Description

General description

Silicone oil is low viscosity liquid polymerized siloxanes with organic side chains.

Application

Low viscosity silicone oil has been used to prepare cellulose based electrorheological particles for medical devices. The diffusive behavior of spreading of a silicone oil polymer on solid surfaces was studied. It was also used to investigate Marangoni flow, induced by two liquid droplets on a solid surface, exposed in air. Many diverse applications of silicone oil are as heat exchangers, hydrophobic coating of glass, ceramics, textiles and leathers, component of salves.
