CHT AS1723 RTV, silicone adhesive sealant
Categories:	Polymer; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade
Material Notes:	Description: This is a non-corrosive, neutral cure, 1-part, RTV (Room Temperature Vulcanizing) silicone adhesive sealant. It is one in a range of Alkoxy cure products which are solvent free. It exhibits excellent primerless adhesion to many substrates and cures at room temperature when in contact with atmospheric moisture to form a tough rubber. This product will not corrode copper or its alloys and is suitable for use with electronic components. Key Features Self leveling Low odor Non corrosive Suitable for sensitive substrates Application: Suitable for sensitive substrates Information provided by CHT Group
