This paper is a case study on a 100% solids epoxy penetrating sealer being used as a tie coat between a tightly adhered latex acrylic and aliphatic polyurethane.
Adhesion performance is required for every coating system. The adhesion between coatings and substrates is one of the most critical determining factors in the overall success of any coating material. Material design and formulation are key components of high-performance coatings and rely heavily on the accurate measurement and evaluation of adhesion in the coating systems.

Inorganic zinc (IOZ) silicate coating was previously applied to partially fabricated low alloy, 21/4 Cr-1MoV, high temperature, hydrogen, reactor vessels for long-term storage corrosion protection prior to final welding and post weld heat treatment (PWHT) at 690-720°C (1274-1328°F). The need for complete coating removal to mitigate the known embrittlement and weld cracking that can occur after welding and PWHT led to the development of a novel, environmentally friendly method to remove IOZ to trace levels below 1 ppm.
A test methodology is shown for field application of electrochemical impedance spectroscopy (EIS). The method utilizes low-cost, accessible materials to secure a temporary solution cell to the infrastructure’s coated surface. A laptop computer provides the power source and operating system for the mobile potentiostat during EIS data collection. This data provides a quantitative measure of the coating condition. The objective of this work is to incorporate EIS testing into standard coatings inspection to estimate remaining service life for the intact coating, which improves coatings maintenance planning for facility owners.
