Highly spherical silica particles ensure excellent flowability and uniform dispersion in coating systems.
Controlled particle size distribution (D50 ≈ 2.5–3.0 µm) delivers consistent, fine matte finish without compromising surface smoothness.
Surface-treated with dimethicone for enhanced compatibility with solvent-based and high-solids resin systems.
Low oil absorption (~180 g/100g) minimizes viscosity increase and supports high loading levels in formulations.
Thermally stable up to 300°C, enabling use in baking finishes and high-temperature curing processes.
Automotive clearcoats and basecoats requiring durable, low-gloss aesthetic control.
Industrial maintenance coatings for machinery, metal furniture, and architectural steel.
UV-curable wood coatings where haze-free matting and rapid cure response are critical.
Plastic coatings for electronics housings and consumer appliances demanding scratch-resistant matte surfaces.
