Supreme Silicones Antifoam Compounds are designed to provide optimum Antifoam performance combined with good foam knock down performance. SS-ASO is Activated Silicone Oil in various viscosities having unique combination of properties, which give superior performance in a variety of applications. They are Translucent in color, odorless and inert in nature. Manufactured in the viscosity range from 800 cps to 3500 cps by using Poly Dimethyl Siloxane and Silicon Dioxide (SiO2) powder.

Intermediate viscosity grades are also available upon request. Mostly used in preparation of Antifoam / Defoamer Emulsions.

If required, Supreme Silicones will provide emulsification process along with emulsifier.
