CHEMOPUR SANCY alkaline cyanide-free zinc

CHEMOPUR SANCY 2001

CHEMOPUR SANCY 2001 is a highly efficient liquid brightener system for shiny zinc deposits from a cyanide-free alkaline zinc electrolyte based on potassium or sodium.

CHEMOPUR SANCY 2001 additives cause a strong polarisation in the high current density range leading to a preferred zinc deposition in the lower current densities.

It is characterized by an excellent throwing power and almost ideal metal distribution and produces stressless ductile zinc layers in barrel and rack operation with excellent chromatability.

The amount of chelating stabilizers in the bath is extremely low and does not cause trouble in wastewater treatment thus keeping wastewater treatment costs very low. CHEMOPUR SANCY 2001 deposits zinc layers under compressive stress and show fine crystalline structure being columnar at rack operation.

The brightness range depends on operation parameters. Depending on dosage of the additives the layers show satin-gloss or high brightness and are well deformable due to their compressive stress.

The corrosion behaviour is very good because of the low inclusion rate of organic compounds and exceptionally good metal distribution.

Special advantages of CHEMOPUR SANCY 2001

  • Low bath parameters thus low wastewater pollution
  • No glitter formation, no blistering
  • High efficiency up to approx. 80 %, very high deposition rate
  • Exceptionally advantageous metal distribution up to almost 1 : 1,
  • Even at high coating thickness no blistering of glitter formation
  • No edge-growth
  • Simple bath management
  • Operation temperatures of 20°C to over 40°C possible

CHEMOPUR SANCY 2001 Glanzträger und CHEMOPUR SANCY 2001 Glanzzusatz can be delivered as triple concentrates as well.

CHEMOPUR SANCY 2017

CHEMOPUR SANCY 2017 is an alkaline zinc process for the deposition of satin-glossy to bright ductile layers. By the use of modern additives an exceptionally good metal distribution can be obtained (almost 1:1).

CHEMOPUR SANCY 2017 can be operated potassium-based or sodium-based and

Is suitable very well in both rack and barrel operation.
