Abstract
Catalysts useful for low-cure powder coating compositions are disclosed, having the structure (I): wherein R1 is an organic radical having 6 to 25 carbon atoms; each R2 is independently a multivalent hydrocarbon group having 1 to 20 carbon atoms; Y is each R3 and R4 are independently alkyl or aryl groups having 1 to 12 carbon atoms; each Z is independently oxygen or nitrogen; R5 is absent when Z is oxygen and R5 is hydrogen, an alkyl or aryl group having 1 to 20 carbon atoms, or (Y)a —R2— when Z is nitrogen; a, b, and c are integers; each X is independently S, O, or N(R6); each R6 is independently hydrogen or an alkyl or aryl group having 1 to 12 carbon atoms; and P is a polymeric material.
