E-Brite 30/30 is an alkaline non-cyanide process that plates directly on steel, copper, brass, stainless steel, zincated aluminum, electroless nickel and most high quality properly prepared zinc diecastings in both rack and barrel installations. Lead alloys can be plated in rack lines. It is free of chelating agents.

The next generation was alkaline non-cyanide zinc plating solutions including alkaline zinc-nickel, followed by acid zinc chloride processes developed by Max Schloetter. The acid chloride formulations allowed the use of alloying metals such as zinc-cobalt, zinc-iron, zinc-manganese, zinc-nickel, and zinc-tin

Alkaline non-cyanide process. E-Brite 30/30 is an easy-to-use, one-tank process that eliminates the need for cyanide or pyrophosphates. Optimal adhesion allows for plating directly onto a variety of metals. Uniform low current density distribution with greater throwing power than cyanide copper. Produces a non-porous, fine-grained, smooth, and ...

Jan 11, 2013· The usual approach to copper plating on steel is to strike with copper cyanide, copper alkaline non-cyanide, or nickel first -- and then to do the bulk of the copper plating with acid copper plating. But Berl says this thickness isn't a problem for a proprietary alkaline non-cyanide plating bath, and Berl invariably only says something can be ...

Non-cyanide alkaline bath was used to prepare copper thin films. Influences of various temperatures on deposition rates, surface morphologies and microstructures of films were investigated.

A process for electroplating copper from an aqueous alkaline non-cyanide bath has improved resistance to degradation. At least a portion of the plating bath is subjected to electrolysis by an insoluble anode to which the current is controlled independently from the current to the soluble copper anode in order to reduce the level of bath impurities and maintain the quality of the deposit.

A cyanide-free alkaline bath containing sodium potassium tartarate (SPT), and triethanolamine (TEA) has been developed by Hull cell studies to electroplate copper. A trace amount of potassium thiocyanate (KCNS) in the bath solution improved the quality of the copper deposit and also improved the efficiency of the plating process.
