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.
Silica matting agents are additives used in wood coatings to create a matte or semi-matte finish on the surface of the wood.
These agents work by scattering light that hits the surface of the coating, reducing its glossiness and giving it a more subdued,
matte appearance.
Silica, or silicon dioxide, is a natural material that is often used in matting agents because of its excellent light-scattering properties.
It is typically used in the form of a very fine powder, which can be easily mixed into the coating material.
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
redispersion.
