Hydrophobic Fumed Silica LC-HFS300

LC-HFS300 is a hydrophobic fumed silica based on hydrophilic white carbon black with a specific surface area of 200, treated with special silicone oil, and structured. Mainly used for anti settling in coatings and inks, thickening in resins and adhesives, and weak organic silicon materials.

Features & Benefits of Hydrophobic Fumed Silica LC-HFS300

In highly transparent MS and silicone adhesives, it provides thickening and reinforcement properties to avoid the decrease in transparency caused by the addition of fillers.
It exhibits excellent dispersibility and anti settling function in the coating, avoiding particles and pitting on the surface of the coating.
Provide excellent reinforcement performance in adhesives and silicone materials.
It exhibits excellent anti settling effect in coatings and inks, providing high thixotropy and low viscosity increase.
