Wetting agents are one of the key additives in coating formulations, which can effectively improve the leveling of coatings, reduce pinholes and orange peel phenomena, and enhance coating quality. It is crucial to choose the appropriate wetting agent based on the type of coating (such as water-based coatings, solvent based coatings) and the required performance.

Wetting agents optimize the spreading and penetration of coatings on substrates, reduce the formation of bubbles and shrinkage cavities, and significantly improve the smoothness and glossiness of coatings. In addition, it can enhance the adhesion of the coating and extend its service life.

With the increasingly strict environmental regulations, water-based coatings have become mainstream due to their low VOC emissions. Correspondingly, the development of environmentally friendly wetting agents suitable for water-based coatings has become an industry trend. These wetting agents not only need to meet performance requirements, but also need to have good biodegradability and low toxicity.

Technical challenges include balancing wetting performance and coating stability, and reducing costs without sacrificing performance. The solution includes developing new and efficient wetting agents, optimizing coating formulations, and strengthening production process control.

A certain coating company has successfully solved the problem of air bubbles in water-based coatings during construction by introducing a new environmentally friendly wetting agent, while improving the weather resistance and glossiness of the coating, winning market praise.
