The invention relates to amino and hydroxy-functional polyesters, wherein the amine is in the form of aspartic acid esters functionality, and wherein the amino and hydroxy-functional polyester has (a) a molecular weight (Mn) of at least about 500, (b) an acid value of about 5 or less, (c) a hydroxyl value of about 30 or more, and (d) an amine value of about 30 or more, and (e) an amine functionality of less than 1.8. Preferably, the compound includes molecules having on the average: at least 1 secondary amino group as an aspartate, and/or at least 1 hydroxy group, and an average total functionality of about 1.8 or higher. More preferably, the molecular weight of the amino and hydroxy-functional polyesters is between 204 and 10,000 and preferably between 482 and 5000.
An amino and hydroxy-functional polyester, wherein the amine is in the form of aspartic acid esters functionality, and wherein the amino and hydroxy-functional polyester has
A method for preparing a polyester based amino and hydroxy-functional compound, comprising the preparing a hydroxyl functional polyester comprising at least one of:
A coating composition comprising the following components in parts by weight (pbw):
A low molecular weight amino and hydroxy-functional polyester derived from the reaction of unsaturated oligoesters and mono primary amine, the unsaturated polyesters having on average at least one and a maximum of 1.8 fumarate or maleate units, and wherein the amino functionality is between 0.8 and 1.8 groups per molecule in the form of a secondary amine as aspartic acid ester.
