With the increasingly strict environmental regulations and the continuous development of the coating industry, the modification technology of leveling agents has become a research hotspot. By introducing nanomaterials, functional monomers, and other means, leveling agents can be endowed with superior performance and a wider range of applications. For example, nano leveling agents have better dispersibility and leveling effect, which can significantly improve the glossiness and hardness of coatings.

The development and use of environmentally friendly leveling agents is an important trend in the industry's development. These leveling agents usually have the characteristics of low VOC (volatile organic compound) emissions, biodegradability, etc., and have a relatively small impact on the environment and human health. At the same time, strict adherence to safety operating procedures is required during production and use to ensure personnel safety.

The compatibility of leveling agents with other additives directly affects the overall performance of the coating. Therefore, in the formulation design process, sufficient compatibility testing is required to ensure that the leveling agent can work synergistically with other additives to jointly improve the construction performance and coating quality of the coating.

The methods for evaluating the performance of leveling agents mainly include laboratory testing and practical application verification. Laboratory testing can evaluate the leveling effect of leveling agents by measuring indicators such as surface tension, viscosity, and flowability of coatings; However, practical application verification requires observing the overall performance of the coating, such as appearance quality, glossiness, and weather resistance, under specific construction conditions.
