Lustra-Zinc AC 440 is said to be a concentrated liquid brightener for producing bright, adherent deposits from mixed chloride zinc plating baths.  Brightener is designed to produce exceptional low current density brightness, particularly in high-volume barrel plating applications and rack lines. Low-foaming formula is compatible with air or mechanical agitation and evaporative recovery systems. The product is said to readily-plate iron castings, heat-treated steel and carbonitrided steel. It’s highly soluble and will operate at high temperatures. Deposits are designed to readily accept chromate post-treatments, including blue-bright, yellow, olive drab and black.
