Pure Silicone Fluid 1.5cSt is a super low‐viscosity (1.5cSt @ 25°C) Polydimethylsiloxane

that is composed of Decamethyltetrasiloxane (CAS#141‐62‐8). The fluid is clear,

colorless and odorless.   

PSF‐1.5cSt is characterized by its low viscosity (close to water), , high compressibility,

low surface tension (spreadability), excellent low temperature stability (pour point –

90°C), low viscosity change at extremely low temperatures and excellent lubricity.  Due

to its low temp stability, it is widely used as a low temperature bath fluid and low

temperature heat transfer fluid.   

PSF‐1.5cSt (Dimethicone) is also used in a number of Personal Care products due to its

excellent spreading and unique volatility characteristics. It features good solubility in

anhydrous alcohols and in a wide variety of solvents.  In addition, it leaves no residue or

build‐up, has a transient effect, and a non‐greasy feel.
