The coating that makes the water droplets escape!

The continuous contact of water with various materials including glass, metal, and ceramic surfaces and building materials, etc. can be troublesome in our working or living environment, and may affect the soundness of the surfaces in addition to causing costs. As a result, different coatings have been developed to make surfaces hydrophobic. One of the most important features that a hydrophobic coating should have is to maintain the durability and function of the coating in a variety of environmental conditions such as rain, snow, sunlight, dust, and pollution. Nanotechnology has contributed greatly to the development of hydrophobic coatings.

Hydrophobic coatings act as a barrier against moisture and corrosion
Most building materials have very fine porosities and hydroxyl groups at their surfaces. These hydroxyl groups are water adsorbent due to their similarity with water structure as well as hydrophobic properties, so they are easily soaked and the water penetrates their surface.

On the other hand, the corrosion of metal and steel surfaces, especially in coastal areas, and the weakening of concrete building materials are major challenges needed to be addressed.

The advancement of science and the advent of technology have led to the production of materials with high durability. Among the different types of compounds, organosilanes are more considered as effective coatings in order to reduce the spontaneous absorption of moisture and to strengthen porous materials on the surfaces.


Nanotechnology barricades water droplets’ penetration
Silica nanoparticles with a high protective and biocompatible effect for making hydrophobic coatings have unique features. One of the most important features of these compounds is the production of transparent coatings that will not change the appearance of the sample after coating. This prevention of water and various contaminants penetration to the surface can impede their durability decrease and the change in the original appearance and soundness of the surface.

The main difference of this technology with other common technologies is the type of synthesis (sol-gel), the reaction raw material (organosilanes), and reaction solvent (ethanol), which results in a significant increase in production efficiency, speed, production process and the quality of the final product in proportion to alternative methods.

Moreover, due to the production of high durability coatings with coating capabilities by spray, roller and immersion methods, there is no need to make use of organic chemical environments, chemical catalysts and advanced equipment; therefore, the product is biocompatible and readily usable.

Nano Pad Sharif Co., as one of the pioneers in the field of nanotechnology in the country, has taken advantage of the results of many years of research and investigation in this field, which has taken a major step towards the production and development of general and industrial nano-coatings with unique features.

The company has succeeded in producing a hydrophobic solution suitable for coating on various substrates (glass, ceramics, cement and bricks, metals, textiles, etc.); where the products have a higher quality and lower actual cost over the similar samples.

By applying a nanocolloidal solution on the surface of glass and ceramics, it would have hydrophobic and self-cleansing properties and gets resistant to dirt types, so, the rainfall can clean the surfaces.

Applying this coating on the glass surface will lead to an increase in the angle of water droplets with the surface (more than 110 degrees), and this will cause slithering of completely spherical water (or rain) droplets onto the surface and washing the dirt from it.

Applying this coating on the surface does not make the glass opaque or shiny, and it can also protect indoor objects from the sunlight.

This product is usable in windows and glass facing, car’s glass and body, home appliances such as a hood and stove, bathroom and toilet and kitchen tiles, traffic lights and traffic control cameras, car lights, outdoor lights, street lighting, polymer faces of buildings and solar cell panels.


Here are some features and functions of the metal hydrophobic solution!
Nanocolloidal nano-coating prepared and produced for metals in Nano Pad Co., has been effective according to its compatible properties and formula on stainless alloy steels (stainless steel, aluminum, chromium, copper and brass) and, in general, all metals that can easily be corroded and rusted.

This solution is also suitable for metal surfaces used in restrooms and for stains due to the drying of water, which is mainly due to chlorine in water, preventing the change in the appearance of these surfaces. This product does not require any continuous washing and acid detergents.

This coating also prevents the formation of deposits and sediments on the metal parts as well as blurs on the surface of the metal.

In general, to highlight some of the advantages of this product, we can take account of preventing a change in the appearance of metal surfaces, increasing corrosion resistance and durability, static droplets on the surface and preventing the formation of chlorine stains on metal surfaces and the lack of need for continuous washing and use of acid detergents.


Does this product have the required approvals and permissions?
Nano Pad Sharif Company has also obtained the CE EROUP standard for glass, ceramic and metal hydrophobic products, in addition to the nanoscale approval of the Nanotechnology Initiative Council. The company also obtains ISO 900:2015, OHSAS 18001:2007 and ISO 14001:2015 standards.


Learn more about the hydrophobic solution of Nano Pad Sharif Co.
So far, many hydrophobic coatings have been made for different surfaces such as glass, ceramics, metal and so on. The most important feature of these products is the high durability and persistent after being applied to the surfaces.

Nano Pad Sharif’s hydrophobic nano-coatings have proven to be empirically and practically feasible in different atmospheric conditions and maintain their hydrophobic character, while many similar domestic and foreign products do not exhibit the same durability and persistence.

On the other hand, similar foreign products have a much higher cost, and this difference is sometimes up to five times that is not cost-effective.

Since the coatings produced in other countries are adapted to the climate of that region and is designed according to their weather conditions, the use of similar foreign products in Iran does not show the required efficiency and durability. Iran is a country with diverse climatic conditions, and each region has its own distinct atmospheric characteristics; from areas with high rainfall and humidity to arid and intense radiation areas or areas with industrial pollution or abundant dust. Therefore, the use of similar foreign products, even with the higher contact angle of the water droplet with the surface, do not have the needed persistence and quality due to the lack of durability and compatibility with the conditions of Iran, and may be separated from the surface after a while because of the light radiation, dust and pollution and therefore lose their functionality.

The products of Nano Pad Sharif Co. are designed to maintain their functionality in a wide range of climatic zones and behold their durability and persistence in the course of time.
