Studies of waterborne emulsion of chemically modified epoxy resin

摘要

The bisphenol-A type epoxy resin was modified by p-aminobenzoic acid. The modified resins were characterized using IR spectroscopy and differential scanning calorimetry (DSC). The progress of emulsification process was characterized by measuring the variations of conductivity and viscosity while dropping water into the modified resin solution. The factors influencing the emulsion particle size of the waterborne coating films of the modified resins were investigated.
