IOTA 201-1 Octamethyltrisiloxane

IOTA 201-1 Octamethyltrisiloxane
Description and Application

IOTA 201-1CST Pure Silicone Fluid is a 100% linear Polydimethylsiloxane composed mainly of Octamethyltrisiloxane (CAS#107‐51‐7) with a viscosity of 1cSt @ 25°C. The fluid is clear, colorless and essentially odorless.

IOTA 201-1CST Pure Silicone Fluid is characterized by its low viscosity, high rate of evaporation, low pour point (‐100°C), low VTC (viscosity change at temperature), low surface tension (high spreadability), and good lubrication. In closed systems, it is an low temperature bath fluid and low temperature heat transfer fluid.

IOTA 201-1CST Pure Silicone Fluid (Trisiloxane) is also used in a number of personal  care products due to its good spreading and unique evaporation 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.
