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. Dimethicone is used in the active silicone fluid in automotive viscous limited slip differentials and couplings. SpletTools Sodium methylsulfinylmethylide (also called NaDMSO or dimsyl sodium) is the sodium salt of the conjugate base of dimethyl sulfoxide. This unusual salt has some uses in organic chemistry as a base and nucleophile . Since the first publication in 1965 by Corey et al., [2] a number of additional uses for this reagent have been identified. [3] geeky medics pulmonary oedema
