Analysis of Liquid Armor
1.By silicon chemical reaction principle, Liquid Armor create a stable covalent bond with
silica glass, and make sharp protruding structure on the glass surface.
2.The formation of sharp protruding structure :Dry time is 8 hours at room temperature
and keep it away from water.
3.The formation of sharp protruding structure : Elevated temperature (80~150℃) will
accelerate structure formation. The temperature is higher, dry time is shorter.
4. Covalent bond is a strong chemical bond, and the bond energy is 150 KJ/mol.
5. Covalent bond, is 10 times stronger than hydrogen bond, is not easy to be broken due to
external force.

5. Nanotech Anti-fouling Coating Concept
Un-coated of blank glass Glass is coated by Liquid Armor
θ>100o and in the
shape of minute droplets
that roll away easily and
dirt does not appear to
accumulate.

6. Water repellent≠Smart Coating
1. First, we must have a concept. When we use coating, there is no perfect coatings that can keep dust and dirt away forever. The
6
current anti-fouling coatings can be called "easy to clean paint" or "self-cleaning coatings."
2. The best effect of commercially available water repellent is 6 months and the poor effect of them is 2 weeks. Water repellent
commonly is used in the car, 3C, mobile phone.
3. High-level water repellent, has added a lot of fluoride materials, is called "anti-finger coating“ that is used in 3C products.
4. Hydrophobicity (water contact angle) is the basic requirement for anti-fouling. Smart coating has many advantages, and
hydrophobic effect is just one of them.
5. We never see that the effect of commercially available anti-fouling coating is up to 1 year. The effect of our Smart Coating is 2
to 3 years.
6. Smart Coating, is designed for solar energy technology industry, has muti-function (anti-fouling – self-cleaning – easy to clean)
with four effects, eight characteristics and high standards of functional specifications. Smart coating can be applied to
traditional industries, including buildings, clean, car…etc.

7. Four effects of Liquid Armor
☆High durability
‒ The effect is more than over 18 months.
☆High anti-dirt performance
‒ Suitable for the regions which have lime-scale, dirt, grease
and dust.
☆High adhesion
‒ Suitable for glass, ceramics, tiles, and stone substrates.
The surface has good abrasion resistance, high hardness
and no peeling when applied Smart Coating.
☆High transparency
‒ Does not affect the appearance of the substrate color.
