Title

NEW STRATEGIES FOR PREDICTING THE PROTECTIVE INTERNAL COATINGS PERFORMANCE BEFORE USING IN SERVICE

Pages

  81-94

Abstract

 Anticipating the protection performance of coatings, before using them in the field is a significantly factor. Quality control testing in accordance with the international standards is time-consuming, and the results are qualitative.In this research, a new strategy for determining vessel and tank internal coating performance has been developed, which is a fast assessment method with quantitative results. Some tests such as hot water soak, Immersion and electrochemical spectroscopy, impedance in high temperature conditions, and dry and WET ADHESION have been selected as critical tests which were done on four different commercial EPOXY COATING samples. The reaction of stoichiometric mixture of two components (Epoxy and hardener) and the effect of physical properties of polymer matrix on the coating resistance and CORROSION control have been investigated by using FTIR measurement and thermo gravimetric analysis (TGA).The results of TGA and FTIR have shown that the selected coatings are different in terms of chemical structures and glass transition temperature (Tg). The results of mechanical and electrochemical tests have confirmed that the protective performance of these coatings is related to their chemical structures and Tg of polymer matrices. On the other hand, this new strategy makes it possible to quantitatively predict the protective performance of the coating, in a short time. The results of tests on the four EPOXY COATINGs are demonstrated that although all of the coating samples are epoxy-based and suitable for using as recommended by the manufactures, their protective performance and resistance against electrolyte diffusions are considerably variant.
