Abstract
A silicone-modified polyester resin and methods for making the resin are described herein. The method includes production of a siliconized intermediate which is then esterified to give a silicone-modified polyester resin. Coating compositions including the silicone-modified polyester resin are provided, and coated articles with the coating composition applied to at least a portion of a surface thereof are also provided.

1-20. (canceled)
A coated article, comprising
- a planar metal substrate;
- a cured coating applied on the planar metal substrate by a coil coating process;
- said coating derived from a liquid silicone-modified polyester coating composition made by a method comprising
- providing at least one hydroxy-functional silicone compound;
- providing at least one hydroxy-functional compound;
- combining the hydroxy-functional silicone compound and the hydroxy-functional compound to produce a siliconized hydroxy-functional polymer;
- esterifying the siliconized hydroxy-functional polymer with at least one carboxylic acid-functional compound or derivative thereof to form the siliconized polyester;
- and
- curing the coating composition on the substrate to form the coated article,
- wherein the coated article demonstrates optimal weathering performance.
