ELASTOSIL® R 3112 B US
ELASTOSIL® R 3112 B US is one side of a two component, heat vulcanizing silicone rubber adhesive. ELASTOSIL® R 3112 B US is used primarily for fast bonding of vulcanized silicone rubber to itself. Especially in the case of larger flat shapes.
ELASTOSIL® R 3112 B US and C needs to be mixed at a ratio of 100:1, C:B. Before gluing, the surfaces should be cleaned with a solvent, e.g. chemically pure Acetone. After thoroughly mixing of the component C with component B the silicone adhesive should be applied in a thin layer. After fixing the parts under low pressure the vulcanization occurs at a temperature of 340°F (170 °C). The vulcanization time depends on the heat transfer of the parts, but the bonded area is vulcanized in approx. 30 sec. after reaching 340 °F. The adhesion will be improved by post curing.
ELASTOSIL® R 3112 B US Silicone Rubber Compound is designed specifically for use in high voltage applications. Suspension and line post insulators and surge arrestors molded from ELASTOSIL® R 3112 B US possess excellent resistance to arcing and tracking, increasing the reliability and reducing power interruptions.
