| titleOfInvention | Thermosetting Coating Compositions With Improved Hardness and Curability |
| abstract | The present invention provides a crosslinkable polyester oligomer composition comprising one or a mixture of oligomers of formulas (a) and (b):n n n Formula an n n n n n n n Formula bn n n n n n n n In the above formula,n n n R is a residue of at least one aliphatic, cycloaliphatic or mixed aliphatic / aromatic polycarboxylic acid having from 2 to about 20 carbon atoms,n n n R 1 is a residue of at least one aliphatic, cycloaliphatic or mixed aliphatic / alicyclic polyol having from 2 to about 20 carbon atoms,n n n A is an expression Is a radical ofn n n B is an expression Is a radical ofn n n R 4 is H, OH, halogen or an organic radical containing 1 to 4 carbon atoms,n n n R 5 is a direct bond or an organic radical containing 1 to 20 carbon atoms,n n n R 6 is an organic radical containing 2 to 20 carbon atoms,n n n n is an average of 0 to 2,n n n P is a number from about 0.5 to 2,n n n The composition is also characterized by a number average molecular weight of about 250 to about 1,000 and a polydispersity of less than about 2.0.n n n The present invention also provides curable blends of these polymer oligomers with other polymers such as polyesters, alkyds, acrylic polymers and the like that can be further used to prepare curable coatings and paint formulations, and also provide crosslinking catalysts, fillers, pigments. And other ingredients, such as the like. Upon curing, the coatings of the present invention exhibit improved physical and chemical properties compared to cured coatings that do not contain a polyester oligomer component. |
