AS1821, 310ML

AS1821 is a non-corrosive, neutral cure, 1-part, RTV (room temperature vulcanizing) silicone adhesive sealant (electronic grade). It is one in a range of acetone cure products which are solvent free. It exhibits excellent primerless adhesion to many substrates and cures rapidly 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. Applications include shallow potting of electrical connectors in automotive.
