A non-cyanide alkaline zinc process distinguished for giving highly ductile deposits, without flaking and blistering even if larger thickness of deposit is involved. Suitable both for rack and barrel applications without the need to drastically adjust the basic composition. An optional additive dedicated for special cases enables obtaining deposits of thickness greater than 15-20 microns while maintaining their ductility.

This technology guarantees low operating costs while maintaining exceptional brightness. It enables operation at high electrolyte temperatures (up to 35ºC) - current density can be increased, excellent throwing power achieved and costs of electrolyte cooling reduced.

Advantages:

• greater production efficiency and reduced electrolyte costs - shorter application time and decreased total thickness of the zinc deposit necessary to cover hard-to-reach places
• flaking eliminated even when plated components are having thicker deposits
• plating of complex shapes at both high and low current density
• excellent ductility and uniform distribution in a wide range of current density
• free of binding and chelating agents
• easy waste-water treatment

The process is widely recognized in the global galvanic market, primarily due to the esthetic effect, durability of the coatings obtained and reduced bath operation costs.

This process is dedicated for use at high-temperatures (up to 45°C) installations. Produces bright ductile deposits over wide current density range and can be used for both rack and barrel applications.

Advantages::

• this technology produces a unique, stable solution with unsurpassed solubility that eliminates problems with oiling-out even at high temperatures
• produces ideal zinc deposit easy to undergo chromating process, as a result the chromate coating is uniform in terms of both thickness and colour – excellent passivation adhesion
• readily plates over malleable iron, castings, heat-treated steels
• plating of complex shapes at both high and low current density and both in rack and barrel installations
• the process ensures excellent brightness at low current density and hence proves to be an ideal process for barrel plating

A passivation process that produces light blue chromate coatings. It does not contain chromium VI, and yet it produces coatings with two to three times better corrosion resistance compared to classic hexavalent chromating process. The thickness of the chromate coating depends on the concentration of the passivation concentrate in the working solution. It can be used for passivation of zinc coatings obtained from alkaline and low acidic electrolytes, in both rack and barrel installations.

Advantages:

• the produced chromate coating is highly temperature resistant and withstands 48 hours at 120°C without influence on colour and corrosion resistance
• passivated parts withstand 80-100 hours in a salt chamber with white corrosion of not more than 5% of the reference surface
• at concentration of 155 ml \l, conversion coatings with thickness over 300 nanometers and excellent corrosion resistance are obtained
• the process is less aggressive to zinc deposits as compared to passivation based on chromium VI, which extends the longevity of working solutions
