Leveling Agent

Leveling agents are primarily used to improve the flow and leveling properties of coatings, ensuring that the coating can spread evenly on the substrate surface to form a smooth and even coating. The application of leveling agents effectively eliminates surface defects that may occur during application, such as brush marks, orange peel, and bubbles, thereby improving the quality and appearance of the coating.

During coating application, the leveling performance of the coating may be affected by uneven surface tension, leading to uneven distribution or an uneven film. Leveling agents reduce the surface tension of the coating, improving its wettability to the substrate and promoting uniform spread of the coating on the substrate surface, thus achieving a smooth and glossy coating. Through this action, leveling agents help the coating fill in the microscopic unevenness of the substrate surface, ensuring a smooth and even coating and avoiding defects such as bubbles and scratches.

The mechanism of action of leveling agents is based on adjusting the rheological properties of the coating and optimizing its flow and spreading ability during application. During application, leveling agents enable the coating to have better flowability, promoting uniform spread and filling the fine textures of the substrate surface, thereby effectively ensuring the overall smoothness, gloss, and visual effect of the coating. It improves the appearance of the coating while enhancing its durability and decorative effect.

It is widely used in coating systems requiring high decorative properties and surface finishes, such as high-gloss coatings, furniture coatings, and automotive coatings. It plays a crucial role in these coating systems that demand perfect coating results.
