Patent ID: 8247037

Claim:
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) —(SiR′R″—NR′″) n — (1) 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.
