    摘要： A crosslinking agent having reactive benzoxazine groups is provided. The crosslinking agent is an ungelled reaction product of aminoplast resin, a polyhydric aromatic compound, and at least one compound having active hydrogen groups reactive with aminoplast resin which is selected from at least one of: (i) compounds having the structure (I): where X is aromatic; R1, R2, and R3 each independently represents H, (cyclo)alkyl having from 1 to 12 carbon atoms, aryl, alkaryl, aralkyl, or an active hydrogen-containing group; (ii) compounds having structure (II) or (III): where R′ and R″ each independently represents an aromatic group or an alkyl group having 1 to 12 carbon atoms; and (iii) compounds different from (i) and (ii) and having a melting point of at least 80° C. Curable powder coating composition and multilayer composite coating compositions are also provided, as well as coated substrates.

    摘要： Low-cure powder coating compositions are disclosed, comprising at least one epoxy-containing resin and/or at least one siloxane-containing resin, and at least one material having the structure 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 8 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 and b are integers; a is at least 1; b is 1 to 3; and (b) at least one epoxy-containing resin and/or at least one siloxane-containing resin. The material can optionally be reacted with an acidic hydrogen-containing compound. Some compositions are curable without using crosslinking agents or accelerators. Methods for coating a substrate using these compositions, the coated substrates, and additional catalysts useful for the same purpose are also disclosed.
