  • Patent number: 7776448
    Abstract: An aqueous composition for pretreating and depositing a coating on metal substrates is provided. The coating composition includes from about 1,500 to about 55,000 ppm based on the aqueous composition of a Group IIA dissolved metal ion, from about 100 to about 200,000 ppm based on the aqueous composition of a dissolved complex metal fluoride ion wherein the metal atom is selected from Group IIIA, Group IVA, Group IVB metals, Group VA, Group VB metals; and water. The composition is free of Group IIA metal fluoride precipitate achieved by including in the composition a complex metal salt different than the salt associated with the complex metal fluoride ion, with the complex metal salt being capable of complexing free fluoride ions to prevent a precipitation reaction.

  • Patent number: 7754787
    Abstract: Curable film-forming compositions comprising a film-forming resin and an organic sol of particles are provided. The sol of particles may be prepared by providing a suspension of particles in an aqueous medium; adding a first organic liquid compatible with the aqueous medium to form an admixture; reacting the particles with a first and a second modifying compound; adding a second organic liquid compatible with the liquid portion of the admixture wherein the second organic liquid is different from the first organic liquid; and maintaining the admixture at a temperature and pressure and for a time sufficient to substantially remove the water and the first organic liquid. The film-forming resin comprises an active hydrogen-functional polymer having low functionality; i.e., a functional group equivalent weight greater than 380 g/equivalent, and a crosslinking agent, yet surprisingly offers outstanding mar and scratch resistance.
