| 1084G is a non-corrosive, 1-part, room temperature vulcanising (RTV) silicone rubber. It is one of a new family of products called acetone cure sealants that are solvent free. It exhibits excellent primerless adhesion to many substrates. The product is cured rapidly in contact with atmospheric moisture to a tough rubber. It does not corrode copper or its alloys and exhibits excellent primerless adhesion when fully cured. Key Features: Excellent thermal conductivity Non corrosive Fast skinning Low linear shrinkage&& |
