Silicone grease, sometimes called dielectric grease, is a waterproof grease made by combining a silicone oil with a thickener. Most commonly, the silicone oil is polydimethylsiloxane (PDMS) and the thickener is amorphous fumed silica. Using this formulation, silicone grease is a translucent white viscous paste, with exact properties dependent ...
The grease helps to prevent joints from "freezing", as well as ensuring high vacuum systems are properly sealed. Apiezon or similar hydrocarbon based greases are the cheapest, and most suitable for high vacuum applications. However, they dissolve in many organic solvents. This quality makes clean-up with pentane or hexanes trivial, but also ...
A silicone oil is any liquid polymerized siloxane with organic side chains. The most important member is polydimethylsiloxane . These polymers are of commercial interest because of their relatively high thermal stability and their lubricating properties.
Aqueous or solvent cleaning both have accepted methods to dispose of the "sludge" created. It has been reported that talcum powder can be used as an absorbent of cosmoline by packing the powder around the item to be cleaned and applying sufficient heat to melt the solid film, allowing the compound to be wicked from the coated surface into the ...
A US Patent was issued in 2001, [3] and the technology has since been licensed by other manufacturers of cleaning equipment. A number of manufacturers in the cleaning industry now produce and market spray-and-vac systems or systems that are similar, and approximately 40,000–50,000 units have been sold worldwide.
Regarding use of silicone grease on rotating contact. This is NOT an appropriate use for three reasons. a) As the author of the comment noted, the lubricating qualities of silicone grease may be insufficient. and b) rotating contacts may experience arcing at times. Silicone may convert to silicon carbide in the presence of electrical arcing.
Conformal coating spray booth. Spray coating can be completed with a spray aerosol or spray gun and is suitable for low- and medium-volume processing. The coating application may be limited due to 3D effects. The masking requirements have less penetration. This method can be used in spray booths for medium-scale production. [5]
Aqueous parts cleaning industrial washer. Parts cleaning is a step in various industrial processes, either as preparation for surface finishing or to safeguard delicate components. One such process, electroplating, is particularly sensitive to part cleanliness, as even thin layers of oil can hinder coating adhesion.
