Features Of Tosoh Tosoh Nipsil K-500 Matte powder

  1. Highly spherical, micronized silica particles ensuring uniform dispersion and consistent matte effect.

  2. Low oil absorption for improved formulation efficiency and enhanced rheology control in solvent-based and high-solids systems.

  3. Surface-treated with dimethicone to provide excellent compatibility with silicone- and acrylic-based resins.

  4. Non-abrasive particle morphology preserves substrate integrity and coating gloss uniformity during application.

  5. Thermally stable up to 300°C, supporting curing processes in industrial coatings and adhesives.

Typical Applications Of Tosoh Tosoh Nipsil K-500 Matte powder

  1. Automotive clearcoats requiring controlled haze and scratch-resistant surface finish.

  2. Architectural and industrial maintenance coatings where low-sheen aesthetics and weather resistance are critical.

  3. UV-curable inks and overprint varnishes for packaging and premium labeling applications.

  4. High-performance silicone rubber compounds requiring reinforcement and anti-blocking functionality.

  5. Electronics encapsulants and conformal coatings needing dielectric stability and surface texture control.
