Resumo:
The effect of weathering on the wear resistance of automotive clearcoats has been evaluated. Acrylic-based and urethane-based coatings were exposed in Florida, Belgium and Australia and also under accelerated conditions to SAE J1960 with 0.55 W m -2 borosilicate/borosilicate filtered xenon arc light. Weathering caused a significant reduction in the abrasion and erosion resistance of the clearcoats and large increases in their hardness. Accelerated weathering produced different effects from natural exposure.
