Features Of WR Grace SYLOID C803 Matte Powder

  1. Highly engineered amorphous silica providing exceptional matte finish and surface softness.

  2. Low oil absorption for efficient formulation integration and reduced viscosity impact in coatings and inks.

  3. Consistent particle size distribution ensures uniform dispersion and reliable optical performance.

  4. Chemically inert and thermally stable, supporting compatibility across solvent-based, water-based, and UV-curable systems.

  5. Low abrasivity minimizes equipment wear during high-shear processing and milling.

Typical Applications Of WR Grace SYLOID C803 Matte Powder

  1. Architectural and industrial coatings requiring durable, non-glare finishes.

  2. Printing inks—especially gravure and flexographic—for controlled gloss reduction on packaging films and labels.

  3. UV-curable wood and plastic coatings where clarity and matte effect must be preserved post-cure.

  4. Automotive refinish topcoats seeking OEM-matched haze control and scratch resistance.

  5. Specialty adhesives and sealants needing tactile softness and anti-blocking functionality.
