Nano-coverages are substances, which serve for protection of surfaces made of various materials. The surfaces are protected from the negative impact of the surrounding nature and make it significantly easier to clean and maintain.
The products are made of main substances – nano-particles and carrier substances – water, solvents or compositions of liquid polymers. The nano-particles in our products are mainly silicon oxides, aluminium, zinc, manganese, titanium, tin, antimony and silver, as well as phosphates of lithium and iron. Depending on the surfaces, which they need to work on and their field of appliance, there are different combinations of the nano-materials, mentioned above.
Nano-coverages are divided in two different groups:
The first group of nano-coverage is created for smooth surfaces ( non-porous ones ). The carrier material is a composition of liquid polymers, which does not evaporate, doesn’t change its composition and after polymerizing it forms over the surfaces an optically invisible with unarmed eye film. The film’s width is 1-2 micrometers. It heavily keeps in the nano-particles from its composition and doesn’t allow their arrangement in terms of positioning to be spoiled. Due to the film’s small width, its surface gains the properties of the nano-particles that are a part of the composition itself.
The polymeric film is elastic and has high algebraic properties – its connection with the processed material is practically indestructible, but under the influence of external factors, especially under mechanical impacts with time, it gets worn out and its effectiveness decreases. The durability of the coverage is from 1 to 6 months, depending on the characteristics of the processed surfaces and the conditions under which they are being exploited. When the effectiveness of the coverage decreases, the surfaces are processed again.
The nano-coverage products of this type do not contain water. This allows them to be applied without any issues in a very wide temperature range. For an example, the hydrophobic coverage for building facades “Voka” can be applied in temperature levels of -30 to +80 degrees Celsius and the products for dry, waterless washing of cars can be used under various natural air temperatures.
On the other hand, the already formed surfaces work effectively in big temperature amplitudes. The car coverage and the glass coverage products can withstand easily temperatures in the range of -40 to +60 degrees Celsius. The kitchen coverage preserve their properties under temperatures of -50 to +300 degrees Celsius, which allows them to be used in the internal surfaces of fridges and freezers. They can also be used for anti-burns for ceramic surfaces of hobs, stoves, ovens, microwaves and grills. Cleaning the processed surfaces can be done only by using a wet towel, without and abrasive cleaning substances. Thanks to this property, the kitchen product is nominated and wins the award for “Best Cleaning Substance” in Canada for 2015. The amount of vaporous substances in the group is practically narrowed down to 0. Thanks to this fact, during the applying and polymerization of the coverage, there are no losses from evaporation. This is the reason why the consumption of the products is so low. It is approximately 3 grams per square meter. In order to form a proper quality protective layer, you need 1 gram per square meter and about 2 grams per square meter stays over the towel, which is being used for the appliance. The 100 gram pack is enough to create a long-lasting coverage over surfaces of 33 square meters. The exceptionally low consumption of these products and the fact that in them, there are no vaporous or soluble substances allows them to be safely utilized with the hard domestic disposals at the designated spots. There is no possibility for the nano-particles to come in a natural way in nature. This contributes not only for the protection and preservation of nature, but also creates a safe and healthy environment at home.
The second coverage group are water-based and are meant to process porous materials – concrete, stone, marbles, granite, wood, bricks, fibrous materials – textile, alcantara, leather, nubuck and more.
They go in deeply in the pores of the material and after the water evaporates, a cover is created around every fiber. The cover is resistant, insoluble made of nano-particles that have a width within the nano range. This way, the layer starts to isolate over the whole surface of the item and does not change its appearance and also doesn’t prevent air from going in. This way plasters and porous building materials can keep “breathing”, while the tissues and leather do not change their structure and the touch sensation.
Due to the fact that the coverage is formed completely out of nano-particles with no polymeric film, the duration of these coverage products is significantly longer than the duration of the 1st group coverage products. It effectively protects the materials from 1 year ( for leather and textile ) up to 15 years for the dual-component coverage for wood crafts. When the protective layer starts losing its efficiency, the materials are processed once again.
The carrier substance in this type of coverage is the water, which evaporates after the appliance. Because of this, the consumption is significantly higher than the products in the 1st group and varies between 25 to 100 ml per square meter, depending on the density of the processed materials. The bigger the density – the lower the consumption.
The formed coverage is chemically inactive, successfully the can withstand acids and bases and are safe for the surrounding environment, animals and people.
