  • Publication number: 20200299518
    Abstract: The present invention relates to a method for providing electrically insulating and anti-corrosive coatings on electrical steel strip by using a phosphate-free aqueous dispersion. Furthermore, the invention relates to such an aqueous dispersion which is particularly suitable for providing electrically insulating and anti-corrosive coatings on electrical steel strip. The aqueous dispersion of the present invention is substantially free of phosphates and organic compounds and comprises silicates dissolved in water as an inorganic binder which forms the coating, and a mixture of oxide pigments of the elements titanium and aluminum. The subject matter of the invention also comprises a laminated electrical steel strip which is made from the electrical steel strip produced in the method according to the invention or from electrical steel strip coated with an aqueous dispersion according to the invention.

  • Patent number: 10315216
    Abstract: The present invention relates to a water-based can inner coating based on a copolymer or a copolymer blend of at least one aliphatic and acyclic alkene having at least one ?,?-unsaturated carboxylic acid in water-dispersed form, wherein the can inner coating contains a water-soluble curing agent selected from inorganic compounds of the elements Zr and/or Ti, so that the need for using organic hardener systems can be largely avoided. The present invention further relates to a method for the internal coating of tin cans or aluminum cans, in which the previously mentioned can inner coating is directly applied to the metallic inner surfaces of the cans and cured without any need to carry out a conversion treatment for improving coating adhesion of the inner surfaces of the cans.

  • Patent number: 9889468
    Abstract: The present invention relates to a method for manufacturing coated can lids from aluminum strip, and is based on the finding that flexible, easily formable coatings having high abrasion resistance result from the use of water-based lacquers containing a copolymer or a copolymer mixture of at least one aliphatic, acyclic alkene with at least one ?,?-unsaturated carboxylic acid in water-dispersed form, and a curing system. In a preferred embodiment of the method, the application of a primer coating can be dispensed with entirely when water-soluble compounds of the elements Zr and/or Ti in the lacquer are used as the curing system.
