Leveling agents are a class of substances that can effectively reduce the surface tension of the coating liquid and improve its leveling and uniformity. It can improve the permeability of the coating liquid, reduce the possibility of spots and scars during brushing, increase coverage, and make the film formation uniform and natural. Mainly surfactants, organic solvents, etc. There are many types of leveling agents, and different types of leveling agents are used in different coatings. High-boiling solvents or butyl cellulose can be used in the solvent-based finishing agent. In water-based coating agents, surfactants or polyacrylic acid, carboxymethyl cellulose, etc. are used.

One is by adjusting the viscosity of the paint film and the leveling time. Most of these leveling agents are high-boiling organic solvents or their mixtures, such as isophorone, diacetone alcohol, Solvesso150, etc .;

Tomorrow we will push you for a certain formula system, how to choose the right leveling agent variety according to the nature of the formula and the performance expected from the leveling agent, please continue to pay attention to us!
