“SDM Zincate”

A Process for Plating Aluminium

Aluminium forms an oxide the moment it is exposed to the air. This presents a problem when plating it, as the oxide prevents the plate from sticking. By using the Zincate process as a pre-plate dip, we chemically remove the oxide layer and at the same time, apply a layer of zinc. The zinc protects the aluminium until it is ready to be plated. As the part is lowered into the nickel tank, the zinc is etched away by the nickel solution and plating proceeds onto a clinically clean surface.

The part is rinsed and prepared for plating in our CASWELL Regular Nickel, Copper or Copy Chrome kits or in the Electroless Kits of Nickel or Copy Chrome.

(makes 4 litres of Zincate solution)
