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.
