A deeper understanding of the mechanism of action of defoamers in coatings can help us better select and apply such additives. Meanwhile, exploring its technological advantages is also an important part of promoting technological progress in the coatings industry.

Action mechanism: when the surface tension is reduced, the defoamer molecules can quickly diffuse to the surface of foam, reducing its surface tension and making foam easy to break. When the foam structure is damaged, some defoamers can penetrate into the foam wall to destroy its stability and accelerate the bursting of foam. Thickening and inhibition. Some defoamers can also inhibit the formation and aggregation of foam by increasing the viscosity of the paint system.

Technical advantages: high efficiency, which can quickly and thoroughly eliminate foam in the paint and improve the construction efficiency. Compatibility, compatible with multiple coating systems, does not affect the basic performance of the coating. Durability refers to the ability to maintain a stable defoaming effect during the storage and use of coatings. Environmental friendliness, with the increasingly strict environmental regulations, low VOC, non-toxic and harmless defoamers have become the mainstream in the market.
