In the vast realm of organosilicon materials, water - soluble silicone oil IOTA - 1291 stands out with its unique properties and wide - ranging applications. It is a polyether - modified polydimethylsiloxane, a polymer that ingeniously combines hydrophilic organic compounds with hydrophobic polysiloxanes, endowing it with distinctive characteristics.

Outstanding Properties, Distinct Features

IOTA - 1291 is a special organosilicon surfactant with low surface tension. This property allows it to spread rapidly when in contact with other substances, effectively reducing interfacial resistance. It exhibits excellent hydrophilicity, being completely miscible with water in any proportion and also soluble in organic solvents such as ethanol and acetone. Additionally, it possesses antistatic, soft, smooth, and well - ventilated properties. In terms of physicochemical data, it appears as a colorless to light yellow transparent liquid. At 25℃, its specific gravity is 1.030, viscosity ranges from 500 to 1500 cst, refractive index is between 1.448 and 1.458, the cloud point of a 1% aqueous solution is 42℃, and the surface tension at 25℃ is 23 mN/m. The active ingredient content is above 99%.

Diverse Applications, Remarkable Effects

In the textile finishing industry, IOTA - 1291 plays a crucial role. Fabrics treated with it become soft, smooth, and comfortable to wear. They also have good stiffness and dimensional stability, reducing the likelihood of wrinkling and deformation. In personal care products, its good water solubility and surface activity enable it to form a uniform and breathable protective film on the skin, facilitating easy combing in both dry and wet conditions. In the leather industry, it is a key component of leather smoothening and finishing agents, giving various leather surfaces a smooth, shiny, and soft feel. In water - based coatings, acrylic adhesives, and inks, it can improve the flowability of the systems, resulting in a flat and shiny product surface.
