PrimeCoat® Z93x-series is a product range of water-based functional coatings purposely developed to improve corrosion resistance of galvanized steel. At different concentrations the products enable different applications, such as TOC (multifunctional permanent coatings), Passivation or primer replacement.

Additional properties where PrimeCoat Z93x products in exells are:

Reduction of the friction of the metal surface in forming operations
Improved bonding properties.

PrimeCoat® Z93x products contain acrylic resin and trivalent chromium. The products are free from hexavalent chromium Cr(VI) and fluorides. Galvanized steel sheet treated with PrimeCoat® Z93x is not sensitive for finger prints and is not easily removed by (alkaline) cleaning.

It is multi-metal: typical galvanized steel surfaces that will have advantage of the PrimeCoat Z93x coatings are: standard zinc, electrogalvanized zinc, Galvalume®, Galvannealed, magnesium-aluminium-zinc alloys, Alusi® and Galfan®.

Metal coated with PrimeCoat Z93x is combining excellent tribological properties and outdoor weathering resistance.

PrimeCoat® Z93x-series benefits

Trivalent chrome-based modular TOC product
Water-based chemistry and VOC (solvent-free)
TOC, Passivation and or primer replacement with one chemical technology
Low dry film coating weight
Excellent appearance, even at higher coating weights
Passivation properties, enabling excellent corrosion resistance even when no primer is used
Corrosion resistance surpassing Cr(VI) passivation
Good adhesion properties
Compatible with a range of paint systems; excellent paintability after PrimeCoat treatment
Easy application (chemcoater or spray/squeeze)
Excellent lubrication & mechanical properties to reduce galling in deep drawing operations (adjustable CoF)
Drying at low PMT (>40°C)
Key product parameters can be adapted to customer needs

Modular system Z93x series

A unique aspect of PrimeCoat® Z93x products is that they can be tailored to specific customer processes based on a modular system. By changing the product concentration or adding certain specialty additives specific product properties can be enhanced while maintaining good overall quality. If the application concentration is increased the product obtains TOC based characteristics, such as improved:

Corrosion resistance
Lubrication
Mechanical resistance
Adhesion properties
Anti-fingerprint properties

At a lower application concentration (<50%) it can be used as a high performing passivation. Convinced? Plan a test today!

Thin Organic Coatings (TOC’s)

Thin Organic Coatings (TOC’s), worden in een doorlopend proces aangebracht op thermisch verzinkt staal en andere metalen ondergronden. Ook brengen deze veel voordelen met zich mee, zoals het tegengaan van vingerafdrukken en het verbeteren, vormen en toevoegen van corrosie protectie.

PrimeCoat TOCs

Passiveren

‘Witroest’; de vijand van verzinkt (band)staal stalen strips is een vorm van corrosie die kan optreden tijdens opslag. Een zeer onwenselijke vorm van corrosie voor kritische toepassingen in witgoed, bouw en andere high-end industrieën.

Voorbehandelen

De duurzaamheid en levensduur van producten zijn eisen die consumenten als vanzelfsprekend beschouwen. Er wordt continu verbetering verwacht op dit gebied. Verf hechting en corrosie weerstand zijn factoren waar rekening mee moet worden gehouden bij de conditie van applicaties tot en met de laatste levensduur van een product.

Reinigers en speciale additieven

Olie, vet en andere vormen van oppervlakte verontreinigingen die ontstaan gedurende productie moeten worden verwijderd. Afhangend van de soort verontreiniging, kan dit worden bereikt door middel van het gebruik van zuur of alkaline gebaseerde reinigers.
