With the increasing global awareness of environmental protection, the leveling agent industry is undergoing a green revolution. Leveling agents are developing towards a more environmentally friendly, efficient, and multifunctional direction. The development and application of new environmentally friendly leveling agents have become a hot topic in the industry, and traditional solvent based leveling agents are gradually being replaced by water-based, solvent-free, or low VOC (volatile organic compound) environmentally friendly leveling agents. These new leveling agents not only meet strict environmental regulations, but also demonstrate significant advantages in improving coating leveling efficiency, enhancing coating adhesion, and reducing energy consumption.

For example, the development of bio based leveling agents that utilize renewable resources such as vegetable oils or microbial fermentation products not only reduces dependence on fossil fuels, but also endows coatings with superior biodegradability. In addition, the application of nanotechnology has also opened up new paths for the innovation of leveling agents. Through the surface modification of nanoparticles, precise control of the microstructure of coatings has been achieved, further improving the overall performance of coatings.

While pursuing green and sustainable development, the performance requirements for leveling agents in the coating industry are constantly increasing. Future leveling agents not only need to have excellent leveling performance, but also need to have good weather resistance, water resistance, chemical resistance, and so on. Therefore, the innovation of high-performance and green leveling agents will become an important direction for future development. Through the latest research achievements in nanotechnology, polymer materials science, and other fields, new leveling agents with special functions can be developed, such as self-healing leveling agents, antibacterial leveling agents, etc., to meet the urgent demand of the coating industry for high-performance coatings.
