For more than 100 years, the accepted system for anticorrosive coatings was a combination of lead based paints and oil alkyd layers.
A significant improvement was attained in the 1970s with the introduction of three-coat, high performance system based on zinc-rich primers, pigmented intermediates and light stable polyurethane topcoats for the industrial maintenace market. This three coat system is now the standard anti-corrosive coating system around the world, providing outstanding protection, chemical resistance and weatherability to bridges, petrochemical facilities, power generating plants, waste/water tretment facilities and industrial construction structures.
