POWERSIL® 3100 MH

POWERSIL® 3100 MH silicone rubber is a one-component, addition-curing compound that is ready to use and cures to an electrically insulating, highly erosion-resistant silicone elastomer. This product offers comparatively fast curing times compared to conventional silicone rubber, reducing cure times by 30-50%, depending on the wall thickness of the application, as well as the available machinery and runner system. Furthermore, no peroxide decomposition products are released during the curing process, reducing any potential hazards. The curing system also eliminates the risk of curing inhibition by oxygen.

Application Details

POWERSIL® 3100 MH is the addition curing silicone rubber of choice to manufacture all types of electrical insulating equipment for outdoor use, especially all types of composite insulators, arrester housings, bushings etc.

Processing

POWERSIL® 3100 MH cures rapidly at an elevated mold temperature (> 140 °C). It is designed to be used with sophisticated injection molding machines and molds. To achieve a good bonding between the typically used materials for electrical insulating equiment and POWERSIL® 3100 MH the primer G 800 should be used. It is available from Wacker Chemie AG as well. The used catalyst system can be deactivated by the influence of some chemical products (e.g. amine derivates, sulfur products, tin compounds and phosphorous products). Please avoid contact to these chemical products.
