Despite the fact that recently appearedA lot of modern materials, which are made according to the methods developed in the age of innovative technologies, the metal still does not plan to give up its positions. But its specific characteristics necessitate the use of paints and varnishes in the construction industry, which would be able to prevent the premature failure of surfaces.
Metal protection
Today metal structures arean integral part of multi-apartment buildings, where heating and plumbing systems are implemented. Suburban construction is even more actively using such structures, where they are implemented in small architectural forms, lattices on windows, gates and greenhouses. Consumers choose the metal based on its unique qualities, among them mechanical strength, as well as resistance to high temperatures. Among other things, the metal is relatively affordable. Despite the fact that it has many advantages, it has its own vulnerable sides, the presence of which determines the need to use paint over rust.
Ways to combat rust
Anti-corrosive paint for metal is needed andto you, if you want to protect structures from the appropriate material and extend their life. Rust is the result of oxidative processes that occur on the surface of a material. Structures begin to undergo oxidation in cases where a certain amount of water vapor is contained in the air, it is under their influence that the strength of the metal, which loses its original attractiveness, decreases. Corrosion begins to penetrate inside, attracting moisture and holding inside due to the porous structure. Most often, traditional methods are used to protect the metal, which provide for the initial cleaning of rust, as well as the subsequent surface treatment with anti-corrosion primer. At the final stage, the metal is protected by paint. But these measures are not justified in all cases, because today cost-effective and not so labor-intensive methods of protection against corrosion have been found. To eliminate the progressive destruction of applied paintwork, which interfere with the oxidation process.
Varieties of paint coatings for metal
If you need anti-corrosion paintmetal, then you can consider the classification of similar products. On sale you can find epoxy enamel, alkyd paints, oil and acrylic compounds. Epoxy enamels are used in everyday life quite rarely, since their ingredients contain toxic substances. If it is necessary to protect the material from exposure to high temperatures, then you should prefer a mixture that is made on the basis of silicone resins. In oil paints, linseed oil and natural oils are the main component, they do not tolerate the effects of temperature changes, and therefore are intended for interior work. This limits the scope of their use, as oil paints are not able to provide adequate protection of structures against corrosion.
Alkyd anticorrosion paints are used forgalvanized surfaces. Such compositions have the highest adhesive ability, but they are not resistant to high temperatures. Among other things, mixtures of this type are extremely flammable. Quite recently, acrylic paints for metal appeared on the building materials market, but today they have gained their popularity, this is due to the functionality of the characteristics. Anticorrosive acrylic paint for metal is universal, because it can be used for internal and external finishing works. The compositions demonstrate the effectiveness when painting even heating elements of heating and other parts that have a high temperature during operation.
Area of use and characteristics of anti-corrosion paints
One of the most popular means to protectmetal from corrosion acts paint rust brand "Hammerayt". It allows you to abandon the labor-intensive and expensive work, which is not always justified. The aforementioned quick-drying one-component composition is made on the basis of epoxy-modified synthetic resins, to which anti-corrosion pigments are added. This mixture can be used as a finishing coating, which will have high decorative properties. The given anticorrosive paints on metal after drying gain glossy or semi-gloss gloss. And the main advantage of this coating is the ability to resist pollution, because they play an important role in the formation of rust. This composition is used in private construction, as well as in industrial industry. For example, it can help protect roofing systems, water pipes, agricultural tools, machinery and equipment.
Features of the use of paint "Hammerait"
The above paint on metal withanti-corrosion properties prevents the negative effects of water on the surface. The wetting qualities of the mixture provide the possibility of applying even on unprepared bases. Products after drying can be operated at a fairly wide temperature range, which varies from -20 to + 80 °. This paint is resistant to destruction even under the influence of ultraviolet rays, which is why it can be used in wet and hot climatic conditions.
When not to use anti-rust paint
Despite the fact that anti-corrosion paint onMetal has many advantages, it has some disadvantages. Among them, a ban on processing equipment that will be used at temperatures above 150 ° C should be highlighted. Coating is excluded on structures whose surface will be in contact with drinking water.
Hammer paint characteristics
Антикоррозийная краска по металлу представлена Today, for sale in a wide range, having examined the products, you will be able to find hammer paints, the color palette of which includes many different shades. After drying, the surface may have a glossy or semi-gloss luster, as well as a hammer and semi-gloss tint. This coating got its name due to the fact that the surface visually resembles a hammer head, which is characterized by roughness and metallic luster. Among the ingredients of hammer paint: alkyd-styrene, epoxy and acrylic bases. Among other things, aluminum powder and small fraction glass is added to the composition. The hammer cover copes with temperature fluctuations, as well as vibration exposure. It can process industrial equipment and create a corrosion-resistant coating for non-ferrous and ferrous metals. Such anti-corrosion paints have one indisputable advantage, which is expressed in the possibility of applying the composition directly to rust, and there is no need to prepare the surface. As a result, it is possible to obtain an airtight protective film, which is formed due to binders.
Characteristics of the enamel-soil "Rzhavostop"
If you need paint on metalanti-corrosion black, then you may prefer the enamel-primer "Rzhavostop". It can be applied directly to rust, and the mixture is intended for painting iron and steel surfaces with residues of retaining rust. These include metal structures, grilles, fences and metal garages. You can use this mixture for painting plastered surfaces. At 20 m2 one kilogram of the mixture will sufficetrue if the application will be carried out in one layer. Depending on the characteristics of the surface, the flow rate can be increased, then one kilogram will be enough for only 10 m.2. The drying time of such a composition is 15 hours.The mixture can be tinted pastes, but their addition is possible in a volume of not more than 10%. After drying, the surface becomes glossy. The paint is universal, as its application is possible inside and outside the premises. Additionally, there is no need to use a primer at the initial stage, as is the case for the rust converter. High protective properties will be maintained both on the pure metal and on the rusty surface. It is noteworthy that "Rzhavostop" can be applied to the remnants of old paint and varnish coatings.
Spray paint
Metal treatment with anti-rust paint sometimesIt is carried out from aerosol barrels. Such paints are presented for sale in three varieties, among them: standard paint, double and universal. The first variety is used for simple staining in one layer, while double paint on metal acts as enamel and primer. Its advantage is that before painting the surface there is no need to apply a primer. Universal spray paint will act as a primer, rust remover and enamel. If you have to work directly on rust, then you should use the third type. One cylinder will be sufficient for application to a surface whose area is approximately equal to 3.5 m2. It will be possible to form a layer thickness0.05 mm. This explains the fact that the spray paint is not used on large areas, it is better to use it for a small amount of work. As practice shows, the aerosol paint is especially convenient for processing the damaged paint layer and for applying the composition to hard-to-reach places.
Paint brand "Serebrol"
It has a wide range of applications.modern anti-corrosion paint on metal; it is even capable of undergoing water impact. This applies to containers, if they were treated with the composition "Serebrol." It is a waterproof enamel on metal, which is able to give the material high durability, resistance to sea and fresh water, as well as oil and gasoline. This mixture is intended for painting steel and metal tanks for water. Galvanized and ferrous metals can act as the surface. This paint has the ability to reflect the rays of the sun and diffuse infrared radiation, which prevents premature destruction of metal structures, roofs and hangars. This anti-corrosion coating for metal can be used to protect power line poles, oil and pipelines, steel tanks, floating docks, as well as any metal structures that are operated in a humid atmosphere.
Conclusion
Anticorrosion paint on metal for cars toois present in the sale, as an example, "Plast anticorrosive", which also performs the function of protection against high temperatures. But "SWAT" replaces ordinary enamel, primer and anticorrosive.
