Good Dispersion Silica Dioxide Paint Matting Agent Use For Gravure Printing Inks
Introduction
Silicas for matting there are two here are two groups which differ in terms of their production process. One is the hydro-thermal process, which produces silicas with a relatively soft morphology, the other is by using the silica-gel process products can be obtained which have a harder morphology. Both processes can produce standard silica and after treated products. After treatment means that the silica surface can be partially modified with organic (waxes) or inorganic materials.
Characters
Good incorporation and dispersion properties, outstanding rigidity. Advanced rubbing technology makes narrower distribution of diameter of granules, so that matting agent can be easily added in any production procedure and can be easily dispersed, which saves the processing time.
