ZINCAREV D2AEMono-component liquid degreasing acidThis compound benefits from new technology, which features an emulsion of oils, greases and organic residues.
These features enable:- a bath to retain the performance of a new bath- a bath to have exceptional lifetime
Acid degreasing
DESOX 555Solid alkaline degreaserIts deoxidizing properties make it a very powerful degreaser.It is highly effective on scaled parts (welds – heat treatments), thanks to its great descaling capacity.
ACTILID 4000 + PREMIX TASRTwo-component liquid degreaser providing great flexibility in degreasing adjustment and capacity.
ACTILID 7000Easy to use and reduced manipulation (1 component) for a powerful degreaser.
Alkaline degreasing
Pickling aims to remove
the scale and other oxides
present on steel surfaces.
This is done in a diluted
hydrochloric acid solution
at room temperature, with
the addition of an inhibitor
which prevents the steel
from being attacked when
cleaned of its oxides.

STEAMER 700Anti-vapour additiveProvides very significant reduction of hydrochloric gas emissions from pickling baths. This additive modifies the air/liquid interfacial tensions, preventing or reducing the evaporation of hydrochloric gases from the bath surface. This additive is fully compatible with all the other products used in the surface preparation line.
ZINCAREV MAD 16Degreasing additiveEnables degreasing directly in a pickling bath. This function can be needed when the galvanizing unit does not include degreasing, or when, for a special operation, the degreasing capacity of the surface preparation line has to be strengthened.

There are three main reasons for using corrosion inhibitors in hydrochloric pickling baths :
1 - To make cost savings on pickling or stripping baths by reducing the attack of
the bright metal. The inhibited acid only attacks the iron oxides present on the parts,
and not the metal. It is pointless to contaminate baths with the client’s metal, given that
galvanization is afterwards sold by weight.
2 - To limit as much as possible the embrittlement of parts through hydrogen
occlusion. For safety reasons and to avoid the breaking of parts under mechanical stress.

POLYTENSID 55Surfactant - PassivationFor lowering the surface tension of fluxing baths.This function improves chemical exchanges,including the fluxing quality and greatly reduces product consumption and the loss of surplus salts, including the formation of hard zinc and ashes in the zinc bath.

TECHMOUSSE IIIAnti-foamerStops the formation of foam in stripping baths.
DESOXACID 5151Acid renovator for oxidized galvanized parts
The special products in this range were developed at the request of galvanisers who explained certain problems often encountered in the business.
EPUROILDemulsifierAdded at 0.5% concentration to heavily contaminated baths, EPUROIL “salts out” greasy organic matter. This is a technical solution for treating oils and greases, which prevents them from disturbing the treatment line.

Passivations
HEXACRYL 500Organic passivation
PASSIVATION VCDMineral passivation trivalent chrome
ACRYL 2000Organic-mineral passivationPassivation ACRYL 2000 (Organo-Mineral Passivation) has the same characteristics as organic passivation with greater protection in corrosion resistance (up to 8 months oceanfront exposure without loss of brightness), parts passivated with ACRYL 2000 can be painted without any special preparation.
- allow outdoor storage without alteration of the gloss for 3 to 8 months
THE PASSIVATIONS :
- facilitate the transport of parts by sea and / or truck without the risk of white rust during transport
- prevent the mix of brilliant piece and dull piece during assembly of the parts on site
- improve the strength of the parts during storage in difficult conditions at construction sites (moisture, mud, ...)
ECO PASS SPMineral passivation for application by spray gun
COLOR PASS Colored passivations
All passivations VCD are free of hexavalent chromium and products which are carcinogenic, mutagenic or toxic for reproduction (CMR).
