If a few years ago, between the protective coating of the car body were the main coatings based on waxes, today is the bestseller ceramic compositions, also known as "liquid glass." We are aware, the chemical composition of media for the body and found that the prices.
However, as the wise people say - all you will have to pay. This coating is quite expensive and difficult to use. And some can be used only professionally trained people in special circumstances - they're not yet available for sale, just for garages.
The fact is that such a ceramic coating is the result of a serious work of chemists. Among other things, the composition uses a nano-elements. It is clear that the word "nano" in relation to any product, which is today, if not laughter, then a fair question: too much appeared products with this "fashion accessory" in the title.
But in some of the ceramic coating, nano titanium dioxide powder, for example, to improve the grip of alcohol and drug film, so in this case "nano" is not an empty sound.
Today there are a lot of "ceramics" drugs. But at the heart of them - the common sand. Of course, not the sand (i.e. silica) and silicates, i.e. salts of silicic acid. We are all familiar with the silicates: for example, alkaline solutions of potassium silicate and sodium silicate - this is paper, glue or "liquid glass".
By the way, the first liquid glass was obtained in 1818 by the German chemist and mineralogist, Jan Nepomuk von Fuchs. And there is no way I think that his product will be used for the protection of the car bodies. In addition to this, the car then was not...
For almost 200 years, the chemistry has gone far ahead in preparation for the quartz-ceramic crowns are a complex mixture of substances, which then is not: in particular, a group of compounds based on silicon: silicones. And many other things.
Here is the structure of a typical "nanoceramic" liquid glass:
1) TiO2 - titanium dioxide: up to 3.0 %
Compounds that are used in the chemical industry for bleaching (in the case that it is in the meat of the squid, chewing gums, dragées, and other "white" products, as well as in the expensive paper), but also for thermal protection in the composition of the plastic and glass. It is obvious that the last property of the titanium oxide in our case plays an important role, and very fine particle size, which allows you to add a prefix "nano".
2) SiO2 - silicon dioxide (in the form of a mineral is quartz): up to 30%
On the basis of the coating - colorless crystals, which have high hardness and strength.
3) C10H30O5Si5 - decamethylcyclopentasiloxane (D5): more than 50% of the
Liquid silicone, which is resistant to oxidation. In industry is used for the chemical cleaning of textiles.
4) Al2O3 - aluminum oxide: less than 2%
A colorless water-insoluble crystals. Serves as raw material for the production of refractory and abrasive materials.
5) Alkoxysilane: 12%
Used in the synthesis of organosilicon products for creating organic polymeric film.
6) surfactant (Copolymer surfactant), less than 1%
Surface-active substances, is the Foundation of all detergents that, relatively speaking, the "push" of the contamination on the surface forms the substance of the film.
In principle, in varying degrees, these compounds (or their equivalents) that are used in almost all preparations. Something added, something is removed but the silicon is always present.
The process of using (this is also called "ceramic polishing") is practically the same for all drugs:
Manufacturers often claim a lifespan of up to 3 years, but according to examine numerous reviews, averaging coating to be updated more often - about once a year, provided day to day operation of the vehicle.
This would make it possible to perform a more reliable test, but this is expensive pleasure, because you need more of the same vehicles in the same conditions. This is possible, strictly speaking, only in the laboratory. Yet even this Grand consumer tests such as the American companies Consumer Reports does not attend for such tests, so today is that it is based on subjective estimates.
To get started, but during the week the car should not be washed at all because the coating is not yet fully formed. Some manufacturers recommend even longer-term abstinence - 2-3 weeks and it might be worth considering. After this period, the shadow will linger less, so if you wash on a regular basis, this will be enough for flushing. In view of the fact that it is a cheap self-service car washes are pretty wide, machine costs, it is possible to limit the 100-200 rubles per week.
Note that abrasive, that is dirty rags and brushes, should be avoided to not interfere with the smoothness of the coating. However, like ceramics, do not care, and in time, the coating still grow turbid.
If you have money, is the question: to strike or not to strike - not worth it, because the ceramic protective coatings really work. The price you now know of about 20 000 per year. For savings in the purchase of the course, the cheaper the funding or that is stored in the application trying to poland is an independent body, which is not recommended. Then it is generally easier to leave the body, without any protection.
