The performance and durability of a number of industrial coating systems have been studied for two and a half years at five weathering sites in the industrial belt of Shuaiba Area, Kuwait, in the Arabian Gulf. The outdoor weathering performance of eleven coating systems was related to the prevailing industrial atmospheric conditions, and comparison made to their behaviour under laboratory accelerated conditions. The coating systems studied included acrylic enamel, micaceous iron oxide epoxy, alkyd enamel, alkyd gloss, chlorinated rubber, polyurethane, and water-based acrylic. Experience in Kuwait has shown that with the longer hours of strong sunshine and ambient temperatures, as well as the chemical content of the atmosphere (e.g. O3, SO2, NOx, NH3, Cl), dust retention and sandstorm, degradation of coatings has tended to be faster than in Western countries for which most of these generic coating systems were developed.

Two accelerated test methods were used to evaluate the protective properties of the above mentioned coatings when applied to steel panels.
