Highly efficient matting agent based on spherical, fumed silica with controlled particle size distribution.
Excellent transparency and clarity retention in clear coatings and inks.
Superior storage stability and dispersion ease in solvent-borne, water-borne, and UV-curable systems.
Low dosage requirement—typically effective at 0.5–3.0 wt% depending on resin system and desired gloss level.
Non-aqueous surface treatment ensures compatibility with hydrophobic polymer matrices and minimizes viscosity impact.
Automotive clearcoats and OEM topcoats requiring uniform low-gloss appearance.
Architectural and industrial maintenance coatings for interior/exterior matte finishes.
UV-curable wood coatings and plastic coatings for furniture and decorative surfaces.
Specialty printing inks—including gravure and flexo—where high optical clarity and matte effect are critical.
High-performance powder coatings for appliances and metal substrates demanding consistent haze control.
