With the increasing global environmental awareness and strict regulations, the innovation and development of green leveling agents have become an important issue in the coating industry. The application of nanotechnology in green leveling agents can significantly improve their performance. Through surface modification and dispersion techniques of nanoparticles, nano leveling agents with excellent leveling performance and environmental characteristics can be prepared. Biotransformation technology is a method of converting natural raw materials into leveling agents using biocatalysts such as microorganisms or enzymes. This method has the characteristics of low energy consumption, low pollution, and high efficiency, and is an important innovative direction for green leveling agents.

With the continuous improvement of coating performance requirements in the coating industry, green leveling agents have also shown a trend towards high-performance development. By improving the molecular structure and functional characteristics of leveling agents, green leveling agents with excellent wear resistance, weather resistance, and oxidation resistance can be prepared.

Multifunctionality is another important development trend of green leveling agents. By combining the leveling function with other functions such as defoaming and thickening, a multifunctional integrated green leveling agent can be prepared, simplifying the coating formula and improving production efficiency.

At present, the technical bottlenecks of green leveling agents mainly lie in limited raw material sources, complex preparation processes, and insufficient performance stability. These challenges require joint efforts within and outside the industry to strengthen technological research and innovation, and promote the continuous progress of green leveling agent technology. Due to the relatively high cost and limited market awareness of green leveling agents, their market acceptance still faces certain challenges. Therefore, strengthening market promotion and publicity, and increasing consumers' awareness and acceptance of green coatings are important directions for the development of green leveling agents.

The innovation and development of green leveling agents are important components of the green transformation of the coating industry. By applying innovative technologies and driving development trends, we can overcome the challenges we face and promote the continuous progress and widespread application of green leveling agent technology. This not only helps to improve the environmental protection level of the coating industry, but also makes a positive contribution to the global environmental protection cause.
