Organosilicon paint mainlyused to cover the facades. It consists of organic solvent pigments and additives, silicone resin. This mixture can be used both for businesses and in private homes. Helps to achieve a good appearance. Silicone paint is designed to protect against mechanical and thermal effects, as well as to prevent the ingress of excess moisture, which eventually destroys the material.
It is possible to paint the surface of concrete, asbestos cement andmaterials that are covered with plaster, perchlorovinyl silicone paints, various mixtures of foreign production, designed for the facade.
Most materials do not withstand moisture.Water slowly destroys its structure and strength, corrosion begins to appear. The temperature difference outside, constant melting and freezing again leads to the fact that the material is eaten and destroyed. Therefore, in the first place it must be protected from water. Organosilicon paint will be an excellent option for these purposes, it is waterproof, withstands severe temperature changes. It is made in chemical plants, color variations are huge, so everyone will find a suitable shade that will be visually pleasing and suitable for the whole building - you can choose any.
Before applying the paint on the facade of the building,it is necessary to carefully prepare the surface: clean it from dirt, then, best of all with an iron trowel, scrape off any irregularities. After the surface is sanded, you need to blow it with air, and a vacuum cleaner will do. There is no way that the material remains traces, cracks, wrinkles, drips or obvious spots of gaps in some places.
There is another rule, the humidity of concrete should notbe more than 8%. Paint is applied in several layers (mostly 2 or 3) with a brush, roller and sprayer, each with an hour or two difference. The first primer coat is diluted with xylene to a viscosity of 40 to 50 s (according to VZ-4), and after it dries, the paint is applied with a composition of viscosity from 60 to 100. The work is done with a brush or roller. If the viscosity is 50-60 s, then using a paint sprayer.
The mixture is made in the mixer.Paint is added first, after acrylate oligomers and fillers. All this is mixed for half an hour, then you get a uniform composition, the viscosity of which is about 14-16 s.
Today, silicone paintfor a facade it is in great demand because of high quality and a huge number of pluses, in comparison with other mixes. In addition to protecting the material being coated, it is able to bring positive properties.
Silicone facade paint enoughtoxic, so when working with it must first be instructed in safety. Under no circumstances should you violate the rules for working with this material. Otherwise, if it enters the respiratory tract, health can be injured, and negligence in work can affect the result as a whole.
The main difference is that in its own wayThe composition has not a carbon compound as usual, but an alternation of fixings of silicon and oxygen atoms. As is well known, in a chemical reaction, such compounds are incredibly resistant.
It is therefore not surprising that during the construction they prefer silicone paint, as it will last for a very long time, preserve the excellent appearance of the building and protect it.
Эмаль, созданная из двух основ (кремния и air) is synthesized. Therefore, it is durable. In its composition there are certain additives that help to achieve an excellent anti-corrosion effect. Also, to make the paint dry quickly, acrylic resins and ethyl cellulose are added to it.
Carbide layers are necessary in order toimprove strength and durability and avoid possible damage from the environment, which protects the silicone paint. Price will vary depending on these properties as well as color. But on average, the approximate cost will be from 120 to 300 rubles per bank. Susceptibility to temperature extremes is reduced by special hardeners. With the influence of aggressive chemicals fight epoxy resins, they will help to cope with them.
Sometimes it is necessary to paint a material that is used at maximum temperatures (over 100 degrees). For example, fireplaces, stoves, transformers.
Now manufacturers offer a variety of colors,which are able to withstand heating from 150 to 200 C. With regard to substances that can withstand higher temperatures, here their market is significantly narrowed. And only the silicone heat-resistant paint can remain resistant to temperatures over 200 C.
