Wetting agents are a type of chemical substance that can significantly reduce the surface tension of liquids, promote rapid spreading and penetration of liquids on solid surfaces. They are widely used in various fields such as industry, agriculture, and daily chemical products, and are indispensable and important additives in these industries. Wetting agents, through their unique molecular structure, can form a thin film between liquid and solid interfaces, reducing the contact angle between the two and achieving rapid and uniform wetting effects.

There are various types of wetting agents, which can be classified into anionic, cationic, nonionic, and zwitterionic types based on their chemical structures and mechanisms of action. Different types of wetting agents have different wetting properties and application characteristics, suitable for different systems and environmental conditions.

The main functions of wetting agents include: improving the leveling and coverage of coatings, reducing coating defects; Promote the adhesion and penetration of pesticides on plant surfaces, and enhance their efficacy; Improve the cleaning effect of detergents and enhance their ability to remove dirt; And play a key role in multiple industries such as textiles and papermaking.

With the advancement of technology and the increasing awareness of environmental protection, the research and application of wetting agents are also constantly developing. Environmentally friendly wetting agents have attracted much attention due to their low toxicity, low residue, and biodegradability, and have become an important direction for the future development of wetting agents.
