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

UV

Defoamer is an additive for eliminating foam. A large amount of foam will be produced in the production and application process of coatings, textiles, medicine, fermentation, paper making, water treatment, petrochemical and other fields, which will affect the product quality and production process. Based on the inhibition and elimination of foam, a specific amount of defoamer is usually added to it during production

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.
