Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, is a silicone polymer with a wide variety of uses, from cosmetics to industrial lubrication and passive daytime radiative cooling. [1] [2] [3] It is particularly known for its unusual rheological (or flow) properties.
Using this formulation, silicone grease is a translucent white viscous paste, with exact properties dependent on the type and proportion of the components. More specialized silicone greases are made from fluorinated silicones or, for low-temperature applications, PDMS containing some phenyl substituents in place
Polydimethylsiloxane is a prevalent siloxane. In organosilicon chemistry, a siloxane is an organic compound containing a functional group of two silicon atoms bound to an oxygen atom: Si−O−Si. The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H[OSiH 2] n OH and [OSiH 2] n. [1]
Polydimethylsiloxane (PDMS) is a typical release agent. A release agent (also mold release agent, release coating, or mold release coating) is a chemical used to prevent other materials from bonding to surfaces. Release agents aid in processes involving mold release, die-cast release, plastic release, adhesive release, and tire and web release. [1]
Chemical structure of the silicone polydimethylsiloxane (PDMS) Alfred Stock and Carl Somiesky examined the hydrolysis of dichlorosilane, a reaction that was proposed to initially give the monomer H 2 SiO: + + When the hydrolysis is performed by treating a solution of H 2 SiCl 2 in benzene with water, the product was determined to have the approximate formula [H 2 SiO] 6.
The PDMS stamp, in most applications, is a 10:1 ratio of silicone elastomer and a silicone elastomer curing agent. This mixture consists of a short hydrosilane crosslinker that contains a catalyst made from a platinum complex. After pouring, the PDMS is cured at elevated temperatures to create a solid polymer with elastomeric properties. The ...

Polydimethylsiloxane is a widely used antifoaming agent. Silicone-based defoamers are also suitable in non-aqueous foaming systems like crude oil and oil refining. For very demanding applications fluorosilicones may be suitable. EO/PO-based defoamers contain polyethylene glycol and polypropylene glycol copolymers.
