- Application Details
POWERSIL® 464 A/B is suitable for production of electrically conductive injection molded articles, especially cable accessories in the medium and high voltage range. Due to a special formulation good bonding of RTV-2 / LSR rubber onto non-post-cured premolded parts of POWERSIL® 464 A/B can be achieved. The higher possible the cure temperature of RTV-2 / LSR rubber the better will be the bonding. Post curing of the whole part additionally improves adhesion.
Processing
Components A and B are delivered ready to use in drums of 20 and 200 liters capacity. They can be pumped by means of standard metering equipment from these drums and mixing in a static mixer straight into the heated mold. The mixing ratio is 1 : 1. At room temperature, mixtures of A and B components have a pot life of at least three days.
