Application of defoamer in environment-friendly water-based ink

In recent years, with the needs of building an environment-friendly society and the improvement of people's living standards, the amount of various packaging materials has increased significantly and become more and more exquisite, and the demand for water-based coatings has increased significantly, especially the application of water-based inks has increased year by year

The rapid development of water-based coatings and inks has led to the development of water-based coating additives and ink additives.

The main defoamers used in water-based inks are:

(1) Traditional defoamer: mineral oil wax, metal soap,

(2) Polyether block type defoamer: This type of defoamer has excellent compatibility, less paint film surface defects, does not affect gloss and haze, and is suitable for inks with high surface requirements

(3) Silicone defoamer: mainly include emulsion type polysiloxane and polyether modified silicone defoamer

(4) Compound defoamer: mineral oil/wax/organosilicon, mineral oil/hydrophobic particle/organosilicon, organosilicon/hydrophobic particle,
