Specific features of POWERSIL® 464 A/B

  • Electrically conductive

POWERSIL® 464 A/B is suitable for production of electrically conductive injection moulded 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.

Components A and B are delivered ready to use in drums of 20 and 200 litres 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.

For detailed information, refer to brochures on www.wacker.com.


The 'Best use before end' date of each batch is shown on the product label.

Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
