African Utility Week

Cape Town, May 15, 2018

WACKER, the Munich-based chemical company, will make its debut at the 18th African Utility Week (AUW) in Cape Town, South Africa, by introducing several high performance silicones for the transmission and distribution industry. Product highlights include the silicone rubber compound POWERSIL® 310 MH as well as the silicone coatings POWERSIL® 552, POWERSIL® 567 and POWERSIL® 577 PLUS. African Utility Week, one of the leading trade shows for Africa’s power and energy professionals, takes place from May 15 to 17.

WACKER is exhibiting its POWERSIL® portfolio at the African Utility Week for the first time this year. “Africa has always been an interesting market for us with high potential, especially for the insulator business”, says Cyril Cisinski, Managing Director of Wacker Chemicals Middle East, who also heads the African region. The company’s business with local insulator manufacturers has grown rapidly in recent years. “The African Utility Week is a great chance for us to present our comprehensive expertise in high-quality silicone coatings for transmission and distribution applications.”

WACKER will introduce several POWERSIL® products at AUW, among them the peroxide curing silicone compound POWERSIL® 310 MH. The ready to use silicone cures to an electrically insulating, highly erosion resistant silicone rubber which can be used for all types of outdoor electrical insulating equipment such as composite insulators, arrester housings and bushings. It features superior tracking, erosion, and arc resistance and excellent mechanical and dielectric properties. Its hydrophobic, i.e. water-repellent surface reduces wetting and long term surface contamination, thus effectively preventing pollution flashovers. POWERSIL® 310 MH can be processed using injection, transfer or compression molding.

WACKER also presents its silicone coatings POWERSIL® 552, POWERSIL® 567 and POWERSIL® 577 PLUS. These products form a tough high voltage insulator coating after curing with very good dielectric, i.e. tracking and arc resistance properties. This makes them a cost-effective alternative for coating glass, porcelain and epoxy resin insulators. The water-repellent, highly hydrophobic silicone coating protects the insulator against flashovers and other damage caused by surface contamination. POWERSIL® 552 and POWERSIL® 567 are one component silicone dispersions, whereas POWERSIL® 577 PLUS is a curable silicone-in-water emulsion. All grades provide primerless adhesion to glass, porcelain and epoxy resins.
