Hybrid Nano-composite coatings are a high toughness, durable Nano-composite coating that is molecularly bonded to the surface of steel. The coating combines the properties and reliability of extremely tough, durable, and corrosion resistant engineering thermoplastics, with the abrasion resistance and durability of glass-ceramics. Using proprietary chemistries, this hybrid Nano-composite is applied and molecularly bonded to the surface of steel, forming a permanent, durable, abrasion and corrosion resistant coating.
