Degreasing

Thorough cleaning of the surface to optimize the following stages and to guarantee a perfect finish. Of two types: ACID or ALKALINE. Each option offers specific benefits that have to be taken as an advantage in each installation. The specific products we offer for the degreasing process are:

  • BD Galvanet: Acid degreasingagent
  • Cleaner Forte 372: Strong alkaline degreasing agent
  • Cleaner CC15: Inhibited alkaline degreasing agent
  • Detergent 45: Foam control additive
  • Detergent 56: Foam control additive. 

Pickling

Steel is pickled to remove impurities, rust, and swarf. However, during this stage, the bare iron is also targeted.

The inhibitor protects the clean metal during the treatment in the pickling bath with hydrochloric and/or sulphuric acid. There is less iron dissolved in the acid, which reduces the acid use and prevents hydrogen fragility. Below you have a list of the solutions we can offer you for the pickling process: 

Raw Materials:

Hydrochloric Acid

Sulphuric acid

Phosphoric Acid

Specialties:

Degreasing activator for the pickling. By applying our Additive SP in your bath, you will get an acid bath. You will get a lighter pickling that will degrease your metal parts at the same time.

Our Inhibitor 04 is a highly effective corrosion inhibitor.

Flux

The purpose of the Flux process is to activate the surface of the steel to ensure that the hot zinc is properly deposited and to prevent the formation of unwanted layers of rust that could lead to the incorrect adhesion of the zinc to the metal base. The products we offer for these process include:

  • Zinc chloride
  • Ammonium Chloride
  • Oxygenated water
  • Ammonia

Passivation

Passivation is a conversion chemical treatment for recently galvanized steel surfaces. It creates a transparent or barely-visible layer that provides enhanced corrosion resistance to galvanized steel surfaces.

Our products are free of hexavalent chromium.

Enables direct passivation, which means it can be used without prior cooling or rinsing. This product does not contain Chromium VI.

Quality

Certifications that guarantee that we comply with the highest quality standards in terms of products, services and management.
