CHT AS1623 RTV, silicone adhesive sealant
Categories:	Polymer; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade
Material Notes:	Description: This is a 1-part, RTV (Room Temperature Vulcanizing) silicone adhesive sealant. It is one in a range of Oxime cure products which are solvent free. It exhibits good primerless adhesion to many substrates especially plastics and cures rapidly at room temperature when in contact with atmospheric moisture. This product can be described as low corrosive but would not be recommended for use with copper or its associated alloys. Key Features High temperature resistance to +260°C/500°F Resistance to 315°C/599°F intermittent exposure Excellent flow and self leveling properties Good adhesion to many substrates Application: Applications include but are not limited to, sealing and fixing of domestic irons, shallow potting of electrical connectors for automotive applications. Cured Product: 7 days at 23+/-2°C and 50+/-5% humidity Information provided by CHT Group
