Electrochemical Impedance Evaluation Of Coating Under Simulated Splash Zone Condition

One of the requirement for a high performance coating to be applied to an offshore structure is to conduct and withstand long term accelerated weathering test for 4200 hours. However, in some cases, the offshore structure’s coating may be experiencing premature failure, even though it meets the acce...
