Chemically Bonded Phosphate Ceramic (CBPC) Coating – EonCoat- outperforms traditional products in terms of preventing corrosion. This inorganic coating utilizes inorganic components (ceramics) to achieve long-term durability due to inorganics’ stable and robust nature. This coating is ceramic, meaning it is comprised mainly of quartz instead of plastics. Quartz is composed of silicone dioxide, which is immune to environmental decay, as there is no breakdown mechanism in inorganics which leads to decay from aging.
Corrosion is the greatest consumer of metals known to man. It costs society billions of dollars annually. It is wasteful of natural resources and causes considerable inconvenience to human beings and sometimes loss of life. The use of protective coating with or without cathodic protection is the most widely used form of corrosion protection. Traditional coating protection involves applying a barrier comprised of layers of Epoxy or Polyurethane to the substrate. These barriers require constant maintenance to prevent failure from even minor damage or excessive wear to avoid exposure to moisture, which is when rust begins.
A method of preventing carbon steel from corroding is to alloy the surface of the steel with an amorphous phosphate protective layer. Specifically discussed is a novel spray-applied coating developed using inorganic acid-base chemistry to create and grow a passive layer on the substrate.
Most traditional technologies focus on temporarily addressing the symptoms, not the core problem. This technology aims to directly solve the root cause, providing complete protection for carbon steel from corrosion. Instead of a temporary barrier coating, it alloys the steel and prevents rust from ever developing. Unlike traditional polymer coatings, this Phosphate Ceramic coating chemically bonds (reacts) with the steel substrate molecules. This chemical reaction causes the coating’s molecules to become a part of the molecular chain of the substrate. Through the reaction between steel and the coating, a thin iron phosphate layer is formed. This would be the first line of defense against corrosion. Then, a chemically bonded phosphate ceramic layer rapidly forms on top of the iron phosphate layer. This ceramic layer functions as a second line of defense. This topcoat continually leaches phosphate to prevent rust from ever forming. In this process, the coating becomes integrated into the surface’s molecular structure and part of the steel.
