Abstract
A primer coating composition for a metal substrate is described. The primer has a suitable binder and is characterized in that there is at least one semiconductor photocatalyst dispersed throughout the primer coating composition. A process of coating a metal substrate is also described. The invention extends to the use of a semiconductor photocatalyst as a top-coat to primer adhesion promoter or as a primer to top-coat delamination inhibitor in a primer coating composition.
