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.

Typical Characteristics
   

Standards

IRONOR ^® fits to the following standards :

• ISO 10601 classe I
• Deutsche Bundesbahn TL 918 300
• ASTM D-5532 Type I
• EN 71/3 (Food contact)

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.

IRONOR® barrier effect

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.

Applications of IRONOR ^® paints

Drilling rigs Electricity transmission towers Off-shore platforms, facilities and containers Pipelines Refineries Road and railway bridges Storage tanks Transformers Water and wastewater facilities
