EMULSION POLYMERS WHICH PROVIDE SCRUB RESISTANCE AND BLOCKING RESISTANCE IN HIGH AND LOW PVC PAINT FORMULATIONS

摘要

An electrode 1 having an active surface for contacting an electrolyte. The electrode 1 comprises first and second metallic materials 2,3 arranged to provide a number of first metallic material to second metallic material interfaces at the active surface. The invention also relates to a method of making such an electrode 1 and to an electrolysis cell provided with such an electrode 1. The first metallic substrate, corresponding to a substrate of the electrode, may be steel. The second metallic material may be nickel or a matrix of nickel and chromium. The electrode is produced by plating a substrate of a first metallic material with a second metallic material and removing regions of the plated second metallic material, eg by machining. The surface of the substrate onto which the second metallic material is plated may be made uneven, eg by etching, to create raised portions and trough portions onto which the second metallic material is plated.
