SCRATCH RESISTANT THERMOSETTING COATING COMPOSITIONS

Abstract:

This invention relates to a carbamate functional thermosetting coating with a composition comprised of a carba-mate-functional acrylic and/or polyester polyol and an alkylated melamine-formaldehyde cross linker modified by an aliphatic polyester and an alkylated melamine. The polyester polyol is made of monomers including a 2,4,4-tetraalkylcyclobutane-1,3-diol and an aliphatic diacid. These polyester polyols can be used in blends with hydroxyl-functional or carbamate-functional acrylic resins or serve as the primary film former in a coating formulation.
