Silicone grease is widely used as a temporary sealant and a lubricant for interconnecting ground glass joints, as is typically used in laboratory glassware.Although silicones are normally assumed to be chemically inert, several historically significant compounds have resulted from unintended reactions with silicones.
Two typical examples: Left – Krytox, a fluoroether-based grease; Right – a silicone-based high vacuum grease by Dow Corning. A thin layer of grease made for this application can be applied to the ground glass surfaces to be connected, and the inner joint is inserted into the outer joint such that the ground glass surfaces of each are next ...
A unique identifier is their CAS registry number, 60164-51-4. In addition to PFPE, Krytox grease also contains telomers of PTFE and in fact was designed as a liquid or grease form of PTFE. It is thermally stable, nonflammable (even in liquid oxygen ), and insoluble in water, acids, bases, and most organic solvents .
Dow Corning, Bay City. Dow Corning was formally established in 1943 as a joint venture between the American conglomerates Dow Chemical and Corning Glass to explore the potential of silicone and was a manufacturer of products for use by the U.S. military in World War II. The company began operating its first plant, in Midland, MI, in 1945. Dr. E.
This helps provide a good seal and prevents the joint from seizing, allowing the parts to be disassembled easily. Although the silicone grease used as a sealant and a lubricant for interconnecting ground glass joints is normally assumed to be chemically inert, some compounds have resulted from unintended reactions with silicones.

Grease is a solid or semisolid lubricant formed as a dispersion of thickening agents in a liquid lubricant. Grease generally consists of a soap emulsified with mineral or vegetable oil. A common feature of greases is that they possess high initial viscosities, which upon the application of shear, drop to give the effect of an oil-lubricated ...

The company was among the three largest chemical producers in the world in 2021. [2] It is the operating subsidiary of Dow Inc., a publicly traded holding company incorporated under Delaware law.
Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...
