Patent number: 10106689Abstract: The object of the underlying invention consists of an acidic aqueous metal pretreatment solution that comprises amino-functional organosilanes and organophosphorus acids. These types of metal pretreatment solutions effectively reduce temporary corrosion when applied to metal surfaces and in addition confer good adhesion properties for subsequently coated organic lacquers. The invention consequently also encompasses a process for the treatment of metal substrates, especially selected from zinc and zinc-coated steel substrates, wherein metal pretreatment solutions of this invention are applied.Type: GrantFiled: February 4, 2016Date of Patent: October 23, 2018Assignee: Henkel AG & Co.

Patent number: 9909227Abstract: The invention relates to a method for the anti-corrosive pretreatment of tinplate, in which an anti-corrosive primer coating is applied in a single step, said primer coating effectively preventing the shiny metal surface of the pretreated tinplate from turning black when the pretreated tinplate of the invention that is provided with a topcoat is in contact with liquids releasing or containing sulfur compounds and with food containing protein. In the disclosed method, the tinplate is anodically polarized in an electrolyte containing silicates of formula M2O.nSiO2, where M is an alkali metal ion or quaternary ammonium ion and n is a natural number between 0.8 and 7. Tinplate pretreated according to the invention can be used in particular for the production of food-safe packaging such as beverage cans or tin cans.Type: GrantFiled: March 13, 2013Date of Patent: March 6, 2018Assignee: Henkel AG & Co.

Patent number: 9777165Abstract: The present invention relates to an alkaline aqueous composition on the basis of water glass and organosilanes with non-hydrolysable substituents which have a primary amino group in the substituents, for providing corrosion-protected coatings on metal surfaces which convey good reshaping properties in metal processing. For the desired functionality, the compositions according to the invention contain the organosilane and the water glass in a predetermined ration. The invention further relates to a method for pre-treating metal surfaces using the alkaline aqueous compositions, which method provides excellent results with regard to corrosion protection, varnish adhesion and reshapability, particularly on aluminum and on steel strips provided with aluminum alloy metal coatings.Type: GrantFiled: March 19, 2015Date of Patent: October 3, 2017Assignee: Henkel AG & Co.

Patent number: 8425170Abstract: The present invention relates to a method for the bonded adhesion, or connection, of a plurality of wire-shaped individual elements into an arrangement, particularly into a wire band, wherein the adjacent individual elements have predetermined breaking points allowing for the mechanical removal of the individual elements. The bonded adhesion is brought about according to the invention utilizing a two-layer system on the basis of acrylate resins consisting of an inner coating (A) and of an outer coating (B), wherein the inner coating (A) has a lower hardness, than the outer coating. In a further aspect the invention also comprises arranging a plurality of wire-shaped individual elements through such a bonded connection, particularly a wire band.Type: GrantFiled: April 15, 2011Date of Patent: April 23, 2013Assignee: Henkel AG & Co.
