  • Patent number: 9695322
    Abstract: A process for coating a metallic surface of a metallic substrate comprising applying, an organic, anionically, cationically or radically curable anticorrosive composition, to the metallic surface, wherein said anticorrosive composition is a dispersion or solution containing at least two components that are at least partially anionically, cationically or radically curable, wherein at least one monofunctional monomer or monofunctional oligomer is present, a photoinitiator, and first organic corrosion inhibitor.
    Type: Grant
    Filed: January 6, 2012

  • Publication number: 20060228481
    Abstract: Disclosed is a method for coating surfaces of metallic substrates with an organic, anionically, cationically, or/and radically hardenable anti-corrosive composition that represents a dispersion or solution containing at least two components selected among the group of monomers, oligomers, and polymers which can at least partly be anionically, cationically, or/and radically hardened, the content of at least one monofunctional monomer or/and oligomer in said anti-corrosive composition ranging between 1 and 50 percent by weight. The inventive anti-corrosive composition further comprises at least one photoinitiator used for anionic, cationic, or/and radical crosslinking, and a first, organic corrosion inhibitor. The anti-corrosive composition is applied to the metallic surfaces at a wet film thickness ranging from 1 to 25 micrometers, is optionally dried, and is then anionically, cationically, or/and radically hardened in order to obtain an anti-corrosive coating.
