Paint, Inks & Coating
Paint, ink and coating formulations generally contain pigments, fillers, additives and solvents, all of which are incorporated into a binder. The solvents can be organic or water-based. Producing a consistent and homogeneous product from such a varied combination of raw materials is a challenge for the milling process. Development of both gloss and color strength are critical factors, and are often highly dependent on media selection.
In order to demonstrate the effect of the proper media selection, Saint-Gobain Zirpro has produced a video where different sizes of ZirPro premier product Zirmil® Y are tested and the effects on grind of pigment dispersion monitored. The results conclusively identify the potential for increased productivity and/or improved grind quality, if bead size selection is correct.
