In the production and application of coatings and inks, leveling agents play an indispensable role. Its core function lies in improving the surface tension of coatings and inks, enabling them to spread evenly on the substrate surface and form a smooth and flat film layer.
When coatings or inks are applied to the substrate, if the surface tension is uneven, defects such as craters and orange peel will occur. Leveling agents can reduce the surface tension of the system, allowing the liquid to level automatically under the action of surface tension and eliminating these defects. In addition, the leveling agent can also inhibit the formation of foam, prevent problems such as pinholes in the film layer caused by residual bubbles, and ensure the integrity of the film formation.
During the ink printing process, leveling agents help the ink transfer better onto the substrate, making the printed graphics and text clear, the colors uniform, and enhancing the quality and aesthetic appeal of the printed matter. In the field of coatings, especially in products with extremely high surface quality requirements such as automotive paint and wood paint, leveling agents can significantly enhance the gloss and vividness of the coating, endowing it with a good visual effect and texture. It can be said that the rational use of leveling agents has greatly optimized the performance and application effects of coatings and inks.
