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. Apiezon, silicone-based, and fluoroether-based greases are all used commonly in laboratories for lubricating stopcocks and ground glass joints. The grease helps to prevent joints from "freezing", as well as ensuring high ...
The silicone polymers are often made by reacting dimethyl dichlorosilane with water. [4] Linear dimethylpolysiloxane polymer reaction. Fillers such as acetic acid can provide a fast cure time, while oxides and nitrides can provide better thermal conductivity. Tack-free times are typically on the order of minutes, with cure times on the order of ...

Thermal paste (also called thermal compound, thermal grease, thermal interface material (TIM), thermal gel, heat paste, heat sink compound, heat sink paste or CPU grease) is a thermally conductive (but usually not electrically conductive) chemical compound, which is commonly used as an interface between heat sinks and heat sources such as high ...
You may need some kind of grease to seal the joint. Graeme Bartlett 10:53, 7 May 2019 (UTC) Per Graeme, the addition of a non-reactive grease would be standard; there's a silicone-based grease which is industry-standard for this. See silicone grease where the article specifically mentions its use in sealing ground-glass joints. This served two ...
