Excellent Dispersion Silica Matting Agent CAS No.:7631-86-9 Used For Printing Inks
Description
Silica Matting Agent popular used For Matt Printing Inks. It is synthetic amorphous micronized precipitated silica appearing as white powder and for both solvent-based and water-based system. It provides a superior matting and flatting, excellent coating appearance and transparency, cost efficient, effective anti-settling agent and easy dispersion, smooth, abrasion resistant films of high surface quality. 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.
Feature
1, 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.
2, High Matting Efficiency. High pore volume reach to 1.8-2.0 ml/g, and fine control of the particle size and particle size distribution.
3, Excellent transparency: High purity of silica product ensures that refractive index can inosculate with resin index.
