Abstract

Water-based coating systems are becoming more popular with consumers due to their simple application and a wide range of colours. The coating systems, in addition to the requirement of nice finishes, are supposed to provide the sufficient protection of background material from corrosion. According to manufacturers, some modern water-based coating systems do not require any pre-treatment of the underlying material. In this context it is important to understand what influence avoiding underlying material pre-treatment before subsequent application of coating systems could have in terms of future protection against the effects of corrosive environment. At the boundary of two different environments there can be corrosion products developed, which may cause more hidden corrosion development under certain circumstances. The most frequently ignored corrosion agents include dust.For protection of the background material the coating system must eliminate those agents effectively. In addition to the aesthetic requirements from consumers, the protection of the background material must also meet environmental aspects. The question is to what extent coating system manufacturers are able to meet these requirements.
