Abstract: The invention relates to a process for coating metal strip in the coil coating process. The coating materials employed consist of:a) 3 to 50% by weight, preferably 20 to 40% by weight, of polyester imide resins, the 20 to 60% by weight solutions of which possess viscosities from 90 to 4,000 mPas at 23.degree. C. and the hydroxyl values of which are in the region from 50 to 300,b) 3 to 40% by weight, preferably 10 to 30% by weight, of pigments and/or fillers,c) up to 3% by weight of suitable auxiliary substances and additives andd) 10 to 90% by weight, preferably 20 to 60% by weight, of one or more organic solvents,the sum of a), b), c) and d) being 100% by weight. The invention further relates to the use of the metal strip produced by the process according to the invention for production of exhaust components.

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.
