The Influence of Substrate Surface Cleanliness on the Corrosion Resistance of Coating Systems

Article Preview

Abstract:

Water-based coating systems are becoming increasingly popular among consumers due to their simple application and a wide range of colours. A common mistake made by users of these coating systems is neglecting of diagnostics of the corrosive environment and failing to eliminate the factors that cause corrosion aggressiveness. On the boundary of two different environments there can be corrosion products developed and dust particles deposited, which may cause, under certain circumstances, development of deeply hidden corrosion, and thus reduce the level of protection of the substrate. In order to provide long-term protection of the substrate the coating system must be able to eliminate the corrosion agents effectively. In addition to the requirements for aesthetic value set by the consumers, also environmental aspects must be taken into account in the long-term protection of the substrate.
