The new surface applications on Zinc-Copper-Titanium rolled
sections is based upon this technological breakthrough and the
development of three diverse outputs. In all cases the results are
surfaces with chemical and physical features which are unique and
Surface treated ZINTEK is a phosphate coated Zinc-Copper-Titanium
alloy processed by a cationic crystalline product, in full
compliance with international normative UNI ISO 9717, with a final
"environmental" complex Zirconium salt oxidation stage.
Specifications and features:
· Weight of coating 3 ÷ 4 g/m2
· High level of atmospheric corrosion resistance tested through a
series of comparative trials of exposure to salt spray testing in
compliance with norm ASTM B117.
· A solid crystalline layer as evidenced by tests made with a SEM
The chemistry of the surface
In general a surface conversion process and phosphate coating
in particular, induce crystalline growth on a metal surface.
Unlike any other type of application such as galvanized coatings
the formed layer becomes an integral part of the surface itself.
Considered altogether the conversion process that takes place on
the surface is nothing less than extraordinary.
Mechanical resistance properties
Mechanical resistance and adhesion tests have confirmed
excellent adhesion and durability properties. Tests were conducted
in compliance with norm DIN EN ISO 2409 (crosscut test), the ECCA
- T 7 test (T-bend test) and the ECCA - T 6 trial (deep drawing
Continuous and rigorous lab tests keep corrosion resistance
properties in constant check for all products derived from the
Resistance trials to atmospheric oxidation due to the cationic
phosphate coating followed by the oxidation stage, are performed
through salt spray testing in compliance with norm ASTM B 117.
