Tosoh Nipsil L-250 Matte Powder

Tosoh Nipsil L-250 Matte Powder is a high-purity, spherical silica additive from Tosoh’s Nipsil series, engineered for controlled matting and rheology modification in coatings, inks, and adhesives. Its low oil absorption and narrow particle size distribution ensure excellent dispersion, transparency retention, and consistent哑光 effect without sedimentation.

Features Of Tosoh Nipsil L-250 Matte Powder

  1. Highly spherical silica particles ensure excellent flowability and uniform dispersion in coating systems.

  2. Controlled particle size distribution (D50 ≈ 2.5–3.0 µm) delivers consistent, fine matte finish without compromising surface smoothness.

  3. Surface-treated with dimethicone for enhanced compatibility with solvent-based and high-solids resin systems.

  4. Low oil absorption (~180 g/100g) minimizes viscosity increase and supports high loading levels in formulations.

  5. Thermally stable up to 300°C, enabling use in baking finishes and high-temperature curing processes.

Typical Applications Of Tosoh Nipsil L-250 Matte Powder

  1. Automotive clearcoats and basecoats requiring durable, low-gloss aesthetic control.

  2. Industrial maintenance coatings for machinery, metal furniture, and architectural steel.

  3. UV-curable wood coatings where haze-free matting and rapid cure response are critical.

  4. Plastic coatings for electronics housings and consumer appliances demanding scratch-resistant matte surfaces.
