Wetting agents are added to the waterborne coatings in order to increase the wetting of the substrate, and to improve the compatibility with pigments and other components. Selection of the suitable wetting agent for desired formulation and application properties is critical.
For example, anionic wetting agents can have
coatings where micro-foam cannot be
