In most cases, leveling agents and wetting agents are often discussed together. However, in fact, leveling agents and wetting agents are two different products. In some practical applications, leveling agents may have better performance. The wetting effect is often mistaken for wetting agents. This is one of the main reasons why leveling agents and wetting agents are discussed together.
In the wetting properties of wetting agent products, the size of surface tension is an important indicator related to the wetting ability of the product, followed by its compatibility. According to the basic principle of paint film leveling, the final driving force for leveling comes from surface tension. An additive, the stronger its ability to reduce surface tension, the stronger its wetting ability.
