MOLYKOTE® High Vacuum Grease

DuPont MOLYKOTE® High Vacuum Grease is a premium lubricant solution formulated from a high purity silicone oil and exhibiting a very low volatility. MOLYKOTE® High Vacuum Grease is engineered for use in plastic-on-metal or rubber-on-metal components with excellent resistance for chemicals, water and extreme temperature exposure. Seals and prevents freezing of stopcocks and ground-glass joints in high-vacuum systems at pressures less than 10-6 mm Hg. Heat stable (-40 to 260 °C), low vapor pressure, and chemically resistant.

Features:

• Seals and lubricates chemical processing equipment
• Lubricating plug valves, control valves, flow meter bearings, ceramic plug cocks, fire extinguisher valves, water treating equipment, synthetic rubber gaskets and seals in high temperature applications
• Sealing vacuum and pressure systems
• Lubricating o-rings in binoculars and telescopes
• Prevents fogging of delicate lenses
• Reduces wear in plastic-to-metal and rubber-to-metal contact
• Low volatility
• Insoluble in water, methanol, ethanol, acetone, glycol and glycerine
• Can be dispersed in kerosene, stoddard solvent, benzene, toluene, ethyl ether or petroleum ether
• Unaffected by most vegetable and minerals oils, many organic compounds, and most common gases. It is also resistant to most aqueous solutions of inorganic salts and to dilute acids and alkalies
