Patent number: 10865324Abstract: Hybrid latex emulsions are disclosed which can be used in the formation of coating compositions having good blush resistance, abrasion resistance, blister resistance, hardness and scratch resistance. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Hybrid latex emulsions of the invention may be prepared by mixing an ethylenically unsaturated monomer component and a stabilizer in a carrier to form a monomer emulsion, and reacting the monomer emulsion with an initiator to form the hybrid latex emulsion. The ethylenically unsaturated monomer component may include an organosilane compound, which may include a reactive organic group and a hydrolysable inorganic alkoxysilane.Type: GrantFiled: March 11, 2014Date of Patent: December 15, 2020Assignee: Akzo Nobel Coatings International B.V.Inventors: Cathy Li, Timothy I. Memmer, Derek Scavuzzo, Daniel Bode

Patent number: 9273226Abstract: Coating compositions are disclosed. In some embodiments, the coating compositions are used to coat substrates such as packaging materials and the like for the storage of food and beverages. The coating compositions can be prepared by reacting an epoxidized vegetable oil and a hydroxyl functional material in the presence of an acid catalyst to form a hydroxyl functional oil polyol, mixing the hydroxyl functional oil polyol (with or without epoxidized polybutadiene) with a functional polyolefin copolymer to form a mixture, reacting the mixture with an ethylenically unsaturated monomer component in the presence of an initiator to form a graft copolymer, and crosslinking the graft copolymer with a crosslinker to form the coating composition.Type: GrantFiled: December 18, 2012Date of Patent: March 1, 2016Assignee: AKZO NOBEL COATINGS INTERNATIONAL B.V.Inventors: Cathy Li, Timothy I Memmer, Daniel Bode, Stefan Posakiwsky

Patent number: 9181448Abstract: Latex emulsions are disclosed which can be used in the formation of coating compositions that are not water sensitive, have good blush resistance and retortability. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Coating compositions of the invention may be prepared by polymerizing at least one ethylenically unsaturated monomer component, a stabilizer comprising a strong acid and an initiator in a carrier to form an emulsion, polymerizing the emulsion with at least one different ethylenically unsaturated monomer component to prepare the composite latex emulsion, and reacting the composite latex emulsion with a neutralizer to form the coating composition. Methods of coating substrates with the coating compositions, and substrates coated with the coating compositions are also disclosed.Type: GrantFiled: December 28, 2011Date of Patent: November 10, 2015Assignee: AKZO NOBEL COATINGS INTERNATIONAL B.V.Inventors: Cathy Li, Tiffany Weidendorf, Timothy I.
