A hydroxy functional alkyl polyurea is disclosed having the formula presented in claim 1, wherein R comprises an isocyanurate moiety, biuret moiety, allophonate moiety, glycoluril moiety, benzoguanamine moiety, polyetheramine moiety, and/or polymeric moiety different from a polyetheramine and having an Mn of 500 or greater; wherein each R 1 is independently a hydrogen, alkyl having at least 1 carbon, or a hydroxy functional alkyl having 2 or more carbons and at least one R 1 is a hydroxy functional alkyl having 2 or more carbons; and n is 2-6. Further disclosed is a coating comprising: a film-forming resin; and a hydroxy functional alkyl polyurea crosslinker having the formula presented in claim 4, wherein R 1 is a substituted or unsubstituted C 1 to C 36 alkyl group, an aromatic group, an isocyanurate moiety, biuret moiety, allophonate moiety, glycoluril moiety, benzoguanamine moiety, polyetheramine moiety, and/or polymeric moiety different from a polyetheramine having an Mn of 500 or greater, wherein each R 1 is independently a hydrogen, an alkyl having at least 1 carbon, or a hydroxy functional alkyl having 2 or more carbons and at least one R1 is a hydroxy functional alkyl having 2 or more carbons; and n is 2-6, and when R 2 is a substituted or unsubstituted C 1 to C 36 alkyl group the film-forming resin comprises COOH functionality that reacts with the polyurea to form an ester linkage. Other hydroxy functional alkyl polyurea compounds, polymers made with the same, and compositions comprising the same are also disclosed as are substrates coated at least in part with or formed with any of the compositions described herein. |
