Silicone leveling agent are used very common in coating and ink. It can help reducing the surface tension of the coating film. It can also eliminate the difference of surface tension and make a good surface state for the coating film. It can prevents Bernard swirl, orange peel and shrinkage holes of coating film. By decreasing the surface tension, the spreadibility of coating can be improved as well as the adhesion. Silicone leveling agent are used very early and very often in the coating and ink industry.
