替换城市  Principle of special Free of silicone defoamers for paints:

Leveling agent is a commonly used coating additive that can promote the formation of a flat, smooth, and uniform coating film during the drying process. A class of substances that can effectively reduce the surface tension of finishing fluids and improve their leveling and uniformity. It can improve the permeability of the finishing liquid, reduce the possibility of spots and stains during brushing, increase coverage, and make the film formation uniform and natural. Mainly surface active agents, organic solvents, etc.

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 Free of silicone defoamers 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.
