Nano coating and its special properties for almost any application

From automotive to food processing and from interiors to textile: a nano coating is useful in almost any sector. Not only does nano coating seal the car lacquer but also makes the windows of a skyscraper self-cleaning. In this article we will take a look at the many possibilities liquid nano coatings offer.

To provide you with an idea of whether nano coating is what your project needs, we’ll give you 5 examples of benefits the coating can bring along. Nano coating:

  1. Decreases cleaning costs: grease and dirt slides off windows and solar panels.
  2. Prevents short-circuits: ideal for electronic uses and electrical systems.
  3. Increases safety: dangerous fungi and bacteria cannot attach to the surface.
  4. Slows down wear: durable protection for sensitive and porous surfaces such as concrete bridges and monuments.
  5. Protects from vandalism: becomes an effective anti graffiti or anti urine layer.

These properties are made possible by using nanotechnology which makes use of tiny nano particles. Therefore, the coating does not form a layer on the substrate like traditional coatings, but becomes one with the surface instead. Due to this, liquids no longer penetrate the surface, and dirt, grease and mould cannot adhere.

3 steps to take when defining the best nano coating product for the project

When opting for a nano coating for your project, you should keep in mind the purpose and material of the substrate: wood, glass, concrete and metal all require different products. For example, you should apply a ceramic coating on car paint, and a water repelling, self cleaning nano coating for windows.

Here we will bring you closer to the most suitable nano coating through the following 3 steps.

Step 1: What effect the coating should have

Essentially, the main types of effects nano coatings can have, depending on the chemical composition and ingredients, are hydrophobic, hydrophilic, oleophobic and nano coatings based on glass or ceramics.

Therefore, it is crucial to first determine, what you expect from the coating.


1. Self cleaning

Suitable coating: Hydrophilic coating
What it is: this nano coating is based on titanium dioxide and it is suitable especially for smooth surfaces. Titanium dioxide breaks almost any organic bond in UV light. It does not repel water, but attracts it instead; creating a thin, tiny water filter which creates a self-cleaning effect. The coating is extremely hygienic; you will literally see water and dirts slide off the surface.

Possible applications: skyscraper windows, medical instrument, solar panels and greenhouses.

2. Waterproof  and dirt repellent

Suitable coating: Hydrophobic and oleophobic
What it is: hydrophobic and oleophobic literally mean afraid of water and afraid of oils. The effective ingredient in these coatings is silicium dioxide which prevents water and contaminants from adhering to the surface. This type of nano coating is available for nearly any surface: the most common applications take place on bathroom floors and walls, but they are also applied to make textile waterproof.

Possible applications: car windows, walls and floors in the food processing industry, eyeglasses, sanitary facilities, textile, plastic, exterior furniture etc.

3. Resistant to impact

Suitable coating: Glass- or ceramic coating
What it is: like hydrophobic and oleophobic coatings, also ceramic and glass coatings are based on silicium dioxide; however, the dosis is higher. This makes the nano coating extremely hard, almost insoluble and resistant to a wide range of chemicals. Due to the extreme hardness of the coating, it is also somewhat resistant to impact and scratches. Therefore, it is one of the most popular nano coatings in the automotive coating and refinishes sectors.

Possible applications: Car paint, statues, machines, as a top coat on floors and walls.


Step 2: On which substrate the coating is applied

Even though nano coatings are suitable for almost any substrate, not every coating adheres to all substrates. The optimal adherence is created by adding ingredients that support adhering to the wished material such as smooth metal or porous concrete. Therefore, the products are  also often named according to the substrate they are suitable for: for example Nano Concrete, Nano Plastic and so on.

It is thus important to choose for a product that is especially developed for the surface you wish to coat. If you anyway choose for a product that is made for a different substrate, the coating may not adhere and the effect may not be as wished.

Step 3: Which professional products are available

Once you know which nano coating you need, it is time to purchase the coating. For commercial and industrial nano coating applications, you should look for a product that is designed for those applications. A consumer product does its job in a bathroom or kitchen, but skyscraper windows require a product with higher quality formula.

Consider these 5 facts before applying nano coating

Even though nano coatings are known for their many benefits, they also have a less beneficial side: keep in mind that nanocoatings are not always the right solution. You should consider at least the following 5 things before deciding to go for nano coatings.

  1. Easy to clean: nano coating are however not resistant to harsh cleaning chemicals and microfibre cloths.
  2. Type of substrate: every substrate requires a different nano coating.
  3. Limited durability: nano coatings are not for ever. Some products may deteriorate very fast and need another layer shortly after the first is applied.
  4. Contamination: the coatings are not suitable for old, contaminated substrates. The substrate must be absolutely clean.
  5. Product names: the names manufacturers give their products may be confusing; anti graffiti and glass coating are most often names of nanocoatings.

The latest medical and environmental innovations powered by nano coatings

Nanotechnology is the bases of many innovative experiments and prototypes. For example hospitals make use of nanotechnology in antimicrobial floor and wall coatings. Next to that, medical equipment and implants can be nano coated to make them safer. The newest innovation that can improve the processing in the medical sector is graphene nano coating; the graphene coating however, still needs further research and development before it can be brought to the market.

Nano coatings also contribute to improved and cleaner environment; they are used as anti urine coating which prevents the fluid from adhering to the surface, and as anti vandal graffiti paints which make removing graffiti easy.
