In the industrial production of coatings and inks, foam formation is generally an undesirable factor that must be eliminated.Beyond selecting appropriate raw materials and optimizing process conditions to minimize foam generation, the primary solution is adding various defoamers. These additives function by reducing surface tension and destabilizing foam films, thereby effectively suppressing or eliminating bubbles.
