METAL PRE-TREATMENT

Degreasings

Pre-trattamento-metalli-glomax-min

The surface preparation is a critical step in the electrodeposition of any type of metal.
A surface completely free from oils, grease, oxides or other impurities before performing the electrochemical deposition is of fundamental importance since it avoids all the problems of adhesion of the coating on the substrate, pollution problems of galvanic bath by foreign substances and finally problems related to corrosion resistance.
During the surface preparation, two types of processes are used: degreasing and pickling, the first serves to eliminate oils, grease and dirt and is based on physico-chemical mechanisms while the second serves to remove oxides and is based on processes of chemical dissolution. Choosing the right steps and processes for each type of surface is not easy, but thanks to its gained experience GLOMAX can suggest different solutions after a careful study of the overall customer process.

  • CHEMICAL DEGREASING
  • PICKLING
  • ELECTROLYTIC DEGREASING
  • LIQUID DEGREASING

Glomax offers a wide range of chemical degreasings, called BEST SC, ideal for a good clean-up of any parts. Their choice depends on the type of substrate that has to be cleaned, for example the degreasing used for ferrous materials are very different from non-ferrous materials, for this reason we provide our BEST SC with more or less aggressive formulations that work in different operating conditions. Moreover chemical degrease can be integrated with specific additives called ALTAIR in order to improve their performance
