PST-525 is a silicone lubricating compound that meets the requirements of the MIL-S-8660C specification and is part of the U.S. government’s Qualified Products List (QPL). This light-bodied silicone compound is comparable to Dow Corning 4 electrical insulating compound (DC-4) and to Novagard G624 dielectric silicone grease.
PST-525 silicone grease has operating temperature range of −70°F to 400°F and an unworked penetration in the 200 to 260 range with a typical value of 230. This silicone lubricating compound is moisture proof and water repellent, electrically insulating, non-corrosive, and low in volatility. PST-525 also has excellent thermal and chemical stability properties.
PST-507 silicone lubricating grease is used in applications that require conformance and certification to MIL-S-86660C requirements for non-melting, heat-stable silicone compounds. Moisture proofing, electrical insulation, and mechanical lubrication applications include:
PST-525 silicone lubricating grease is supplied in drums, plastic pails, jars, cartridges, and tubes. Private labeling and custom packaging are available to meet special requirements. Contact PolySi Technologies for more information.
