“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.
  • Avoids repetitive repainting & restructuring of structures which saves on additional paints & labor cost.
  • The applied surface retains its original properties as no external coat (film thickness of 0. 2 micron under delta meter) is formed on its surface along with protecting it from rusting.
  • “Steel guard nanocoat™” can be applied easily by any unskilled worker and is a very user friendly product.

Q) How does “Steel Guard Nanocoat™” work?

  • “Steel Guard Nanocoat™” i works by forming a protective layer, consisting of millions of nuclei. On application of “Steel Guard Nanocoat™” i, a very compact & complex crystal arrangement is formed which creates a barrier between the surface & atmosphere, stopping the formation of Fe2 & FE3 ions which are the main agents of rusting. Peripheral Crystallization takes place along with Vertical Crystallization which results in a arrangement being “generated” through the surface and not above the surface. It acts on a molecular level penetrating into the very fine cracks & pores of the metal, forming a layer of water soluble compound which protects it from rusting.

Q) How does “Steel Guard Nanocoat™”stop the formation of rust?

  • Rust i.e. Ferrous Hydro Carbonates are formed when Fe3+ions react with water & CO2.“Steel Guard Nanocoat™” forms a complex crystal coat through the surface which is insoluble in water and closes the free valences of fe3+ ions. These micro crystals create their own space within the molecular gap of iron avoiding the formation of micro Anodes & Cathodes, thus prohibiting rust to form on the applied portion.

Q) What are the different stages “Steel Guard Nanocoat™” goes through after applying it on the surface ?

  • There are 3 major physical stages of “Steel Guard Nanocoat™” while it transfers from liquid steel guard to a strong, hard and tenacious crystal on the martensite surface.

Q) How does “Steel Guard Nanocoat™” improve the bonding strength of Steel ?

  • The Micro Crystal arrangement formed on application of “Steel Guard Nanocoat™” is so close & interwoven that it does not allow water & gas to penetrate. Such arrangement takes place in vertical, horizontal & lateral sides creating a tenacious & compact bond thus improving the bonding strength of steel with concrete, cement, paint & any external coat. The bonding strength increases 100% to 300% when the nanocoated construction steel is mixed with cement concrete.

Q) Doesn’t water in the presence of oxygen cause the metal to corrode or rust?

  • Yes, it does but the water used in “Steel Guard Nanocoat™” contains a rust inhibitor which prevents this from happening.

Q) Will “Steel Guard Nanocoat™” wash off in rains?

  • No. Once the coating is applied properly and kept to dry for an hour & cure for another 24 hrs, water or rain cannot remove the coating.

Q) Can “Steel Guard Nanocoat™” be removed after coating?

  • Yes. Heat the treated metal upto 600º C to loosen the grip of “Steel Guard Nanocoat™” and then brush it off with a wire brush.

Q) Can “Steel Guard Nanocoat™” protect from Acidic Fumes?

  • Yes. The applied portion, such as Industrial sheds, Structures, Pipes, and Corrugated sheets etc which are in direct / indirect contact with any acid & acidic fumes can be protected even at high temperatures. Please contact us for more details about this application.

Steel Guard Nanocoat acts on the martensite layer of the TMT rebars and forms a NANO COMPOSITE (Coat is generated from the martensite portion and Nanocoat does not form a layer / film on the surface separately.
There are 3 major physical stages of Steel Guard:
Nanocoat TM
while it transfers from liquid steel guard to a strong, hard and tenacious crystal on the martensite surface.

  • STAGE 1: In the beginning, Steel Guard Nanocoat TM possess a low viscosity , just like water when it is in contact with steel.
  • STAGE 2: Upton the 1st 4 – 6 hours, Steel Guard Nanocoat TM while reacting with steel makes a complex crystalline structure, becomes very sticky & viscose before the formation of fully mature crystals.

During this stage, water and other solvents in the formulas get evaporated and due to this evaporation and continuous reaction, Steel Guard Nanocoat TM becomes very sticky & viscose before the competition of the whole process.
  • STAGE 3: In this stage after 6 -10 hrs. though the Nanocoat seems to have dried, it does not dry actually and the process of forming Dense Forest of Micro Crystals is at its top speed. This process continues for the next 14 hrs. i.e. total of 24 hrs.

At this stage, Steel Guard coated surface should not come in contact with water because the prematurely developed micro crystals gets hydrated and change their colour to chalkish white.
Therefore, for the formation of inseparable NANO COMPOSITE, curing of 24 hrs. is essential. However, this curing time can be reduced further by applying different methods.
