| Abstract: | A kind of Ultraviolet(UV)-curable waterborne polyurethane-acrylate coatings was synthesized from toluenediisocyanate(TDI), polyetherdiol(PPG), dimethylolpropionicacid(DMPA), 1,4-butanediol(BDO), triethanolamine(TEOA) and 2-hydroxyethyl acrylate(HEA). The effects of carboxyl content, degree of neu-tralization, molecular weight of polyetherdiol and NCO/OH molar ration on the particle size, viscosity, stability of emulsions and on the water resistance and toluene resistance of the coating film were investigated. |
