Generally, the structure of the leveling agent in coatings generally consists of two parts, the segments compatible with the system and the segments that are incompatible with the system and have a lower surface tension than the system. During the film formation during construction, due to the separation and migration of incompatible segments with low surface tension, the additives will spontaneously migrate to the surface of the coating system to form a monomolecular film, thereby providing the system with uniform surface tension and eliminating surface tension. Various surface defects of paint film caused by gradient.
