- 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.
