What happens on the application of Steel Guard Nanocoat on Steel Surface?

  1. Nanocoat is water based. After its application on surface, water gets evaporated and active ingredients form millions of nuclei on activated surface. It forms a Dense Forest of composites on it, which is interwoven and a close crystal to crystal contact due to which water and vapor cannot penetrate through it and prevent rust.
  2. The dense forest acts "Activator" for crystal formation.
  3. Vertical and peripheral crystallization of nanocomposites is completed concurrently and is generated from the inner side of the surface and not from outside.
  4. This coats part of surface which remains stable at extreme atmospheric conditions.
  5. The formation of anode and cathode is blocked because of characteristics crystalline structure of nanocoat.
  6. Stops formation of Fe 2+ and Fe 3 + ions.
  7. Means stops formation of anodes and cathodes.
  8. Means galvanic current is not flowing through poles.
  9. Means no rusting, keeping base metal intact.
  10. The cracks, crevices, and micropores get activated by typical reaction of ingredients of nano coat with surface.

Summary

  • Rusting is the global concern.
  • Steel is the type of metal which corrodes very fast.
  • Steel is widely used material almost in every industry.
  • Steel is used widely in our personal life also.
  • A lot of surface treatment methods are available but do have limitations.
  • Hence treatment application is respective.
  • Shows that 3 to 4% of our GDP value is spent on corrosion.

Results of Gammery Test

If a galvanic cell is formed from any 2 metals in the above series then the metal higher up the series will be the cathode and the potential difference will be difference between the individual values of the normal electrode potentials for the anode and the cathode.

If copper and iron electrodes are immersed in electrodes are immersed in an electrolyte and connected together externally, the flow of current will in the dissolution of iron electrode because iron is anodic to copper. But if iron is used in conjugation with zinc the zinc will be consumed, since it is anodic to iron.

Naocoated Surface Magnified 1000 Times

Image of a nanocoated steel sample magnified 1000 times. The white particles are the densely formed crystals on the steel surface on applying Steel Guard – nanocoat.

The nanocoated steel sample was heated to 600°C and hammered. The sample was chiseled to remove coating from the surface of steel and observed under the microscope. Crystals visible show efficacy of nanocoat.

Benefits of Nanocoat

  1. Single layer of Nanocoat is sufficient.
  2. Rust already present on the surface gets converted into nanocomposite, which adheres paint and primer as well.
  3. Strongest adhesion of primer and paint with substrate.
  4. Increase in the gloss of paint.
  5. 'Peeling off' of paint from substrate is reduced drastically.
  6. Strong bond between primer/paint and substrate helps paint to fight against corrosion.
  7. Any skilled or unskilled person can apply the Steel Guard nano coat.
  8. 'Cross Cut' test results in laboratory show paint adhesion on nano coated surface of finest quality ASTM 4B.
  9. Cost reduction can be achieved by least maintenance.
  10. Nano coat helps in improvement of gloss after top coat to 85% to 95%.
  11. As DFT of nano coat is very less and crystal arrangement of Nano coat is very close (gap is <15 micron), it avoids corrosion by stopping incorporation of sodium chloride in between the crystal molecule requires 15-micron gap to insert in.
  12. Increases bond strength with cement and paint by upto 100%
