 IRONOR®
IRONOR® is a natural Micaceous Iron Oxide (MIO). Its excellent platelet
structure and high chemical resistance make it an ideal pigment in many
anticorrosion paint formulations. IRONOR® paints provide longlife corrosion
protection for metallic structures in touch with very aggressive environments,
such as marine and industrial ones.

Performances of IRONOR
®
Barrier
effect
When an IRONOR®
based paint is applied to a surface, the flaky
pigment particles orientate themselves in multiple layers roughly parallel to
the substrate in such a way that interleaving and overlapping take place.
This barrier effect will reduce the diffusion of moisture and polluants such as NaCl and SO2
through the medium, thus decreasing the chances of corrosion and
blistering.

UV
shielding effect
IRONOR® particles are impervious to UV radiation and
therefore protect organic binders from early degradation by light and UV
rays. This is due to the coherent barrier and to the drastic IRONOR® absorption in the ultraviolet
region.
Film
reinforcement
Paint film reinforcement, which reduces film distortion, is due to
the high aspect ratio of IRONOR® and
its preferable orientation parallel to the substrate. Consequently the film
shows high mechanical properties and an improved cracking resistance.
Adhesion improvement
On galvanized surface, it has been shown that IRONOR® enhances
the adhesion of paint layers. Even allows one coat system to be efficient
principally for high-voltage transmission towers. Moreover this pigment helps
to obtain better recoatability, especially for
epoxy coatings and thus reduces expensive and not very compliant surface
treatment.
Thermal expansion
Major content of IRONOR®
is Fe2O3, which has a similar coefficient of thermal
expansion to the metal substrate and consequently reduces flexing and
cracking of the paint applied to the metal substrate.
Low soluble salts content
Soluble salts can form electrolytes in the paint system, and forming
galvanic cells leads to film breakdown. IRONOR® is extracted in deposits, which
have a particularly low soluble salts content.
Moreover its airclassification process removes most
of the amorphous superfine particles, which lead to high soluble salt levels.
SEM analysis of IRONOR® shows the surface to be clean of superfine
particles.
Food
contact
Since IRONOR® is free of toxic
ingredients, it is extremely useful for nonpoisonous finishes applied to food processing plants
such as sugar refineries, dairy plants, breweries and distilleries.
Coloration
IRONOR® is grey with
metallic sheen and is easily mixed with a large range range
of pigments to obtain interesting dark shades (brown, red, grey…). TiO2
can be added to lighten the shade. Once again, by removing most of the
amorphous super-fine particles, which are natural red oxide, air
classification techniques help to ensure greater batch color
control and consistency in batch-to-batch coloration.
