Zinc & Zinc Alloys

Zinc and Zinc alloys provide high performance cost effective coatings which together with trivalent chromium based passivates and organic top coats provide excellent corrosion resistance to steel based components. These coatings are protected by a mechanism of sacrificial protection. The zinc/ zinc alloy coating corroding preferentially to the substrate.

The initial attack on the zinc/ zinc alloy coating is inhibited by the passivate/ organic top coat layers which inhibits the formation of white rust. This multi-layer approach provides excellent corrosion performance and has many automotive companies approvals. All of these systems are covered by the MacDermid Enthone Zinklad Automotive Corrosion programme.

Kenlevel Ultima Acid Chloride zinc process:

Kenlevel Ultima represents the latest development in acid chloride zinc plating. The process is formulated for both rack and barrel applications over a wide temperature range with high temperature tolerance. Kenlevel Ultima produces excellent deposit brightness and levelling. The single brightener system is chlorine free and low foaming.

Kenlevel 019LF Chloride zinc plating process:

Kenlevel 019 LF is a low organic zinc plating process designed to work in either rack or barrel applications. It may be used in potassium, mixed or ammonium-based electrolytes. Kenlevel 019LF is a two-component low foaming system that permits higher air agitation resulting in brighter deposits. The process is easy to control and is free of complexing agents.

UNIZIN B830 Bright Cyanide zinc process:

UNIZIN B830 Bright cyanide zinc is a unique plating process that incorporates state of the art additives. These additives function in low, medium and high cyanide electrolytes. The bath produces an extremely bright, working at high temperatures, fine grained deposit that readily accepts Iridite and Tripass conversion coatings.

ZINCROLYTE KCL-NI IV

 ZINCROLYTE KCL-NI IV is a high performance mildly acidic zinc -alloy process to plate bright zinc-nickel alloy layers with a nickel content of10 to 16%

The process is especially suited for the plating of cast iron parts like brake callipers for the automotive industry due to very good plating initiation and adhesion on the substrate.

 ZINCROLYTE KCL-NI IV features:

• Very good corrosion resistance – meets the needs of many corrosion specifications.
• High process efficiency
• High hardness and good abrasion resistance.
• Good coverage and uniform nickel distribution, over a full current density range.
• Contains mild complexing agents and is free of ammonia.
