Leveling agents can improve paint defects

There are many defects and deficiencies in the performance of coatings, and some additives must be used. Leveling agent is an indispensable one among these additives. The role of leveling agents should not be underestimated.

1. Anti shrinkage hole

Shrinkage on the surface of the coating is a common problem. The cause of shrinkage is due to the imbalance of surface tension. Adding leveling agents can effectively improve this problem.

2. Prevent orange peel, prevent color from blooming, prevent extinction, light leakage, and blooming

Exercise is the main root cause of the above problems. As long as the surface tension of the coating is reduced, the underlying coating cannot be pushed to the surface, and the above problems will not occur. So adding organic silicon leveling agents that can control the surface state and reduce surface tension is the best method. If organic silicon additives cannot solve the problem, then consider choosing organic fluorine additives.

3. Prevent ripples

The generation of ripples is also caused by uneven surface tension. This can be solved by using organosilicon leveling agents that reduce surface tension. But when the vertical spraying produces upper and lower ripples, it is best not to use leveling agents that reduce surface tension to solve it, otherwise it will become more and more serious. The best way is to add leveling agents that do not reduce surface tension.

Different types of leveling agents have different mechanisms of action and effects, and even if the type of leveling agent is the same and the structure is different, the use effect will also be different. So when applying leveling agents, the selection should be based on the problems that the coating needs to overcome and the structural category of the additives.
