Definition - What does Nano Coating mean?
A nano coating refers to very fine, thin layers of polymeric chemical substances used to impart specific corrosion resistance, chemical and physical properties to a substrate surface. They are primarily used to change the hydrophobic and/or oleophobic properties of a surface by applying a protective coating on a significantly small scale of several microns.
A nano coating is also known as a nanotechnology coating.
Corrosionpedia explains Nano Coating
Nano coatings are used on a wide variety of substrates, including metals, glass, ceramics and polymers.
Some benefits of nano coatings are:
- Reduced need for substrate maintenance activities to prevent corrosion
- Reduced labor and material costs
- Prolonged substrate lifespan and application use
- Increased substrate resistance to temperature fluctuations
- Substrate waterproofing
- Ultraviolet (UV) stability and abrasion resistance
These coatings are widely used to protect pipes and structures buried in the soil or immersed under water, as is typical for offshore oil rigs and platforms and other corrosive environments.
