High-vacuum silicone grease have been designed for sealing and lubrication in vacuum and pressure applications. It is typically a stiff, non-melting silicone lubricating grease which maintains its consistency over a temperature range of -40 to 204ºC. High-vacuum grease is recommended for vacuum systems up to 10-6 mbar. It has a translucent white colour and a density of 1.1 g/cm3. Evaporation rate at 200ºC is in the 0.5-1% range. Silicone high vacuum grease has good resistance against mineral and vegetable oils, aqueous solutions of inorganic salts and diluted acids and alkali's. Available silicone high vacuum grease are Micro-Tec G4 in a 60 gram jar and Molykote / Dow Corning 976V in a 150 gram tube ( the brand name has changed to Molykote due to companies restructuring – no change in the formula/composition).
Due to the initial outgassing, it is recommended to pre-condition the grease under vacuum and operating temperature until the required vacuum level has been reached.

Typical applications include:

• seal and lubricate vacuum components
• seal and lubricate vacuum feedthroughs
• sealing glass desiccators and lubricate glass seals
• lubricate O-rings on microscopes
• lubricate and seal fine threads
• lubricate stop-cocks, plug valves. Control valves and flow meter bearings
• lubricate laboratory equipment
• lubricate synthetic rubber gaskets and seal in high-temperature applications
• protect seals in an aqueous environment
• corrosion protection
