Non-corrosive to aluminum and steel per MIL-A-46146A+ Lower odor cure than conventional silicone sealants UL recognition (refer to GE Silicones Tech Info Sheet CDS4320 for additional information) One component Cures at room temperature Excellent electrical insulation properties Retains elastomeric properties at temperatures of -60°C(-75°F) to 204°C(500°F) for short periods Excellent weatherability, ozone and chemical resistance Applications: Typical applications include, but are not limited to, sealing vertical joints bonding dissimilar materials such as metal to plastic and glass to aluminum, electrical insulation of wires and terminals, and formed-in-place gasketing. GE Silicones became a part of Momentive Performance Materials in 2006.
