Maintenance of Paint Systems

Abstract

In the long run, all paint systems develop defects. Examples are mechanical damage, loss of gloss, chalking, discolouration, cracking, flaking and chemical and biochemical degradation. Such defects are caused either by atmospheric attack (including attack by pollutants), or attack by water (e.g. sea water), chemical and mechanical influences. They cause degradation of the substrate, such as corrosion of metals, which, if no specific measures are taken, can even lead to mechanical failure of the (coated) structure.
