A hydroxy functional alkyl polyurea having the formula set forth in claim 1 is disclosed, wherein R is an isocyanurate residue, a biuret residue, an allofonate residue, a glycoluril residue, a benzoguanamine residue, a polyetheramine residue, And/or a polymeric moiety different from the polyetheramine and having an Mn of 500 or more; Each R 1 is independently hydrogen, an alkyl having at least one carbon or a hydroxy functional alkyl having at least two carbons, wherein at least one R 1 is a hydroxy functional alkyl having at least two carbons; n is 2-6. In addition, a coating comprising a film-forming resin and a hydroxy functional alkyl polyurea crosslinking agent having the formula shown in claim 4 is disclosed, wherein R 2 is a substituted or unsubstituted C 1 to C 36 alkyl group, an aromatic group. , An isocyanurate moiety, a biuret moiety, an allofonate moiety, a glycoluril moiety, a benzoguanamine moiety, a polyetheramine moiety, and/or a polymeric moiety different from the polyetheramine and having an Mn of 500 or more; Each R 1 is independently hydrogen, an alkyl having at least one carbon or a hydroxy functional alkyl having at least two carbons, wherein at least one R 1 is a hydroxy functional alkyl having at least two carbons; n is 2 to 6, but when R 2 is a substituted or unsubstituted C 1 to C 36 alkyl group, the film-forming resin includes a COOH functional group that reacts with the polyurea to form an ester linkage. Also disclosed are other hydroxy functional alkyl polyurea compounds, polymers made using the same, and compositions comprising the same, and likewise disclosed are substrates that are at least partially coated or formed using any of the compositions described herein. |
