摘要：Anti-corrosive coatings on surfaces of metals other than aluminium, especiallyon galvanised steel, are produced by drying and heating of a water-based coating agentwhich contains chromium(VI) and a water-soluble or water-dispersible layer-formingorganic polymer, the coating agent used additionally containing a water-soluble organiccompound of a boiling point above 100 DEG C, the organic compound having at least one-CH2OH group and/or at least one =CHOH group and - if only one of these groups ispresent in the molecule - at least one ether group (-O-). Organic compounds from thegroup comprising ethylene glycol, diethylene glycol, triethylene glycol, ethylene glycolmonomethyl ether, diethylene glycol monomethyl ether, propylene glycol, dipropyleneglycol, butanediol, hexanediol or glycerol are preferred and are used in a concentrationfrom 0.1 to 20 g/l.
