What nanotechnology does SmartGuardTM use?

Schild GmbH has found that many of the surface of the substrate itself is hydrophilic and insulating. Such a surface is easy to attract dust and build up dirt, so it is easy to get dirty. There are also many tiny holes on the exposed surface, so that external pollutants can easily remain in these holes, corroding the surface of the substrate, and also causing surface fading and cracking. Therefore, based on the above problems on the surface of the substrate, we use the following cutting-edge nanotechnology to make the ordinary surface of the substrate into a smart surface, thereby increasing the added value and advantages of the substrate.

1. Nano-sized polymer 

The high molecular polymer designed according to the specific application needs is uniformly dispersed in the form of colloidal particles in a suitable medium, and the diameter of the colloidal particles is on the order of nanometre.

2. Covalent bonding

The sharing of electrons between adjacent molecules forms a very strong chemical bond, which is a key reason for extreme durability.

3. Nanoscale

The nano-scale coating guarantees transparency, breathability, mechanical strength and chemical stability. The coating does not crack, peel or discolor.

4. Self-aggregation structure

The functional polymer is automatically aggregated into a neat monolayer at the surface of the material, and the thickness is only one molecule. The material has a predetermined function (hydrophobicity or oleophobicity) by reducing the surface energy of the material.

5. Surface energy

The lower the surface energy of the solid, the more the water droplets tend to reduce the mutual contact area when it comes into contact with , thereby increasing the contact angle until a spherical water droplet is formed. The larger the contact angle of the water droplets with the solid, the easier it is to roll off the solid surface under the action of gravity. A surface with a large contact angle is called a "hydrophobic" surface. Stains do not easily stick to such surfaces, so such surfaces are also referred to as "antifouling surfaces."
