E-Brite 23-11 Cyanide Copper Plating

E-Brite 23-11 is a unique leveling bright cyanide copper plating process.

EPI’s first products were cyanide based processes for plating copper and brass for the plumbing, lighting fixture and builders’ hardware manufacturers. E-Brite 23-11 was the first single inorganic maintenance brightener additive for cyanide copper plating in 1954. This product has been continually improved over the years and now is the best performing cyanide copper process available worldwide. Being inorganic, overdosing the brightener does not cause blistering, peeling, pitting or any other plating problem. The inorganic brightener does not decompose and no breakdown products are produced. It is relatively unaffected by the presence of organics or metallic contaminants that affect other brighteners.

The unique E-Brite 23-11 plates bright from 1 amp to 120 amps per square foot because it is an air agitated bath. It is a high speed bath that plates brighter over a wider current density range than any other cyanide copper process. It can be plated at much higher current density and hence higher plating speeds, resulting in greater thickness in less time. This very important characteristic of the E-Brite 23-11 process is advantageous when minimum thickness specifications must be met in the low current density area because the current can be increased to plate faster in the low current density area without burning in the high current density range.

The build up of carbonates from the air is not a problem because the process uses Electrosolv, a truly unique additive that not only retards the formulation of carbonates, it is twice as effective as Rochelle Salts. It also functions as a very effective anode corroder replenishing the metal in the bath producing a more economical plate. Greater plating thickness can be obtained in less time with the greater efficiency of Electrosolv. It will greatly improve the performance of any cyanide copper bath and is consumed only by drag-out. It contains no chealators.

The E-Brite 23-11 is a real money saver in nickel plating processes because of its bright and level underlying copper plate, which reduces the amount of nickel plate required. This is true with steel and zinc die castings.
