Masil SF 5 is a Polydimethylsiloxane. Polydimethylsiloxane fluids have a viscosity designated within the product name. It is commonly referred to as Dimethyl fluid or Dimethicone. Polydimethylsiloxanes are non-corrosive, heat stable, and resistant to oxidation.
Dimethyl fluids are nonpolar and insoluble in water or the lower alcohols. They are completely miscible in aliphatic and aromatic solvents, including halogenated solvents. However, they are only partially soluble in the intermediate petroleum fractions, such as the naphthenes. Dimethyl fluids are insoluble in higher hydrocarbons, lube oils, waxes, fatty acids, vegetable oils, and animal oils.
