EonCoat CUI / High Temperature Coating

The High-Temperature Permanent Corrosion Protection Coating 

EonCoat CUI / High-Temperature Coatings works by alloying the surface of the carbon steel with an especially high-temperature iron phosphate layer. The white ceramic layer which forms on top is also highly temperature-resistant at up to 450C and is filled with phosphate. This chemically bonded phosphate ceramic will prevent your substrate from ever getting corrosion and permanently Protect your steel asset.

This coating can be applied in most atmospheric conditions. Salt and humidity do not interfere with the EonCoat bond to carbon steel. Much like EonCoat Corrosion Protection Coating, it is a 2 part system.
