Leveling agent is a coating agent that can make the coating form a flat film


Leveling agent is a commonly used coating agent, which can promote the formation of a flat, smooth and uniform coating film during the drying process. A class of substances that can effectively reduce the surface tension of the finishing liquid and improve its leveling and uniformity. It can improve the permeability of the finishing fluid, reduce the possibility of spots and spots during brushing, increase the coverage, and make the film uniform and natural. They are mainly surfactants, organic solvents, etc. There are many kinds of leveling agents, and the types of leveling agents used for different coatings are also different. High boiling point solvent or butyl cellulose can be used in solvent-based finishing agent. Surfactants or polyacrylic acid and carboxymethyl cellulose are used in water-based finishing agents.
