Science & Technology of EonCoat


EonCoat’s science & technology has a fundamentally different approach. Traditional industrial coatings only delay the onset of corrosion. EonCoat’s patented formula goes a step further by chemically bonding to steel. Unlike polymer coatings, EonCoat prevents corrosive elements from penetrating the alloy layer. This inorganic steel coating contains no carbon molecules and is a chemically bonded phosphate ceramic. EonCoat is exothermic and forms at room temperature.

Phosphate Ceramic Steel Coating

EonCoat takes a user-friendly and highly effective approach to protect steel from corrosion. This phosphate ceramic steel coating is easy to apply. Simply spray EonCoat through any standard industrial plural pump system. Two components, an acid, and a base combine before contact with carbon steel.  

Upon contact with EonCoat, the surface of the steel forms an alloyed layer of amorphous iron magnesium phosphate. This true alloy layer, about 5 microns thick, serves as the first line of defense in preventing the steel from corroding. On top of the passive alloy, a white ceramic layer forms. This layer, much thicker than the alloy layer, is measured at 20-30 mils. This layer serves as a phosphate reservoir, allowing the steel to self-cure by maintaining the alloy that is chemically bonded to the steel. 

The inorganic steel coating technology behind EonCoat just makes sense. A phosphate ceramic steel coating that prevents corrosive materials from ever reaching the steel is the ultimate way to protect it. Even NASA agrees. Click here to learn more about NASA’s evaluation of EonCoat.

EonCoat Layers


Iron Phosphate Layer

This is the first line of defense EonCoat delivers. When this alloy layer is viewed through an electron microscope, it shows a thickness of about 5 microns. Clearly visible in the electron microscopy is the chemical bond that results from the steel coming into contact with the patented acid formula in EonCoat. The resulting alloy is a permanent protective layer against corrosion.

Ceramic Layer

The second layer of protection delivered by EonCoat is a 20-30 mil thick ceramic shield that serves as a phosphate reservoir to continuously re-phosphate the steel in the event that the alloy layer is damaged. This ceramic layer is chemically bonded to the iron phosphate alloy layer. The ceramic is very hard and provides strong abrasion resistance and high impact resistance.

Chemical Charge Eliminates Gaps & Phosphates Steel

Due to its chemical charge, EonCoat is actually pulled down into the valleys of the substrate profile. Unlike traditional coatings that sit atop the profile with coverage gaps in the valleys where corrosion begins, EonCoat covers the entire substrate. There are no gaps. An amorphous alloy layer of iron phosphate forms. This contiguous phosphate layer is created through a chemical reaction with the steel the EonCoat and the steel share ions and the EonCoat chemically becomes part of the steel. There are no coverage gaps. And there is no way for corrosion to get ‘underneath’ this stable covalent bond. The molecular bonds form through the sharing of electron pairs between the atoms in EonCoat and the atoms in the steel.

The Alloyed Steel Will Not Corrode

Traditional barrier coatings fail because they sit like a tarp over the steel, and once the tarp is torn and moisture enters, the steel corrodes. By definition, barrier coatings always fail, because once a barrier coating is compromised corrosion spreads like cancer.

EonCoat is NOT a barrier coating.

EonCoat is self-healing. First, the coating forms a magnesium iron phosphate alloy layer with the steel. Then a ceramic topcoat forms over the alloy layer. The ceramic functions as a phosphate reservoir to continuously protect the alloy. If the ceramic is scratched or chipped it has no effect on the corrosion protection of the alloy. So the steel is still protected. And even if someone cuts a scribe line through the ceramic and through the magnesium iron phosphate alloy, the ceramic layer will leech phosphate to re-alloy the steel.

No barrier coating in the world provides this self-healing ability to re-alloy steel.

Watch this video to see how well protected the steel is against corrosion with just the iron phosphate layer after coating.
