Precipitated Silica Matting Agent As White Powder Used For Wood Coatings
Description
Matting Agent specialized used for Wood Coatings. It is a micronized precipitated silica matting agent for both solvent-based and water-based system. The appearance as white powder. Silica Matting Agent reduce the gloss of a variety of products including coatings, paints, inks, lacquers, varnishes, while providing lower viscosity and better flow capability.
Characters
1, Super matting efficiency. High pore volume reach to 1.8-2.0 ml/g, and fine control of the particle size and particle size distribution.
2, Excellent transparency: High purity of silica product ensures that refractive index can inosculate with resin index.
3, Surface smoothness and improvement in scratch resistance: These silicas have minimal effect on the physical properties, allowing development of smooth films with excellent hand-feel, scratch resistance and stain resistance.
Applications
1, Wood Furniture coatings, NC wood coatings, PU Wood coatings, UV wood coatings.
2, Printing Inks, Gravure Printing Ink, Offset Printing Ink, Screen Printing Ink, Printing Packing Material.
3, Industrial Coating, Metal baking Coating, Decorative Coating
4, Automotive Coating, Car Coating.
5, Plastic Coating, 3C Coating.
