Zusammenfassung: | Hydroxy functional urethane compounds comprising the reaction product of a hydroxy functional urethane intermediate with a compound having at least 2 isocyanate groups, wherein the intermediate is represented by the formula: wherein R1 and R2 = hydrogen, alkyl, cycloalkyl or a residue R6-O- or R6-CO-O- with R6; R6 = an alkyl, cycloalkyl or benzylic group having up to 18 carbon atoms; R4 and R5 = hydrogen or alkyl group containing eventually a hydroxyl group; and R3 = alkyl, cycloalkyl or benzylic group eventually containing an ether linkage and/or a hydroxyl group, or HO-CH(R1)-CH(R2)-; and is prepared by reaction of a cyclic 5-ring carbonate with a beta-hydroxy functional, secondary amine. The hydroxy functional urethanes are useful in paints and coatings, particularly for automotive applications. |
