Abstract

This study investigates the role of various amorphous silica types as colloidal silica, fumed silica, silica gel and precipitated silica in paint and coating formulations. Each type exhibits unique structural and surface characteristics that contribute distinctly to coating performance. The influence on key functional properties such as matting efficiency, scratch resistance, rheological behavior, and corrosion protection is discussed here. Through comparative evaluation, the paper highlights how the careful selection and incorporation of these silica types can optimize both the aesthetic and protective functions of modern paints, offering valuable guidance for formulators aiming to enhance coating performance through tailored silica technologies.
