Influence of layer thickness on corrosion protection properties of multi-layer coating system

Most common method of corrosion protection in shipbuilding is the application of organic coatings, which in addition to the corrosion protection role can have various other requirements depending on the protected part of the structure. In this paper, a solvent-borne coating system dried by infrared (IR) radiation consisted of epoxy primer, epoxy intermediate coat, and polyurethane topcoat, with the difference in achieving rec- ommended primer and topcoat thickness, was studied. Analysed coating system is used for coating ship decks, as well as other marine superstructures such as on offshore facil- ities and wind farms. The results point out better overall protective properties of coating system with thicker topcoat.
