Nano Coating Australia

Benefit from the water- and grease-repelling properties of nano coating

From food processing to automotive and from textile to exterior, a nano coating is useful in almost any sector. Not only do nano coatings seal and protect car paintwork, they can also make the windows of a skyscraper self-cleaning. A nano coating does not form a layer on the substrate like traditional coatings, but becomes one with the substrate instead, forming bonds on a nanoscopic level. Due to this, liquids can no longer penetrate the surface and dirt, grease and fungi cannot adhere – it becomes either a hydrophobic coating or a hydrophilic coating, depending on its composition.

To provide you with an idea of whether nano coating is what your project needs, here are five examples of the benefits nano coating:

1. Reduces cleaning costs | Grease and dirt slides off windows and solar panels. Cleaning becomes safe and cost efficient with nano glass coating and other products.
2. Increases general safety | Dangerous fungi and bacteria cannot attach to the surface thanks to antimicrobial additives.
3. Prevents vandalism | Becomes an effective anti graffiti or anti urine layer where the harmful substrate cannot attach to.
4. Protects from short-circuits | Ideal for electronic uses and electrical systems.
5. Slows down deterioration | Durable protection for sensitive and porous surfaces such as concrete bridges and monuments.

Find the right nano coating for your project in 3 steps

When choosing the nano coating for your project, you should keep in mind the purpose and material of the substrate: glass, wood and concrete all require slightly different products. For example, your car may require a nano glass coating for paint protection, whereas the car windows need a nano coating spray for glass. There are three basic steps to choosing the right nano coating for your project:

STEP ONE: Define what you want from the nano coating

The main properties nano coatings have depend on the chemical composition and ingredients of the coating. Nano coatings are versatile and can be used as a hydrophobic coating, a hydrophilic coating, an oleophobic coating, or even scratch resistant coatings. First off you need to know what you want to achieve.

1. Self-cleaning

Suitable coating: Hydrophilic coating
Examples of applications: Self cleaning glass for skyscraper windows, nano coating for glass, medical instrument, solar panels and greenhouses.
What it is: This nano coating is based on titanium dioxide and it is suitable especially for smooth surfaces. Titanium dioxide makes the coating self cleaning because it breaks down organic bonds in the presence of UV light. It is also highly wettable, which means water is attracted to the surface and washes the unbonded contaminants away. This is the process behind self cleaning glass. Australia has a number of projects which utilise this technology including Martin Place skyscrapers in Sydney CBD. The coating is also extremely hygienic, and hydrophilic coatings are used to lubricate medical devices.

2. Dirt- and water-repellent

Suitable coating: Hydrophobic coating and oleophobic
Examples of applications:  Car windows, walls and floors in the food processing industry, eyeglasses, sanitary facilities, textile, plastic, exterior furniture etc.
What it is: Hydrophobic and oleophobic literally mean afraid of water and afraid of oils. The effective ingredient in these coatings is silicon 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 textiles and bathroom floors and walls, but it is also available as nano coating for glass.

3. Resistant to impact

Suitable coating: Glass- or ceramic coating
Examples of applications: Car paint, statues, machines, as a top coat on floors and walls.
What it is: Like oleophobic and hydrophobic coating, ceramic and glass coatings are also based on silicon dioxide or silica, however they have a higher concentration. This makes the nanocoating 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 used as nano glass coating in the automotive coating and refinishes sectors.

STEP TWO: Pick a product that suits your substrate

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 adhesion to the particular substrate such as smooth metal or porous concrete. Therefore, the products are also often named according to the substrate for which they are suited, for example Nano Concrete, Nano Plastic, Nano Coating for Glass and so on.

It is crucial to choose the product that is specially developed for the surface you wish to coat. If you choose a product that is made for a different substrate, the coating may not adhere and the effect may not be as wished. Keep in mind that nano coatings are not suitable for old, contaminated substrates. The substrate must be absolutely clean. They are also susceptible to damage from harsh cleaning chemicals.
