Polyester resin for powder coating having excellent weather resistance and stain resistance and powder coating composition containing the same

摘要

The present invention relates to a polyester resin for powder coating having excellent weather resistance and fouling resistance, and a powder coating composition containing the same. More specifically, two kinds of very different weather and fouling resistance having carboxyl group and hydroxyl group at the same time It relates to a polyester resin having a functional group of and a powder coating composition containing the same. The resin may be mixed with the powder coating composition to maximize weather resistance and stain resistance, and may also obtain good results in leveling, storage stability, and mechanical properties.
