Abstract: An electrolysis device includes two electrolysis units, which each includes two end plates. The electrolysis units each includes an intermediate plate approximately or exactly in the middle between its end plates and each includes a stack of series-connected electrolysis cells between the intermediate plates and the end plates. Each stack of electrolysis cells includes two electrodes, at which an electrolysis liquid is partially electrolytically split, so that the remaining electrolysis liquid is admixed with a respective electrolysis gas in the area of the two electrodes after the electrolytic splitting. The end plates are electrically connected to one another at least in pairs. The electrolysis device includes a rectifier unit, which provides two potentials (P1, P2) via two outputs, each output being electrically connected to one terminal of the intermediate plate of the one electrolysis unit and to one terminal of the intermediate plate of the other electrolysis unit.

Abstract: A water-based adhesive film-forming cover composition including: (i) at least one film forming polymer; (ii) at least one lower crystallinity first polynitroso compound; (iii) at least one higher crystallinity second polynitroso compound; (iv) at least one crosslinking agent; and (v) water as a carrier liquid; a bonding system including a combination of: (a) a water-based primer component; and (b) the above water-based cover component; a process for manufacturing the above bonding system; and a process of manufacturing a bonded article with the above bonding system. A bonded article, having a bonding line made from the above bonding system disposed between metal and rubber substrates, exhibits excellent stability against an aqueous urea-solution at temperatures of up to about 95° C.

Abstract: Disclosed is an aqueous adhesive composition which comprises an admixture of: (a) a first aqueous composition comprising, (i) one or more film forming polymers, (ii) one or more lower crystallinity polynitroso compounds, (iii) one or more higher crystallinity polynitroso compounds, and (iv) one or more bismaleimide-containing monomers; and (b) a second aqueous composition comprising (i) an aqueous dispersion of at least one phenolic resin which is a condensation product of a phenol and formaldehyde, wherein the aqueous dispersion is stabilized by at least one polyacrylate; (b) one or more latices formed from one or more halogenated polyolefins; and (c) one or more metal oxides.
