EZ Armor Coatings

EZ Armor

EZ armor is a hydrophobic surface treatment formulated to produce water repellant and oleophobic properties when applied to glass substrates. The product contains an amphiphilic polymer dispersed in mineral spirits. When applied to glass, the polymer reacts with the substrate via a moisture activated sol-gel chemistry.

Hydrophobic Coatings

What is hydrophobic surface impregnation?  

The hydrophobic coating consists of a nano-structure coating applied to the surface and can not to be seen with naked eye. What you see is a beading, water repelling effect.

Water forms beads on the treated surface. After treating, the nano-structures form a breathable, durable adhesion with the surface. The new Easy-to-Clean surface is now easily maintained, optically clear and stain-resistant.


The life span of the coating depends on user habits. The nano-structure adhesion with the surface is solid, durable and gives an easy-to-clean effect that acts like Teflon. If you use heavy abrasives, strong alkaline, strong acid or brushes, the coating will be damaged, and could damage the surface itself.


For maintenance, it is sufficient to wipe the glass with a cotton towel or a glass squeegee. Soap and dirt particles are easily removed and the clear beading effect will be preserved.

Is the coated surface self-cleaning?
In truth, no product is self-cleaning, but the cleaning will be easier and less frequent due to the hydrophobic properties of the nano-impregnation coating.

  • The hydrophobic coating beads dirt and water so that all runs off without adhesion to the surface.
  • The impregnation forms a breathable, durable bond with the surface and reduces stains, calcium buildup, etching and lime residue.
  • Do not use abrasives, alkaline, acid or brushes.
  • For shower glass, please allow sufficient air flow to dry.

Oleophobic Coatings

(Oleophobic Surface Impregnation)

What is oleophobic surface impregnation?  

Oleophobic surface impregnation is considered the “Holy Grail” of surface technology. Technically, oleophobic coatings are extremely difficult produce. Surface tension measures the tendency of the molecules of a material to group together. Water beads easily because it has a high surface tension. Oil spreads because the surface tension is low. To put it another way, water runs off a duck’s back while oil sticks to the feathers.

Hydrophobic materials are easily found in nature. The lotus leaf, grass and human hair are perfect examples of this. The surface tension of oil is so low that there are no naturally occurring oleophobic materials.

EZ Armor’s scientists have created oleophobic technology by adapting the nanotechnology of hydrophobic coatings to counteract the low surface tension of oil.

What does this mean?

This means that you get an easy-to-clean surface that repels oil. The surfaces that before were always soiled and difficult to clean are now Armored. Fingerprints and smudges are reduced and easily cleaned. No more harsh chemicals and dangerous solvents. Depending on the surface and regular maintenance, the protection could last a lifetime.

The Miracle of the Lotus

The Lotus Effect


The Lotus Effect refers to the very high water repellency (superhydrophobicity) exhibited by the leaves of the lotus flower. Dirt particles are picked up by water droplets due to a complex micro- and nano-scopic architecture of the surface, which minimizes adhesion.

Although the self-cleaning phenomenon of the lotus was known in Asia for more than 2000 years, its mechanism was explained only in the early 1970s after the introduction of the scanning electron microscope.


Functional Principle

Due to their high surface tension, water droplets tend to minimize their surface trying to achieve a spherical shape. On contact with a surface, adhesion forces result in wetting of the surface. Either complete or incomplete wetting may occur depending on the structure of the surface and the fluid tension of the droplet. The cause of self-cleaning properties is the hydrophobic water-repellent double structure of the surface. This enables the contact area and the adhesion force between surface and droplet to be significantly reduced resulting in a self-cleaning process. This hierarchical double structure is formed out of a characteristic epidermis and the covering waxes. The epidermis of the lotus plant possesses papillae with 10 to 20 µm in height and 10 to 15 µm in width on which the so-called epicuticular waxes are imposed. These superimposed waxes are hydrophobic and form the second layer of the double structure.

The hydrophobicity of a surface is related to its contact angle. The higher the contact angle the higher the hydrophobicity of a surface.Surfaces with a contact angle < 90° are referred to as hydrophilic and those with an angle >90° as hydrophobic. Some plants show contact angles up to 160° and are called super-hydrophobic meaning that only 2–3% of a drop’s surface is in contact. Plants with a double structured surface like the lotus can reach a contact angle of 170° whereas a droplet’s actual contact area is only 0.6%. All this leads to a self-cleaning effect.


Dirt particles with an extremely reduced contact area are picked up by water droplets and are thus easily cleaned off the surface. If a water droplet rolls across such a contaminated surface the adhesion between the dirt particle, irrespective of its chemistry, and the droplet is higher than between the particle and the surface. As this self-cleaning effect is based on the high surface tension of water it does not work with organic solvents.

This effect is of a great importance for plants as a protection against pathogens like fungi or algae growth, and also for animals like butterflies, dragonflies and other insects not able to cleanse all their body parts. Another positive effect of self-cleaning is the prevention of contamination of the area of a plant surface exposed to light resulting in a reduced photosynthesis.


Nanotechnologists have developed treatments, coatings, paints, roof tiles, fabrics and other surfaces that can stay dry and clean themselves in the same way as the lotus leaf. This can usually be achieved using special fluoro-chemical or silicone treatments on structured surfaces or with compositions containing micro-scale particulates.

As self cleaning of superhydrophobic microscopic to nanoscopic surfaces is based on a purely physio-chemical effect it can be transferred onto technical surfaces on a biomimetic basis. Our EZ Armor™ System is an example of the products with superhydrophobic self-cleaning properties.

Further applications have been marketed, such as self-cleaning glasses installed in the sensors of traffic control units on German autobahns. Lotus effect superhydrophobic coatings applied to microwave antennas can significantly reduce rain fade and the buildup of ice and snow.

Some “Easy to clean” products in ads often mistakenly claim the self-cleaning process of the lotus-effect. While the technology is based from the Lotus Effect, occasional cleaning and proper maintenance are still required.
