Paper Abstract

The mechanical properties and surface shapes of the composited polyurethane coatings were tested by nanoindentation. Treated by high-temperature ageing and solarization, the composited polyurethane coatings were tested to investigate the different changes between the upper and the lower surfaces. The results show that the mechanical properties of the upper and the lower surfaces of the composited polyurethane coating hardly changed although it had been yellowing after 168 hours solarization ageing. But both the modulus and hardness of the upper and lower surfaces increased after 168 hours ageing at 75°C, especially for the lower polyurethane surface.
