In the production process of coating inks, mixing and stirring of raw materials is an indispensable link. Many coating ink formulas contain surfactants, the purpose of which is to improve the dispersibility, wettability and other properties of coating inks. However, the presence of surfactants will reduce the surface tension of the system, making it easy for air to mix into it to form foam. Therefore, the emergence of defoamers for coating inks can effectively solve the foam.
Application scenarios of defoamers for coating inks
Foams will make the surface of coating inks uneven. When the coating is used for coating, the foam will form pores or pits on the surface of the coating, seriously affecting the beauty of the coating. For inks, it will cause defects on the surface of printed products and affect the printing quality.
The primary function of defoamers for coating inks is to eliminate the foam that has been generated. It can quickly break the foam and restore the normal state of the coating ink system. Secondly, defoamers also have the ability to control the generation of new foam, thereby maintaining the stability of coating inks during production, storage and use.
In terms of coating production, whether it is oil-based coatings, water-based coatings or powder coatings, defoamers play an important role. In the production of inks, such as offset inks, gravure inks, screen printing inks and other types of inks, defoamers are also required to ensure the quality of the inks and printing effects.
Defoamers for coating inks play an indispensable role in the coating ink industry. It helps to improve the quality of coating inks, improve the performance during production and use, and continue to innovate and progress with the development of the industry.
