White and Colloidal Powder Silica Matting Agent Pore Volum 1.8-2.0 ml/g Use For Wood Coatings
Description
Matting Agent specialized used for the matte wood coating. A broad array of non-treated and wax-treated products, covering high-purity silica content, high pore volume and by fine control of the particle size and particle size distribution. Careful design and control of silica physical properties ensure dispersion stability, hand-feel, anti-setting behavior and scratch resistance in solvent-borne and water-borne system.
Characters
Highest matting efficiency: High pore volume reach to 1.8-2.0 ml/g, and fine control of the particle size and particle size distribution.
Excellent transparency: High purity of silica product ensures that refractive index can inosculate with resin index.
Outstanding anti-settling properties: The products which with wax surface treatment help prevent settling and improve re-dispersion.
