EonCoat is a spray applied industrial coating that prevents rust on carbon steel. EonCoat phosphates the steel it comes in contact with, forming an amorphous magnesium iron phosphate layer. This true alloy—chemically bonded to the steel—is the first line of defense against corrosion. Then, a white ceramic layer forms over the alloy layer. This ceramic layer, a second line of defense, provides a reservoir of phosphate corrosion protection to continuously maintain the alloy layer.
