DEUTEQ CUBRITE **0
Bright acid copper process

Introduction

1.    Deposits a brilliant ductile copper with excellent leveling. High brightness and excellent leveling are obtained over the whole current density range.

2.    Used as an undercoat for a variety of nickel-chromium combinations on steel, brass, aluminum, zinc die castings and plastics.

3.    Brightener additives are very stable resulting in high quality production at low brightener consumption.

4.    The adhesion between copper deposits and nickel deposits is excellent. In addition, the copper deposits are soft, very ductile and have a low internal stress which is ideal for plating on plastics.
