Sorption and desorption data are reported for water in epoxy at 25°C and 70°C. A Monte Carlo model based on the dual‐sorption theory is formulated to explain observed diffusion behavior. Random walk of particles is followed through a regular lattice with randomly distributed adsorption sites. Comparison of predicted results with experiment shows that the model predicts sorption data well. A modification to the model is proposed to improve prediction of desorption data.
