| Résumé : |
The possibility of a long lasting durable coating that can retain its initial properties has always fascinated paint and polymer technologists. The clearcoats which are applied today on automotive vehicles is designed to provide a brilliant high gloss appearance with good mechanical, chemical and durability properties.
A vehicle gets subjected to many damaging elements in the environment which contribute to scratch and mar damage of the coatings. The accumulative effect of mars, scratches and chipping deteriorates the appearance of the vehicle. Along with this, the chemical degradation occurring due to the environmental factors viz. weathering, high temperature and air pollutants causes changes in the coating's physical and performance properties. These aspects affect the aesthetic appeal of the coating system and have resulted in new challenges for the coating technologist.
The present paper looks at the mar and scratch resistance behavior of coatings and detailed analysis made to characterize the defect and develop a good mar/scratch resistant coating. |
