Zinc and zinc-alloy processes

Cyanide zinc SG-ZNC II-S

The SG-ZNC is a one component additive for all types of cyanide zinc processes with optimal brightness best throwing power, high temperature resistance and easy bath management. Very economical!

Acid zinc SG-ZNS-OT 2

SG-ZNS-OT 2 is a low-acidic, ammonium-free high-performance electrolyte for the generation of shiny and ductile zinc layers. SG-ZNS-OT 2 is a further development of our successful SG-ZNS bright zinc processes. Due to the high throwing power of the electrolyte and the above-average applicable current densities a considerably higher output of goods with shorter exposure times in drum and rack electrolytes can be achieved. Of course, any acid zinc process on the market can be switched to SG-ZNS-OT 2. Special features: Working temperature up to 50 ° C, ductile precipitation even with thicker layers, excellent brightness and throwing power combined with optimal metal distribution for rack and barrel processes. The process is made for air agitation and cathode moving processes and high economical through simple bath management since only 1 additive for normal work necessary is. The SG-ZNS OT 2 process can be operated on potassium and ammonium basis.

Acid zinc SG-ZNS-V 96

SG-ZNS-V 96 is used for low-acidic ammonium-free galvanizing. The brightener is a water-soluble brightener, which makes working up to 40 ° C possible. Of course, any commercially available acid zinc bath can be converted without any problems to SG-ZNS-V 96. Other special features are: In normal operation only 1 additive is required, high cloud point, ductile layers even with thicker deposits combined with an optimal metal distribution and high efficiency.

Alkaline cyanide free zinc SG-ZNA 100

The cyanide free, alkaline zinc bath SG-ZNA 100 is a further development of our ZNA 20 process and generates bright zinc layers on rack and drum applications on ground material of iron and steel. Layer thicknesses of up to 50 μm without pores and bubble formation are possible. The bath generates high-bright zinc coatings at current densities up to 8A/dm² and owns a very good brightness effect over the hole current density area combined with optimum metal distribution. It can also be used for highly profiled parts and also enables extreme hanging density. The working temperature up to 35 °C is possible. SG-ZNA 100 is a 3-component system with extremely stable additives! The produced zinc deposits are of high ductility an advantage especially for goods which are later bent, formed or welded.

Alkaline cyanide free zinc bath SG-ZNA 50N

The alkaline cyanide free zinc process SG-ZNA 50N deposits high bright zinc layers on rack and drum products made of iron and steel in layer thicknesses of up to 50 μ without pores and bubble formation. At current densities up to 6 A/dm² the bath produces shiny zinc coatings has a very good depth of brightness and metal distribution and can also be used for very strongly profiled parts. The working temperature is up to 35 °C. The generated zinc deposits are of high ductility which is particularly advantageous when the parts are later bent, molded or welded. SG-ZNA 50 N is a 4-component system with extremely stable additives.

Alkaline cyanide free zinc bath SG-ZNA 20

The cyanide free alkaline zinc process SG-ZNA 20 deposits on rack and drum produces on iron and steel shiny zinc deposits in layer thicknesses up to 50 microns without pores and blistering effects. At current densities up to 8 A/dm² the bath produces shiny zinc coatings and has a very good brightness depth and an optimal metal distribution over the entire current density range. It can also be used with very profiled parts and also allows extreme hanging density. The working temperature is up to 35 °C. The SG-ZNA 20 is a 2-component system therefore the bath management is very easy! The produced zinc precipitates are of high ductility an advantage especially for goods which are later bent, formed or welded.

Zinc - iron process SG-ZNA-FE 95

The cyanide free alkaline zinc-iron process SG-ZNA-Fe 95 generates bright deposits of zinc-iron alloy on rack and drum applications. The generated layers achieve when passivated a particularly good corrosion protection. At current densities of up to 6 A/dm² the process produces evenly bright coatings with very good brightness depth and excellent metal distribution. SG-ZNA-FE 95 can also be used on very profiled parts. The generated precipitates are of highly ductile an advantage especially for goods with later bending sharpening or welding. The layers can passivate very well and optimally in our passivation products.

Acid zinc-nickel SG-ZNS-NI 30

The SG-ZNA-Ni 30 deposits high bright zinc nickel alloy coatings with 12-15% nickel. SG-ZNS-Ni 30 shows a high current efficiency of >90% and can be operated without boric acid. SG-ZNS-Ni 30 is suitable for rack and barrel applications and has very good hiding power and throwing power. SG-ZNS-Ni 30 is suitable for direct coating of cast iron and hardened steel.

Alkaline zinc-nickel SG-ZNA-NI 100

Our alkaline zinc nickel SG-ZNA-Ni 100 produces zinc alloy coatings containing 12-16% nickel. The process is suitable for barrel and rack applications and produces uniform alloy layers over the entire current density range.
