The purpose of this project was to carry out a systematic and comprehensive electron spectroscopy for chemical analysis (ESCA) study of the weathering of selected organic coil coatings of well-defined composition. Other methods of analysis were used to augment the ESCA data: secondary ion mass spectroscopy (SIMS) and laser induced ion mass analysis (LIMA) were used to provide structural information on the degradation products which appear on the surface of coatings during weathering; Fourier transform infrared analysis (FTIR) was used to provide information on the chemical changes which occur within the bulk of the coating. The objective of all analyses was to attempt to elucidate the complex mechanisms of the weathering of such coatings, thereby assisting in the development of more durable coatings. Furthermore, since changes in surface chemistry can be observed long before any physical changes can be detected, it was considered that the use of these techniques might provide the basis for a more rapid and accurate method of assessing the long-term durability of organic coil-coatings.
