Tygris TF8505 is a Silicone paste based on polydimethyl siloxane oil especially intended for use in industrial and laboratory lubrication applications. TF8505 is used as a high viscosity grease in the lubrication and assembly of taps, valves, elastomer seals and O-rings including applications working under vacuum. The high water repellent property of silicone paste gives excellent water washout resistance. Benefits: Very resistant to extreme temperatures of between - 50 C and + 200 C in continuous use and of over 200 C when exposed for short periods, Resistant to chemical agents: resists solvents - resists oxidation and remains unaltered by mineral and vegetable oils, Highly water repellent - resists very well to water wash out, Chemically inert; non corrosive on metals and no plasticising effect on rubbers or plastics. Very little variation in viscosity with fluctuations of temperature.
