PST-511 is a stiff, tacky silicone grease that’s designed for applications where contacting surfaces are not under heavy load, but high temperatures are expected. This silicone lubricating grease is comparable to Dow Corning Molykote 111 valve lubricant (DC-111) and Dow Corning high-vacuum silicone grease. PST-511 is also an offset for Novagard G-661 silicone lubricant.
PST-511 silicone lubricating grease has an operating temperature range of −40°F to 400°F and an unworked penetration in the 230 to 270 range with a typical value of 250. This silicone grease is non-corrosive, does not separate, and exhibits excellent dispersion characteristics. PST-511 is also low in volatiles and has excellent stability.
PST-511 is useful as an electrical insulator, corrosion inhibitor, mold release, and general-purpose lubricant for metal, rubber, and plastic parts. Applications for this silicone lubricating grease include water faucet valves, high voltage connectors, rubber O-rings and seals, automotive ignitions, and underground electrical connections.
PST-511 silicone lubricating grease is supplied in drums, plastic pails, jars, cartridges, and plastic tubes. Private labeling and custom packaging are available to meet special requirements. Contact PolySi Technologies for more information.
