Zinc baths are a coating of a metal substrate by a shiny layer of zinc electrolytically deposited in a bath with alkaline electrolytes free of cyanide, boric acid and ammonium in order to protect the piece from aggressive agents.
We can apply supplementary finishes over this coating:

Boric Acid and Ammonium free

Bright and leveled deposits

Excellent bright throwing-power

Low bath temperature

Biodegradable surfactants agents

Deposition on simple Steel, alloyed Steel and Cast Iron

It reduces the drag-out waste of the zinc plating bath, allowing for a recovery reintegration
