Pretreatment

Prerequisite   for an excellent quality and good adhesion metal deposition is to follow the necessary stages of pretreatment, using the appropriate chemical products.

Our company provides you with the right chemical products and equipment :

(Ultrasonic Equipment, Tanks, Electrical Heaters, Rectifiers, Heat Exchangers (Serpentines) etc)

Ultrasonic Degreasers

These are alkaline  soaps (mainly in liquid form), used  in Ultrasonic Machines, and are appropriate for removing the   polishing pastes, oils etc from articles made of Gold, Silver, Steel, Aluminium, German Silver (Alpaka), Zinc die Cast.

They should be diluted in water to form aqueous solutions of 2-3 %. Working Temperature : 60-80 degrees Celsius.

Soak Cleaners

These are alkaline soaps, which are diluted with water (5%) and at working Temperature 60-70 degrees Celsius remove polishing pastes, oils etc.  from items made of Gold, Silver, Brass, Copper,  Steel, Aluminum, Zinc die Casting.

Our company  can provide you with Tanks  and Electrical Heaters.

 

Pickling

  • Additives, which  are mixtures of inorganic and organic acids, appropriate surface-actives substances  and inhibitors, and  remove the surface oxidation from articles made of Copper, Brass, Steel, Aluminium alloys, Stainless steel etc
  • Degreasing Additives : added in small amounts in acid pickling solutions (usually based on  Hydrochloric Acid)and  help the degreasing of the articles.
  • High Efficiency  Inhibitors : added in acid pickling solutions and protect the metals from etching.
  • Suppressing Acid Fumes Additives: added in acid pickling solutions with Hydrochloric Acid and reduce the escape o Hydrochloric Acid vapours into the atmosphere.

Electrolytic Degreasing

This electrolytic step is applied before electroplating and is precondition for an excellent quality and good adhesion of metal deposition.

The substrate determines if cathodic or anodic degreasing should be applied.

“Degreaser – Copper Plating’’ (red) is also avaliable.

Our company can provide you with appropriate Tanks  and Electrical Heaters.

 

Activation

Chemical products appropriate for the activation of articles made of Silver, Brass  etc before the immersion plating or electroplating.
