Coniglio, N.Nguyen, K.Kurji, R.Gamboa, E.2013-07-162013-07-162013Progress in Organic Coatings, 2013; 76(9):1168-11770300-9440http://hdl.handle.net/2440/78807In the present work, water sorption kinetics and equilibrium in 100% solids epoxy coatings are investigated by immersion into distilled water baths from 20 to 85 C (absorption tests) and drying in a furnace between 60 and 85 C (desorption tests). The gravimetric liquid sorption measurements reveal a non-Fickian two-stage diffusion behaviour during both absorption and desorption. The effect of hydrothermal history was also investigated. Cycling the immersion bath temperature increases the saturation values. Alternating sorption-desorption cycles increases the speed of water movement. The hydrothermal-induced coating degradation and the sorption modes are discussed. © 2013 Elsevier B.V. All rights reserved.en© 2013 Elsevier B.V.
