Leveling agents are generally divided into two categories. One type of leveling agent works by adjusting the viscosity and leveling time of the paint film. Most of these leveling agents are organic solvents or mixtures with high boiling points, such as isophorone, diacetone alcohol, Solvesso 150, etc; The other is to adjust the surface properties of the paint film to play a role, and generally speaking, leveling agents refer to this type of leveling agent. This type of leveling agent migrates to the surface of the paint film through limited compatibility, affecting surface properties such as interfacial tension of the paint film, and achieving good leveling of the paint film. Depending on the chemical structure, there are three main types of leveling agents: acrylic acids, organosilicon, and fluorocarbon compounds

替换城市  Principle of special UV curing defoamer for paints:

Good paint defoamers not only have a good defoaming effect in paint systems, but also maintain defoaming ability at room temperature and under heating environments. In addition, it cannot be compatible with foam system. If the compatibility is good, it will help to produce foam. While the paint UV curing defoamer has good dispersibility in the foaming system, specifically refers to the uniform and smooth diffusion of the defoamer on the surface, which can cover the foam to achieve the elimination effect. Its working principle is to reduce the surface tension of the liquid around the foam, so that small foam can gather into large foam, and finally foam will burst.
