Ultra-fine, spherical fumed silica particles engineered for superior matting efficiency in clear coatings.
Low-density structure enables excellent suspension stability and reduced settling in solventborne and high-solids systems.
Surface-treated with dimethyldichlorosilane for enhanced hydrophobicity and improved compatibility with organic resins.
Consistent particle size distribution ensures reproducible haze control and uniform surface texture.
Low abrasivity minimizes wear on application equipment and maintains gloss retention in adjacent coated areas.
Automotive clearcoats requiring high clarity with controlled matte finish.
Architectural and industrial maintenance coatings for interior wood and metal substrates.
UV-curable inks and overprint varnishes used in premium packaging applications.
High-performance furniture finishes where scratch resistance and visual softness are critical.
Plastic coatings for consumer electronics housings and automotive interior trim.
