Abstract
This invention relates to aliphatic polyester resins for use in coatings. More particularly this invention relates to aliphatic polyester resins containing 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD) that exhibit improved scratch resistance when formulated into 1 K automotive clearcoats. These polyesters can be used as the sole resin in the clearcoat binder or in combination with carbamate-functional acrylic resins and/or hydroxyl-functional acrylic and polyester resins.
