Production method
ferrous sulfate oxidation method is used. Under stirring, enough 30% sodium hydroxide is added to the solution containing 150g/L ferrous sulfate to precipitate the 40% iron into Fe3 +(OH)3.
At the same time, Fe2 + to Fe3 + is oxidized by air at 30~35 ℃, and the pH value is reduced from 6 to 3.5 to form crystal nuclei.
Then add ferrous sulfate (14 times the crystal nucleus), adjust the pH value to 4 with sodium hydroxide, and then oxidize with air at 80°C, and then spray dry to obtain goethite iron oxide.
The above-mentioned iron oxide is placed in a converter, introduced into a hydrogen stream containing 20% water vapor, heated at 425-450°C, and then heated at 100-150°C in a nitrogen stream containing 10% air to obtain ferrous oxide 28% The iron oxide black pigment has a particle length and width of 0.7 μm and 0.5 μm, a specific surface area of 8 m2 /g, and a tinting force of up to 180%.
Micaceous iron oxide (MIO) paint is a two-pack polyamide cured epoxy primer/intermediate that has excellent water resistance due to the lamellar shape of MIO anti-corrosive pigment.

Whenever it is used for exteriors, it is necessary to be coated with polyurethane paints to avoid chalking.
For example, it is usual to apply a zinc-rich primer for storage tanks then apply an intermediate MIO epoxy coat and after that, a layer of polyurethane coating.
MIO - Micaceous Iron Oxide - is considered an anti-corrosive additive used in many kinds of paints and coating for over 100 years and is perhaps the most important barrier pigment used in coatings to protect structural steel. Its use is much more common in Europe than in the USA.
Micaceous Iron Oxide is regularly used to protect steel surfaces from the elements and corrosion and used on steel boat hulls, bridges etc.
The classic example is the Eiffel Tower in Paris.
Big Ben in London and the Sidney Harbor Bridge in Australia are other examples.
In the USA, MIO based coatings can be found on the Golden Gate Bridge and the San Francisco Bay Bridge.
Micaceous Iron Oxide is also used for durability and reliability on electrical and industrial equipment.
Micaceous Iron oxide (MIO) is a crystalline form of iron oxide that differs from Red, Yellow, and Brown variety of iron oxides.
Its crystals are very easily fractured into thin flakes & looks like mica.
This similarity gives rise to the term MICACEOUS and it is normally dark grey to black in colour.
All Micaceous Iron Oxide ores are generally occurred in Lamellar formation, along with Non Lamellar Hematite cavities.
Micaceous Iron Oxide is processed, Micaceous hematite ore with a metallic lustre or sparkle that can be easily seen with the naked eye.
Like the other forms of iron oxide, Micaceous Iron Oxide is a chemically inert material and is insoluble in water, organic solvents, and alkalis.
Micaceous Iron Oxide is un-reactive to most of the chemicals and is heat stable up to it's melting point of over 1,000 C (2,700 F).
Micaceous Iron Oxide is Non-Toxic, Non-Oxidizing, Non-Corrosive & Non-Flammable.
With such excellent chemical & environmental properties, it is not a surprise that it is the world’s most favoured barrier pigment for over 100 years.
Formulators consider Micaceous Iron Oxide to be a key weapon in their anti-corrosive arsenal.
Worldwide, Micaceous Iron Oxide barrier type pigment is used in performance coatings, primers, plastics and glass
Micaceous Iron Oxide barrier pigment is manufactured by us, catering to major paint companies in India and overseas which manufacture Protective Coatings.
Micaceous Iron Oxide has widespread use in protective coatings around the world because of its anti-corrosive properties, which stem from the unique nature of its flake-like particles.
When Micaceous Iron Oxide is incorporated into a coating system at an appropriate level, the flakes align parallel to the substrate surface, producing a shield or barrier of overlapping plates.
alignment enhances protection by providing barrier protection, ultraviolet (UV) light absorption, film reinforcement, and increased intercoat adhesion Micaceous Iron Oxide has widespread use in protective industrial and marine coatings.
Film Reinforcement & Adhesion Promotion
Use of Lamellar Micaceous Iron Oxide flakes in a coating toughen and strengthen the film.
Coatings formulated with Micaceous Iron Oxide can show greatly improved resistance to blistering and increased substrate adhesion.
For example, Micaceous Iron Oxide is used to promote adhesion in coatings formulated for galvanized steel, around the world because of its anti-corrosive properties, which stems from the unique nature of its flake-like particles.
When Micaceous Iron Oxide is incorporated into a coating at an appropriate level, the flakes align parallel to the substrate surface, producing a shield or barrier of overlapping plates.
This alignment enhances protection by providing harrier protection, ultraviolet (UV) light absorption, film reinforcement and increased intercoat adhesion
Increased Inter-Coat Adhesion
Micaceous Iron Oxide is compatible with almost all binders but more suitable for Epoxies, that form very hard surfaces and are difficult to recoat.
The incorporation of Micaceous Iron Oxide produces after weathering a surface with an excellent physical profile for subsequent coats.
Alternatively, coatings may be formulated with higher levels of Micaceous Iron Oxide to boost the intercoat adhesion of freshly applied systems.
Coating Performance
The quality of Micaceous Iron Oxide is only one of many factors that determine the performance of coating systems containing Micaceous Iron Oxide.
Being inert and neutral pH, are compatible with all of the major binder types.
They have been used successfully in phenolics, alkyds, urethane alkyds, epoxy-esters, chlorinated rubbers, styrene acrylics (acrylated rubber), vinyl co-polymers, polyvinyl butyral resins, vinyl chloride-vinyl isobutyl ether co-polymers, epoxy resins cured with polyamines or polyamides, moisture-cured polyurethanes and two-component polyurethanes.
In all cases, the protective nature of a binder will be enhanced by inclusion of an optimized level of Micaceous Iron Oxide.
Proper pigment loading and make-up are key to obtaining the benefits of Micaceous Iron Oxide.
Micaceous Iron Oxide has a much lower oil absorption than other lamellar pigments.
Formulations, therefore must contain much higher levels of Micaceous Iron Oxide than would be the case with, for example: Silica , Talc, or Mica.
The size of Micaceous Iron Oxide flakes 1.5 to 2 mils long and 5-10 micrometers (0.2 to 0.4 mils) thick dictates a DFT in excess of 50 micrometers (2 mils) to achieve a shield of overlapping flakes. For this reason, Micaceous Iron Oxide is normally found in high-build intermediate and finishing coats.
Pigment Quality
Natural Micaceous Iron Oxide is obtained from mineral deposits of specular hematite and there is tremendous variation in the physical and chemical properties of different sources and not all Micaceous Iron Oxide is suitable for protective coatings.
Two of the most important criteria are the amount of thin flakes and the chemical purity.
These properties, however vary widely from source to source and even within a single deposit.
In addition, the processing of the crude ore to remove impurities and control particle shape, size and size distribution is absolutely critical to final performance.
Micaceous Iron Oxide requires Micaceous Iron Oxide pigments to have a minimum thin flake content of 60%, with a further classification into two types.
Type 1 is of the highest quality with a thin flake content greater than 80%.
In addition, the standard sets maximum levels for impurities and a minimum level of iron oxide content.
Typical Applications of Micaceous Iron Oxide Based Coating
A typical system will consist of a primer containing corrosion-inhibiting pigments, one or two coats of Micaceous Iron Oxide intermediate, and, if a high gloss or bright color is required, a finishing coat based on a low chalking binder.
Micaceous Iron Oxide based coatings is proven technology for a coating system's durability is a proven track record on a similar structure exposed to a similar environment.
Micaceous Iron Oxide is a versatile pigment to make performance coating of Polyurethane, Epoxy, Acrylics, Polyesters, Alkyd, Chlorinated Rubber etc.
Micaceous iron oxide varnishes and micaceous iron oxide paints have a scaly structure.
Their pigments are also called "scale armour paint".
The paint covers the surface to be protected like a scale armour.
Corrosion is greatly reduced where his paint is used. Steel bridges, power poles, even the Berlin TV Tower and the Eiffel Tower are protected against all weathers with this paint.
