Photochemical degradation of alkyd paints

Abstract

Alkyd paints make up two thirds of the paints made in Australia and in fact three quarters of the paint used by the Armed Services is alkyd based. It can be seen, therefore, that increasing the service life of alkyd paints would effect considerable savings both to our defence effort and to the community at large. Photodegradation is a major cause in the reduction of a paints service life. It may cause chalking, checking, cracking, blistering and embrittlement and these in turn may lead to loss of adhesion. This could allow water, oxygen, air pollutants and grit to attack the underlying substrate causing corrosion and possibly loss of expensive equipment.
