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.
Key Words: corrosion, tank lining, epoxy, moisture cure urethane
