Features Of HOMSIL A370 Silica-based Matting Agent

  1. Highly efficient matting performance with excellent transparency retention in clear coatings.

  2. Superior dispersion stability in both solvent-borne and water-borne systems without excessive viscosity build-up.

  3. Low abrasiveness, minimizing wear on application equipment and substrate surfaces.

  4. Consistent particle size distribution ensures uniform haze control and reproducible finish quality.

  5. Chemically inert silica surface enables broad compatibility with resins including acrylics, polyurethanes, and alkyds.

Typical Applications Of HOMSIL A370 Silica-based Matting Agent

  1. Architectural and industrial maintenance coatings requiring low-sheen, durable finishes.

  2. Wood coatings for furniture, flooring, and cabinetry where clarity and tactile smoothness are critical.

  3. Automotive refinish clearcoats seeking controlled gloss reduction without compromising DOI (Distinctness of Image).

  4. Plastic coatings for consumer electronics and appliances demanding scratch resistance and matte aesthetics.

  5. UV-curable inks and coatings for packaging and decorative printing applications.
