Dimethyl siloxane
It is one of several types of silicone oil (polymerized siloxane). Its applications range from contact lenses and medical devices to elastomers ; it is also present in shampoos (as it makes hair shiny and slippery ), food ( antifoaming agent ), caulk , lubricants and heat-resistant tiles . See more Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, belongs to a group of polymeric organosilicon compounds that are commonly referred to as silicones and siloxane. … See more PDMS is viscoelastic, meaning that at long flow times (or high temperatures), it acts like a viscous liquid, similar to honey. However, at short … See more Surfactants and antifoaming agents PDMS is a common surfactant and is a component of defoamers. PDMS, in a modified form, is used as an herbicide penetrant and is a critical ingredient in water-repelling coatings, such as Rain-X. Hydraulic fluids and … See more • Silicone • Cyclomethicone • Siloxane and other organosilicon compounds See more The chemical formula of PDMS is CH3[Si(CH3)2O]nSi(CH3)3, where n is the number of repeating monomer [Si(CH3)2O] units. Industrial synthesis can begin from dimethyldichlorosilane and … See more PDMS is hydrophobic. Plasma oxidation can be used to alter the surface chemistry, adding silanol (SiOH) groups to the surface. Atmospheric air plasma and argon plasma will work for this application.
