Abstract: A method of coating surfaces of plastic or metal, which comprises treating the plastic or metal surface in question with an aqueous dispersion comprising (A) at least one ethylene copolymer having a molecular weight Mn in the range from 2000 to 20 000 g/mol, selected from ethylene copolymers comprising as comonomers in copolymerized form (a) 15.5% to 19.9% by weight of at least one ethylenically unsaturated C3-C10 carboxylic acid and (b) 80.1% to 84.5% by weight of ethylene, (B) at least one base, in one step and subsequently providing in at least one further step the metal or plastic surface in question with at least one further coat.

Abstract: Procedimiento para la manipulación de soluciones acuosas de ácido metanosulfónico (MSA) con una concentración del 50 al 99 % en peso de MSA, en dispositivos en los que la solución acuosa de MSA está en contacto con superficies de acero, tratándose en el caso del acero de aceros austeníticos con un contenido de cromo del 15 al 22 % en peso y un contenido de níquel del 9 al 15 % en peso y en donde la temperatura del MSA durante la manipulación es inferior a 40 °C, caracterizado porque el contenido total de cloro en la solución acuosa de MSA es inferior a 25 mg/kg.

Abstract: In an example of a method for recovering lead from a mixed oxidized lead material, methane sulfonic acid is selected as a leaching acid for the mixed oxidized lead material. The mixed oxidized lead material is exposed to a solution including the methane sulfonic acid, which leaches lead from any of a lead oxide or a lead carbonate in the mixed oxidized lead material, and generates a liquid leachate including a lead- methane sulfonate salt. The liquid leachate is purified, and lead is recovered from the purified liquid leachate using electrolysis.
