Steel guard nanocoat™”, is an inorganic, water based anti-rust compound. It conforms to the rohs directive and is non- evaporative, non-inflammable liquid. “steel guard nanocoat™” is a unique, ready to use, water based rust preventing compound. It prevents rust & corrosion by acting at a molecular level of the steel surface and completely restores it to rust-free condition. In addition, “steel guard nanocoat™” also increases the bonding strength to the applied material between 100% - 300%, thus giving it an extended strength & life in construction. It is based on nano-technology, wherein one thin layer of ‘0. 2’ (zero) microns acts at a molecular level stopping the formation of fe2 & fe3 ions (i. E. Rust). It penetrates into the surface of steel forming dense micro crystals (d. M. C. ) between the molecules of iron within the surface and not above it, retaining the original properties of the steel. Steel guard nanocoat™” is water based rust preventer which makes the applied surface rust & corrosion free. It has a much superior performance and provides much greater life & durability to the metal over other solvent based primers even in high salt based corrosive conditions. “steel guard nanocoat™” leads to a longer, durable life of expensive machinery & equipment by protecting it from rust, thereby avoiding huge maintenance & replacement cost. The bonding & adhesion strength increases by 100% to 300% after using “steel guard nanocoat™”. It prolongs the life to a multi paint system because of its better bonding, curing, reforming and barrier properties as compared to other conventional primers making it a unique product in its category. Since “steel guard nanocoat™” is a water based solution, its viscosity is very low (1. 035) which leads to a much higher coverage leading to huge reductions in cost. Also since one layer is sufficient, it makes “steel guard nanocoat™”extremely cost effective & economical. Tmt bars treated with “steel guard nanocoat tm” are free from corrosion. “steel guard nanocoat tm” is a revolutionary invention based on nanotechnology (micro crystal development technology) wherein it works at the molecular level by penetrating inside the pores of the surface. It creates a dense crystal formation (frost) protective layer consisting of millions of nuclei. This layer acts as a barrier between the applied surface and atmosphere stopping the formation of fe2 & fe3 ions, which are the main agents of corrosion. The crystal layer thus formed is so closely interlinked & interwoven that it does not allow water & gas to penetrate inside. This phenomenon prevents corrosion and ultimate result in an increase in the bonding strength of steel with concrete. The detailed reasons for are mentioned below: simultaneously, billions of nuclei are formed on the surface and micro crystals start growing around them. This forms a very tenacious attachment with the sub stratum resulting in a formation of highly complex crystalline structure on the steel surface. Another important reason for the increase in the bonding strength by more than 300% is nanocoat's physiochemical structure, due to which the active chemical formulation hides the dense forest of micro crystals inside and form a chemical net which attracts minute cement particles. This forms a strong bond between steel & cement.
