Acrylic Melamine Coating Compositions Containing Polymer-Bound Hindered Amine Light Stabilizer Acrylic Resins
Unique acrylic high solids coating resins with attached hindered amine light stabilizer (HALS) groups have been developed. They are readily prepared by reacting a hydrazide functionalized HALS with acrylic polyol resins containing anhydride and/or epoxy groups. As a result, the HALS moiety is rendered nonvolatile and nonextractable. The attachment of the HALS to the acrylic polymer allows the use of an unsubstituted HALS in acid catalyzed systems. Acrylic melamine coatings prepared from polymer-bound light stabilizer resins exhibit outstanding weatherability ...
