Abstract
The aim of the present study was to find and develop a sensor to evaluate the weathering rates of wood coatings during natural and artificial weathering using a material of known and controlled rate of decomposition. This was achieved by the use of a coating based on poly (vinyl acetate) copolymer binder in combination with Fe2+ as redox catalyst. It was possible to model the decomposition rates by dry film thickness, Fe2+ concentration and addition of pigments. One application of this sensor for wood coatings is to indicate the need of maintenance.
