| titleOfInvention | Thermoset coating compositions having improved hardness and curing properties |
| abstract | The present invention provides an amino curable polyester oligomer composition having low viscosity and a narrow molecular weight distribution comprising one or a mixture of oligomers (a) and (b), wherein R is the residue of at least one aliphatic, cycloaliphatic or mixed aliphatic/aromatic polycarboxylic acid having from 2 to about 20 carbon atoms, R1 is the residue of at least one aliphatic, cycloaliphatic or mixed aliphatic/cycloaliphatic polyol having from 2 to about 20 carbon atoms, A is a radical of formula (I); B is a radical of formula (II), wherein R4 is H, OH, halogen or an organic radical containing 1 to 4 carbon atoms, R5 is a direct bond or an organic radical containing 1 to 20 carbon atoms and R6 is an organic radical containing 2 to 20 carbon atoms, n is a number averaging from greater than 0 up to less than 2 and P is a number averaging from about 0.5 up to less than 2, said composition further characterized by a number average molecular weight in the range of from about 250 to about 1,000 and a polydispersity of less than about 2.0. The invention also provides for curable blends of these polyester oligomers with other polymers such as polyesters, alkyds, acrylic polymers and the like, which may be further used to prepare curable coating and paint formulations, and also may contain other ingredients such as a cross-linking catalyst, fillers, pigments and the like. When cured, the coatings of this invention exhibit improved physical and chemical properties when compared with cured coatings which do not contain the polyester oligomer component. |
