NanoCon : Chrom free conversion layer - NanoCraft Coating GmbH

NanoCon : Chrom free conversion layer
Cr-free conversion layer
NanoCon coating is based on the Smart
Coating Technology. It can be applied as an
ultra thin layer and generates a defined
intermediately conversion layer. The product
was developed together with industrial
partners and it fulfils high-class standards as
well as the demanded and necessary layer
parameters like chrome free.
basic, liquid water based and free of Chrom and other metals
generates conversion layers with good adhesion and corrosion
protection properties on aluminium and zinced steel surfaces.
the application takes place in the immersion as well as the spray
process fulfils all appropriate quality requirements.
free of Nanoparticles and heavy metal ions.
it corresponds to the directives the EU (directive 200/53/ the EC)
and the raw directive in 2002/95/. It is also ROHS conform.
Tested quality –
comparative high-class
investigations:
Acetic acid salt spray test to
ISO9227 DIN50021-ESS,
evaluated after 250h and
comparing chromate
conversion coating with
NanoCon.

Research and Development with modern Nanotechnology
We develop according to your demands especially functional
coatings for the highest surface claims. Or we provide you
by our proven Coating systems. We focus our developments
to stand the highest quality - verified by load tests, a
maximum process security, an optimized environmental
compatibility and a high economic efficiency. Furthermore
we optimise overall systems of customer-sided coating
process and integrate the newest technologies as for
example plasma pre-treatment for the cleaning and
activation of surfaces.

In principle, similar to the conventional products. Only small
process adjustments. (e.g. the extremely acidic pre treatment is
no longer necessary)
low in comparison to conventional products.
-The extremely acidic pre tretment is not necessary
