替换城市 Principle and influencing factors of special Free of silicone defoamers agents for paints(1)

matte

epoxy

Organosilicon type
silicone oil
The commonly used silicone oils include polydimethylsiloxane and polymethylphenylsiloxane. Polydimethylsiloxane is used in paints and inks. Although polymethylphenylsiloxane has good compatibility, it does not have the ability to control surface state, so it is basically not used in leveling agents, and is mostly used for high-temperature resistance

Surfactant

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

leveling

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.
