The selection and usage techniques of leveling agents in coating formulations directly affect the performance of the coating and the quality of the final coating film. Different types of coatings require the selection of different types of leveling agents. For example, solvent based coatings often use high boiling point solvent mixtures, while water-based coatings are more suitable for using acrylic or silicone leveling agents. Select the appropriate leveling agent based on the performance requirements of the coating, such as glossiness, hardness, weather resistance, etc. For example, for coatings that require high glossiness, leveling agents with brightening effects can be chosen.

When choosing leveling agents, their impact on the environment should be considered, and environmentally friendly leveling agents with low VOC and biodegradability should be selected.

The amount of leveling agent added should be determined according to the formula and performance requirements of the coating, generally ranging from 0.1% to 1% of the total coating amount. Leveling agents can be added at various stages of coating production, but it is best to add them after the coating is evenly mixed to ensure their full dispersion and effectiveness. After adding leveling agent, the coating should be thoroughly stirred to mix evenly and avoid situations where the local concentration is too high or too low.

When using leveling agents, it is important to avoid excessive addition as it may lead to a decrease in coating performance, such as reduced glossiness and shrinkage. There may be differences in compatibility between different leveling agents, and compatibility testing should be conducted before use to ensure that they do not have adverse reactions with other components in the coating.

In addition, leveling agents should be stored in a cool, dry, well ventilated place, away from direct sunlight and high temperatures. In summary, the selection and application techniques of leveling agents are crucial for the performance of coatings and the quality of the final coating. By selecting and using leveling agents reasonably, the leveling, glossiness, and weather resistance of coatings can be significantly improved, making important contributions to the development of the coating industry.
