Alkaline Zinc Plating

Alkaline zinc plating is the process of electroplating with alkaline solutions. Alkaline zinc plating has excellent low current density covering and throwing power and is especially good for rack plating parts with deep recesses.

COLZINC ACF-II PROCESS FOR ALKALINE CYANIDE-FREE ZINC PLATING

Description

COLZINC ACF-II is a concentrated, multiple polyamine blend that produces a brilliantly bright deposit from alkaline cyanide-free plating solutions.

COLZINC ACF-II operates over a wide zinc metal range of 0.75 – 3.5 opg (5.5 – 26.0 g/l).

COLZINC ACF-II produces extremely ductile deposits even with thickness in excess of 1.25 mil. (31.75 microns).

COLZINC ACF-II is a high temperature process capable of plating bright, decorative work at temperatures of 125°F+ (52°C+).

COLZINC ACF-II has excellent low current density covering and throwing power, and is especially good for rack plating parts with deep recesses such as fittings, tubes or computer chassis.

COLZINC ACF-II is extremely tolerant to trace contaminants such as calcium, magnesium, lead, cadmium, iron and chromium, which enter the plating bath via maintenance additions of caustic soda, tap water, zinc metal replenishment and drag-in from the pre-plate processes.

COLZINC ACF-II is ideal for both low current density barrel plating and the wide range of current densities encountered with rack plating.

COLZINC ACF-II deposits readily accept conventional chromate post plate treatments normally used in bright zinc plating.
