Industrial Coatings | Metal Finishes | Nanokote

Supplier: Nanokote

Nanokote metal finishes can enhance stainless steel and light metals by enabling permanent functionality such as self-cleaning and exceptional corrosion protection.


These properties benefit manufacturers and end users alike. Permanent anti-corrosion coatings provide extreme chemical and abrasion resistance to extend the life of metals in harsh environments. Our coatings provide for low cost alternatives to PVDF and anodising as protection on aluminium. This is ideal for application on aluminium cladding due to the cost down approach verses PVDF coatings and the additional self-cleaning property.

Our coatings can also provide anti fingerprint and anti-scratch properties to metal finishing. These features enhance surfaces such as stainless steel and aluminium and put an end to unsightly scratches and fingerprints. Surfaces will be able to maintain their new appearance when coated with Nanokote's metal finishing.

Nanokote is revolutionary technology that in some cases can significantly enhance the lifespan and durability of metal objects and structures while in others can provide for a significant cost reduction in protection coatings. When one coat of Nanokote is applied as a metal finishing, it is able to modify the properties of the surface without significantly changing the look of the exterior due to its very low coating thickness (3 - 5 microns as a clear coat of 15 micron as a pigmented coating).

  • Benefits of Nanokote metal finishing include:
  • Non-stick surface resulting in a self-cleaning surface
  • Permanent anti-corrosion properties
  • Coatings provide extreme abrasion resistance
  • Extends the life of metals in harsh environments
  • Anti-fingerprint and anti-scratch metal finishing
  • Remains stable under high temperatures (in excess of 700C°)
  • Very cost-effective
  • Low cost alternative to traditional protection processes

Our metal finishing includes industry leading properties such as:

  • UV-light stable
  • Temperature resistant (-cycles) and thermal shock resistant
  • Stable against environmental influences (hydrolysis, weathering etc.)
  • Free of hexavalent chromium and other heavy metals
  • Produced in an environmentally friendly production process
  • Very low material consumption
  • Low cost
  • Improved coating properties
  • Greater than 100 degree contact angle with water
  • High chemical bonding energy with light metals and stainless steel
  • Single component coating materials
  • Wolf-Wilborn scratch hardness 8H (this is an effective anti-scratch coating)

Quality testings that have been conducted with Nanokote include the following:

  • Acidic humidity (30 Cycles, 0.2 SO2)
  • Constant humidity (1,000 h)
  • Salt-spray (>3,000 h)
  • Boiling test (2 h dest. Water)
  • UV-resistance (QUV 300 h)
  • Heat transfer

Nanokote metal finishing passes all tests listed above. Our coating shows no signs damage blistering, cracking, flaking or softening.

Heat exchanger example: 500 h salt-spray chamber

Nanokote's anti-corrosion coatings, provide permanent protection against tea staining, finger-prints and scratches. All are properties that are important when using light metals and stainless steel in production. Traditionally anti-corrosion coatings use dangerous heavy metals and require three separate coats including a primer, an epoxy coating and then a top coat polyurethane.

Overall this can amount to well in excess of 100 microns in coating thickness. This process not only impacts the visual nature of the metal surface but it also becomes a costly exercise from a coating consumption point of view and also a labour perspective. By comparison, Nanokote is a one coat process producing a coating thickness of only a few microns that does not require priming.

Metal finishing processing

Automated application of our anti-scratch, anti-corrosion and anti-finger print coating to stainless steel, aluminium coating, titanium and magnesium alloys can be carried out in a number of ways. In some cases we can electrostatically apply our coating materials in a similar fashion to powder coating. Other methods include spray application followed by heat to achieve full cure within two minutes and in some other cases spin coating. Spin coating is an option when a particularly thin, uniform coating is required.
