XYSIL® fumed silica is mainly used in paints and coatings as a thixotropic agent and anti-settling agent.
It is used to control rheological characteristics, helps in the prevention of rust and corrosion. XYSIL® products should be added in concentrations of 0.5–5.0%.
XYSIL® fumed silica improves the thixotropic and rheological properties of coatings and paint systems, retains original transparency of lacquers. Furthermore, the addition of fumed silica enhances the hardening of the coating film, adhesion to surfaces, as well as reduces the deterioration rate of the coatings and fading of materials with transparent top coating. Besides, it helps to prevent run-off and sag of paints applied on vertical surfaces, thus ensuring top quality leveling. The fumed silica is used as a matting agent of lacquer systems, whereas the desired effect may be adjusted within wide ranges.
