Features Of Tosoh Nipsil E-220A Matte Powder

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

  2. Controlled particle size distribution (D50 ≈ 2.5 µm) delivers consistent, soft-touch matte finish without compromising clarity.

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

  4. Low oil absorption (~180 g/100g) enables high loading levels without viscosity spikes or sagging in vertical applications.

  5. Thermally stable up to 300°C, supporting baking-cure processes common in automotive and appliance coatings.

Typical Applications Of Tosoh Nipsil E-220A Matte Powder

  1. Automotive interior trim coatings requiring premium tactile feel and scratch resistance.

  2. Architectural and industrial maintenance coatings for low-sheen, durable finishes on metal and plastic substrates.

  3. UV-curable clearcoats for electronics housings and consumer appliances.

  4. High-performance powder coatings where uniform surface texture and minimal gloss variation are critical.

  5. Specialty inks and overprint varnishes demanding optical neutrality and mechanical robustness.
