Matting Agent for Architectural Coatings
CAS Number: 7631-86-9
Matting agents for architectural coatings are finely divided precipitated or fumed silica particles that scatter light to reduce the gloss level of paint films to flat, matte, or eggshell finishes. They are specially surface-treated for easy dispersion in waterborne systems and to minimize impact on film transparency, hiding power, and scrub resistance. These additives enable precise gloss control in interior and exterior architectural coatings across all finish levels.
