Wetting Agents & Dispersants
Good wetting and coating properties of a paint are dependent upon its surface tension. A wetting agent functions to adjust and improve the surface tension of paint formulations, providing paint excellent leveling property, improving coating area, thus enhancing the color exhibit of pigmented paints. At the same time, a good wetting agent should minimize foaming and cratering.

Dispersants play an important role in paint applications. A good dispersant offers excellent properties of a paint formulation, such as color exhibit, water resistance, and storage stability, among others.
