HEAT-CURABLE COATING COMPOSITION AND ITS USE

摘要

Heat-curable surface-coating agents useful in organically dissolved baking finishes, for powder coating and for cathodic electrocoating contain, as a binder, a mixture of a polyadduct, polycondensate or other polymer which has an average molecular weight &upbar& Mn of from 500 to 10,000 and, per molecule, on average two or more OH and/or NH groups, and a reaction product of a polyamine which contains on average two or more primary amino groups per molecule and a cyclic carbonic acid ester of the formula (I) (I) where R1, R2, R3 and R4 each are hydrogen, methyl or ethyl.
