    摘要: The invention provides high solids epoxy-based autodeposition coating materials and a means to obtain the high solids epoxy-based autodeposition coating materials that eliminates/minimizes the need for process solvents. An epoxy pre-polymer is used. The epoxy pre-polymer is combined with ethylenically unsaturated monomer, as an alternative to organic solvent, to yield an epoxy-monomer blend, which may be blended with other coating components and additives. The resulting blend is then dispersed in water with surfactant and the ethylenically unsaturated monomer is polymerized (in the presence of other formulation components) to yield a dispersion. The dispersion may then be used as one component of a coating formulation. The coating formulation can then be applied to materials and cured to form a final coating.

    摘要: Epoxy resins that have one or more functional groups that impart an anionic character to the epoxy resins are prepared. The resulting anionic functionalized epoxy resins may be used to produce high solids, epoxy-based dispersions that are capable of being used as a component of a coating bath which can provide to a coating that may be applied to a surface using a variety of techniques.

    摘要: Disclosed is a release on demand type corrosion inhibitor composition for a metal substrate formed from only non-electrically conductive film forming copolymer(s); a nitrogen containing functional group X, where the group X comprises a pyridine, a dihydropyridine, a pyrrole, an imidazole, or a mixtures thereof; and a metallate anion. The metallate anion binds to a nitrogen in the functional group X by ion pairing. A localized rise in pH is believed to cause release of the anion via a protonation/deprotonation reaction and the released anion suppresses the corrosion formation. The coating composition includes no electrically conductive polymers.
