ABSTRACT:
A thermosettable coating composition comprises a hydroxy group-containing polyurethane, polyurea or polyurethane/polyurea polymer, an amino cross-linker and optionally, a catalyst and/or solvent. The polymer is obtained by self condensation of an hydroxyalkyl carbamate compound or condensation of such compound with a polyol and/or a polyamine. An applied coating of the composition is cured by heating to an elevated temperature, e.g., from about 200.degree. to about 400.degree. F. (about 93.degree. to 204.degree. C.).
