Traditional internal lining schemes for the storage/transport of crude oil & refined fuels may no longer be appropriate. The aggressive nature of crude oil (high temp. & more sour), high purity refined products & increased use of biofuels demand better linings & more certain test results. The focus of this paper is to review the trends in test methodology from the early 1990’s to present.
Splash and immersion zones on offshore installations are areas that are exposed to extremely aggressive environments due to the effects of sea water, tides, wind, waves, and/or ultraviolet radiation. Various certifications such as NORSOK(1) exist to help guide customers select a coating based on its corrosion resistance performance. Despite the necessity of these standards, it is helpful to understand that other properties such as substrate surface and cure conditions can greatly effect performance of the coatings. In this paper, we will compare adhesion of two coatings to different substrate surface conditions while both coatings will be cured in two different environments. Our goal is to investigate the effect of curing environment of coatings on adhesion to the substrate.
