How the leveling agent works

Leveling agent is a kind of additives widely used in coating, ink and other fields, its main function is to improve the surface smoothness of the coating, reduce the coating film defects, such as orange peel, pinholes, shrinkage holes and so on. Its working principle can be elaborated from the following aspects:

1. Reduce surface tension: By reducing the surface tension of the coating, the leveling agent makes it easier to spread the coating on the substrate, thereby reducing the uneven surface tension. This helps to eliminate the uneven surface of the coating, resulting in a smooth coating.

2. Promote fluidity: the leveling agent can improve the fluidity of the coating, so that it is evenly distributed during the curing process. This is achieved by adjusting the viscosity of the paint, so that the paint can flow better during the drying process and fill the surface defects.

3. Reduce surface defects: the leveling agent can effectively reduce the defects of the coating surface, such as bubbles, shrinkage holes, etc. By adjusting the surface tension and viscosity of the coating, it makes it easier for bubbles to escape and prevents the coating from shrinking during the drying process.

4. Improve the gloss of the coating: leveling agent can significantly improve the gloss of the coating by improving the flatness of the coating. The smooth surface is better able to reflect light, giving the coating a higher gloss and aesthetics.

In summary, the leveling agent significantly improves the surface quality of the coating by reducing surface tension, promoting fluidity, reducing surface defects and improving gloss, making it more flat, smooth and beautiful.
