Silicone Oil (All Viscosity) Silicone Oil is a water clear silicone fluid available in viscosities ranging from 0.65 centistokes to 1, 00, 000 centistokes. Important features of fluid include: – Little change in physical properties over a wide temperature span…a relative flat viscosity temperature slope and serviceability from — 40 to over 400°F (-40 to 204°C). Excellent water repellency. Good dielectric properties over a wide range of temperature and frequencies. Low surface tension – readily wets clean surfaces to impart water repellency and release characteristics. Low –toxicity – tests have established that SILICONE OIL is essentially Nontoxic and non-irritating (although temporary discomfort may result if rubbed into the eye). Silicone Oil also exhibits heat stability, oxidation resistance, very low vapour pressure, and high flash points. It is insoluble in organic liquid other than active solvents and is non-greasy, non-rancidifying and virtually odourless. Solubility: The solubility of SILICONE OIL varies somewhat according to the viscosity chosen. The low viscosity grade are more completely soluble in a given solvent than are the higher viscosity grades. Since solubility varies, testing is recommended before attempting volume operations. Solubility of the silicone fluid in a number or commonly-used solvents is indicated below. Flammability and toxicity should also be important considerations in the choice of a solvent.
