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

and

recoating

dispersant

The main component of mineral oil UV curing defoamer United States is mineral oil, or any other oil that is insoluble in the foaming medium, as the carrier, accounting for approximately 50% to 70%. Its specific gravity is the key. Too much will affect its solubility and emulsification, while too little will affect its stability and effectiveness.

Inorganic hydrophobic particles account for about 10% of the total, and they are evenly dispersed in mineral oil, which is one of the key factors because their hydrophobic strength determines the effectiveness of defoaming performance, which can help UV curing defoamer United States factors reach the surface of the liquid film more easily, allowing the defoaming agent to quickly blend with the liquid film to increase defoaming speed.
