Columbia Chemical Named Approved Boeing Supplier for Cadmium Brightener Applications

Columbia Chemical Corp. has been granted approval by the Boeing Company as a supplier of cadmium brightener for applications on all models of their commercial airplanes. Columbia Chemical’s COLCAD 100 brightener for cadmium plating is designed to produce brilliant, uniform deposits in both rack and barrel plating applications while providing long operating life with low-cost bath operations.

Tom Alderson, sales manager Americas for Columbia Chemical, one of the world’s largest manufacturers of zinc and zinc-alloy plating additives, worked closely with Boeing representatives to gain the approval. “Boeing faced a serious problem because manufacturers of previously approved products decided to discontinue them,” he said. “Because the former products are no longer commercially available, Columbia Chemical’s COLCAD 100 is now the only Boeing-approved cadmium brightener available for these applications.

The approval also allows platers to add COLCAD 100 to existing baths containing former Boeing-approved cadmium brightener.
