Traditional tank lining coatings are costly, have high VOC content and generally require a high film thickness of multiple coats. This paper presents the results of testing a new type of coating system applied to the inside of tanks, exposed to corrosive environments. This new coating system has been extensively tested in the laboratory and field applications. The field applications include several holding tanks, where the products for storage vary from hydrocarbon to high salinity solutions. The coating system consists of a low VOC rust converting water based primer and a high solids moisture cure urethane coating which are applied at a much lower film thickness then the traditional tank lining coating systems, yet provides the same or better corrosion protection.
