Silicone Leveling agent is a type of surface active agent. It can help reduce the surface tension of the paint, make the coating much easier to level, and get a smooth 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 industry. And it is not a mutifuctional agent, the application should match in the coating system, and necessary testing should be done beofore it is used.
