Inorganic pigment, which are make by mixing various chemicals together, are used for colored inks, such like silica matting agent combine with other chemical materials to make the matte finish inks.
Characters
Matting agents with smaller average particle size do not give a quality matting effect, but they produce smooth paint films
In contrast, products with larger particle sizes are stronger in matting efficiency but the paint film surface is not so smooth. Matting agents with large particles show a tendency to build up separation and sedimentation in clear paint systems during storing time
