Product Overview

About Fumed Silica

Created through high-temperature processing to form an ultra-fine, high-surface-area silica, Fumed Silica provides strong rheology control, thixotropy, suspension stability and reinforcement across high-performance formulations. Its extremely fine particle structure forms a three-dimensional network within liquid systems, helping control flow, prevent settling and improve sag resistance. In coatings, adhesives, inks and construction chemical systems, it supports formulation stability, while in polymer and cosmetic applications it can contribute to reinforcement, texture and consistency.
