ABSTRACT:
The invention relates to a process for coating metal strip by the coil coating process using coating materials consisting of high temperature resistant systems (polyesterimides, polyamidocarboxylic acids, polyamidimides, polyhydantoins and polybismaleimides), pigments and/or fillers, suitable auxiliary substances and additives as well as solvents or solvent mixtures. The coating material is used in a one-coat or two-coat application, only polyesterimides and polyhydantoins being used for the primers as high temperatures resistant systems, while any of the high temperature resistant systems listed are used in the topcoat.
The metal strip coated in this manner possesses good formability, good hardness, outstanding anticorrosion characteristics, outstanding resistance to chemicals, solvents, water, oil, shock and prolonged high temperatures, outstanding adhesion and resistance to stone impact, and is particularly suitable for the production of exhausts, silencers, exhaust air ducts, furnace and radiator claddings, grill utensils and other components exposed to high temperatures.
