Change in a coating surface, or bulk, during weathering is the accumulation of repeated, random, nanoscale erosion or chemical events that may be modelled using Monte Carlo techniques. Multi-phase coatings, including pigments, may be simulated, as well as polymers that change their sensitivity to degradation during weathering. The results of the Monte Carlo model are compared with those of macroscopic properties, such as, gloss, fracture toughness, and wetting contact angle. Simulated properties change through the lifetime of the coating in ways that are consistent with published results. Seemingly complicated changes in properties may be described by repeated simple, random processes. Copyright OCCA 2005.
