Over the years there has been considerable discussion and confusion regarding so-called “surface tolerant paints”. Claims made for substrate tolerance and performance vary widely and thus a program of work was undertaken to evaluate hydrocarbon modified epoxies, and flexibilized epoxies, on various substrates from St2 hand prepared heavily corroded pitted steel, to re-oxidized Sa2½ blasted steel and Sa2½ blasted steel, as well as aged thermoplastic coatings.
