Q: The more leveling agent added, the better the leveling effect on the coating?

Question:Leveling agentIs it better to add more to level the coating?

Answer:The leveling performance of coatings has always been a crucial aspect of coating production. Almost every type of coating requires the addition of a leveling agent, as it can endow the coating with excellent leveling properties and prevent issues such as orange peel and shrinkage. So, does the more leveling agent added, the better? This is not necessarily the case. While each leveling agent brings excellent leveling to the coating, it also brings some corresponding side effects.

Leveling agent is a kind of surfactant. Although it can improve its leveling performance when added to the coating, it will also cause a large number of foam in the coating, which is a problem we need to pay attention to. So what problems will occur if too much leveling agent is added?

1. The adhesion of the coating deteriorates

2. The leveling performance of the coating may also have a reverse effect

3. Surface defects such as shrinkage and porosity in coatings

4. A large amount of leveling agent will cause excessive foam in the coating, thus increasing the burden of defoaming

Therefore, from the above, it can be seen that the more leveling agents added, the better. On the contrary, it can bring a series of adverse reactions to the coating. The amount of leveling agent added generally depends on one's own coating formula and requires continuous testing to determine the most suitable amount.
