This book describes the processes of photophysics and photochemistry that lead to the weathering of exposed surfaces. The parameters of exposure, measurements in assessment of weathering conditions, climatic conditions, methods of outdoor exposure, laboratory degradation studies, weathering cycles, sample preparation, weathering data interpretation, lifetime prediction, artificial weathering versus natural exposure, effect of weathering on material properties, testing methods for weathered specimens, data on 43 specific polymers, effect of additives on weathering, weathering of compounded products, stabilisation / stabilisers, biodegradation, recycling, environmental stress cracking, interrelation between corrosion and weathering, and weathering of stones are included. Examples discussed include coatings (including vehicle paint) and sealants.
