Patent number: 11932775Abstract: A curable coating composition is provided having multi-functionalized acrylic copolymer and silicone imine resin curing agents. The acrylic copolymer of the curable coating composition has, in polymerized form, epoxy functionalized groups and cure compatibility groups and the silicone imine forms an amino-functional silicone in the presence of water. The coating compositions are useful in the field of superior weatherable and durable coatings and are useful to replace isocyanate-containing polyurethane based coatings. Also provided are coated articles produced from the curable composition.Type: GrantFiled: July 17, 2019Date of Patent: March 19, 2024Assignees: Dow Global Technologies LLC, Dow Siliicones CorporationInventors: Alan M.
