Product Description

 

This product is made by reacting common hydrophilic silica with a silane coupling agent under suitable conditions. It is a solid powdery silica with polysiloxane grafted on its surface. Its hydrophobic contact angle can range from 70 to 150 degrees. It not only has good hydrophobicity but also features a defoaming function. It is mainly used in fields such as textile printing and dyeing, defoamers, lubricating oils, and unsaturated polyester resins.
