Features Of WR Grace SYLOID 35 Matte Powder

  1. Highly porous amorphous silica with controlled particle size distribution for consistent matting performance.

  2. Low oil absorption enables efficient formulation in solvent-based and high-solids coatings without excessive viscosity build.

  3. Excellent transparency retention in clear coats and varnishes, minimizing haze while delivering uniform matte finish.

  4. Chemically inert and thermally stable up to 800 °C, supporting compatibility across diverse resin systems and curing conditions.

  5. Free-flowing, dust-reduced powder form enhances workplace safety and simplifies handling during industrial blending.

Typical Applications Of WR Grace SYLOID 35 Matte Powder

  1. Architectural and industrial solvent-borne topcoats requiring durable, low-sheen finishes.

  2. Automotive refinish clearcoats where clarity, scratch resistance, and controlled gloss reduction are critical.

  3. Wood coatings including nitrocellulose (NC) and acrylic lacquers for furniture and cabinetry.

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

  5. Plastic coatings and overprint varnishes for rigid substrates such as PVC and polycarbonate.
