Surface tension is a manifestation of the cohesive force between liquid molecules, which forms an "elastic film" on the surface of the liquid to resist external deformation problems. In daily life and industrial production processes, we often encounter the problem of difficulty in evenly spreading or penetrating liquids, and behind these phenomena, a key factor cannot be separated - surface tension. Wetting agents are widely used in multiple industries due to their ability to precisely regulate surface tension.   

Wetting agent molecules can quickly migrate to the liquid interface, reduce initial surface tension, and maintain long-term wetting effect by forming a monolayer. Wetting agents can also effectively adjust the molecular structure or compounding scheme for different materials, achieving "customized" wetting.

Nowadays, wetting agents have been widely used in our daily lives. In the future, intelligent responsive wetting agents will be a new direction of scientific research. With the development of nanotechnology and green chemistry, wetting agents are also moving towards the direction of "high efficiency, environmental protection, and intelligence".
