In the field of coatings, leveling agent is a key auxiliary agent to improve the quality of coatings. Its core role is to improve the leveling of coatings and make the coating surface smoother. After the coating is applied, the leveling agent can reduce the surface tension between the coating and the substrate, so that the coating can be evenly spread on the surface of the substrate to avoid defects such as brush marks and roller marks.
At the same time, the leveling agent can also effectively prevent shrinkage holes in the coating. Shrinkage holes are depressions formed by local shrinkage of the coating due to uneven surface tension of the coating. The leveling agent adjusts the surface tension to make the surface tension evenly distributed, thereby reducing the occurrence of shrinkage holes. In addition, the leveling agent helps to eliminate bubbles in the coating, allowing bubbles to be discharged quickly, and avoiding the appearance and performance of the coating affected by residual bubbles. In terms of improving the gloss of the coating, the leveling agent also plays an important role. It can make the coating surface smooth like a mirror, reflect light more evenly, and make the coating present a good decorative effect. It is widely used in the coating of furniture, automobiles, construction and other industries.
