Model: high-temperature silicone sleeve 1. The product substrate using a special silicone. Nontoxic, slow aging can be repeatedly used 2. RTV silicone rubber component, low viscosity, solvent RTV silicone rubber 3. cured flexible insulation sealing, high temperature short time up to 350 4. The time of 30 minutes and also with acid, the acid copper plating bath silver plating solution does not swell. 5. The film is mainly used in chemical processes to break the hole and cover the hole, metal plastic coating, electrophoresis coating and electroplating block hole sealed to protect the threaded hole or threaded column, paint and chemical solution to prevent economic infiltration. Corrosion, acid, in contrast to conventional screwing with cost-saving labor costs and so on ...... very prominent advantage is a wise selection every smart company for sustainable development.
