General description

Silicone oil is a liquid based siloxane that is part of the methyl silicone fluid system. It has a viscosity of 500 cSt that is dependent on the chain length distribution. Its refractive index is ~ 1.402 and dielectric strength is ~ 14 kV/mm. It′s surface tension tends to increase with an increase in the viscosity.

Application

Silicone oil can be used for a variety of application such as: heat transferring medium in chemical and petrochemical industries, a dielectric coolant, a lubricant and antiflatulent agent, protective coatings for construction materials, a cosmetic additive.

Poly(dimethylsiloxane) (PDMS) materials have been extensively shown to function as excellent fouling-release (FR) coatings in the marine environment. The incorporation of biocide moieties, such as quaternary ammonium salts (QAS), can impart additional antibiofouling properties to PDMS-based FR coating systems. In
