Description

Poly(Dimethylsiloxane) Ethoxylate/Propoxylate is a versatile silicone-based copolymer surfactant, known by the CAS number 68037-64-9. This compound is engineered to provide superior wetting, leveling, and foam control properties by combining the hydrophobic nature of polydimethylsiloxane with the hydrophilic character of polyether (EO/PO) chains. It is an essential additive for formulators in the coatings, personal care, and textile industries seeking to enhance product performance and process efficiency.

Application

• As a high-performance defoamer and air release agent in water-based paints, coatings, and adhesive formulations.
• As a key surfactant and emulsifier in personal care products like shampoos, conditioners, and skin creams for improved texture and spreadability.
• As a leveling and flow control agent in industrial and architectural coatings to eliminate surface defects and ensure a smooth finish.
• As a lubricant and softening agent in textile processing and fiber manufacturing.
• As a wetting and dispersing aid for pigments and fillers in various composite and plastic masterbatch systems.
• As a process aid and internal lubricant in polyurethane foam production and other polymer processing applications.
