...Zhe Li; Hongpeng Zheng; Li Liu; Fandi Meng; Yu Cui; Fuhui Wang Purpose The purpose of this paper is to investigate the effect of urea–formaldehyde (UF) nanoparticles on the barrier property and delamination resistance for epoxy coating in a 3.5% NaCl aqueous solution. Design/methodology...

... spectroscopy and x-ray diffraction techniques were used to study the surface morphology, microstructural features, elemental composition and structure of the samples. Findings The failure occurred in the form of delamination and blistering of coated layer. Presence of solar radiation, humidity and water...
