Pragokor Zn 62
two component-based agent for the preparation of chromating baths

Two component-based agent Pragokor Zn 62 is suitable for the preparation of chromating baths for the passivation of zinc coatings deposited from weak acid, alkaline non-cyanide and alkaline cyanide-based baths. The chromate layer deposited on zinc coatings, either dull or bright, is of olive green or grey colour, and may be further coloured with organic dyes for other tones. As for the finish, the chromate coatings resulted resemble to organic paints. Besides, they add to the overall corrosion durability substantially. The bath itself is convenient for both automatic as well as hand-operated plating lines.
