Patent number: 6586516Abstract: The present invention relates to an aqueous coating composition having low volatile organic compounds (VOC) and producing a coating having excellent durability and resistance properties. The coating composition contains acetoacetate functional polymer and divalent metal ions. Coating compositions of the present invention are particularly useful in ink, polish and coating compositions where a tough, resistant coating is required. The coating composition can be used on various substrates such as floors, walls wood, metal, plastic, stone, paper, leather and concrete.Type: GrantFiled: October 4, 1996Date of Patent: July 1, 2003Assignee: Rohm and Haas CompanyInventors: Mark Alan Kesselmayer, Theodore Tysak, Matthew Stewart Gebhard, Min-Chi Tsai von Trentini

Patent number: 5908877Abstract: A water dispersible powder composition is provided. The powder composition contains at least one film-forming polymer having at least one functional group and at least one reactive component that reacts to form a non-ionic bond with the polymer functional group following dispersion of the powder composition in water. The reaction between the polymer particles in the admixture and the reactive component renders the resulting coating water-resistant. The powder composition of this invention is useful for producing water-resistant coatings.Type: GrantFiled: May 7, 1997Date of Patent: June 1, 1999Inventors: Xiaohong Ci, David RIchard Amick, Richard Foster Merritt
-
Patent number: 5856611Abstract: A zirconium catalyzed transesterification process for preparing synthetic wax monomers is disclosed. The monomers are useful in a wide range of polymers.Type: GrantFiled: October 15, 1997Date of Patent: January 5, 1999Assignee: Rohm and Haas CompanyInventors: Francis William Schlaefer, Andrew William Gross
-
Patent number: 5814374Abstract: An aqueous coating composition having low VOC is provided. The invention provides excellent hardness and resistance properties in films formed from binders having glass transition temperatures below ambient temperature. The improvement in film properties comes from the binding of functionalized polyvinyl alcohol to a complementary functionalized latex binder. The low VOC compositions of this invention are useful for a variety of coatings including paints, stains, varnishes, mastics and adhesives.Type: GrantFiled: June 19, 1996Date of Patent: September 29, 1998Assignee: Rohm and Haas CompanyInventors: Asare Nkansah, Stewart Orlyn Williams, Richard Foster Merritt
