A new acrylic epoxy hybrid (AEH) water based dispersion has been developed for two-components coating applications for several years. This new AEH dispersion can be used to replace the conventional water based epoxy dispersions for concrete and metal coatings. The curing agent selection for the new AEH dispersion is critical for metal applications for both formulation stability and the performance such as corrosion resistance, water resistance and UV durability. This paper discusses the utility of using ζ-potential and water solubility in curing agent selection.
