Abstract:
1. A process for continuously coating a metal or metal strip by the coil coating process; comprising the steps of applying a solution comprising a polysilazane or a mixture of polysilazanes of the formula (I) where R′, R″ and R′″ are identical or different and independently of one another are hydrogen or an unsubstituted or substituted alkyl, aryl, or (trialkoxysilyl)alkyl radical, n being an integer such that the polysilazane or a mixture of polysilazanes has a number average molecular weight of 150 to 150,000 g/mole, in at least one solvent and at least one catalyst to the metal or metal strip to form a coating on the metal or metal strip and curing the coating on the metal and metal strip at a temperature of 150 to 500° C. by using IR or NIR radiation, further where the curing time is 10-120 seconds.
