Wetting agents are a type of chemical substance that can significantly reduce the surface tension of liquids, promote the spreading and permeation of liquids on solid surfaces. They are widely used in various fields such as coatings, textiles, printing, cleaning, agriculture, etc. According to their chemical structure and functional characteristics, wetting agents can be divided into four categories: non-ionic, anionic, cationic, and zwitterionic. Each type of wetting agent exhibits unique advantages in different application scenarios.

Wetting agents adsorb onto solid surfaces, forming a thin film that effectively reduces the tension at the solid-liquid interface, making it easier for liquids to penetrate into the tiny pores or cracks on the solid surface. This process is called wetting, which depends on the molecular structure and charge characteristics of the wetting agent, as well as the properties of the solid surface.

Wetting agents have a wide range of applications in the coatings industry, improving the leveling of coatings, reducing bubble generation, and ensuring uniform and smooth coatings. Textile printing and dyeing improves the wettability of fibers, making it easier for dyes to penetrate uniformly, and enhancing dyeing efficiency and quality. In the field of cleaning, enhance the penetration of cleaning agents into stains and improve cleaning effectiveness. Agriculture, as a pesticide additive, promotes the uniform distribution of medicinal solutions on plant surfaces and enhances their efficacy.

With the increasing awareness of environmental protection, environmentally friendly wetting agents have become a research and development hotspot. These products have low toxicity, biodegradability, and reduce environmental pollution. At the same time, strict adherence to safety operating procedures is required during use to ensure personnel safety.
