Matting Agent as an additive used for Matte Coatings
Description
1, 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. It divide into non-treated and Wax-treated organic products, shows good performance of high matting efficiency, better transparency, excellent hand feeling in solvent and water based system. Our matting agent has good control of particle size and favorable stability.
2, Matting Agent specialized used for the matte wood coating. It provided high matting efficiency, excellent coating appearance and high transparency. As well as low oil absorption, easy dispersion and smoothly touch with minimal impact of viscosity.
Characters
1, 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.
2, Outstanding anti-settling properties: The products which with wax surface treatment help prevent settling and improve re-dispersion.
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.
4, Excellent transparency: High purity of silica product ensures that refractive index can inosculate with resin index.
