摘要：

The objective of this paper was to formulate high performance water-based paints by an esterified epoxy resin, synthesized by reacting epoxy resin with pyromellitic dianhydride (PMDA) and pigmented with non-toxic phosphate using varying pigment-volume concentrations (PVCs). The influence of pigment concentrations on some physico-chemical properties was evaluated and assessed for the optimized PVC coating formulation. The structural and thermal stability of the epoxy ester vehicle was also evaluated through FT-IR and thermogravimetric analysis (TGA). Film properties of the coatings were studied and it was found that the coating composition at lower PVCs exhibited better film property over higher PVCS. (C) 2009 Elsevier B.V. All rights reserved.
