Anticorrosive paint for metal - reliable protection against rust

Despite the fact that recently a lot of modern materials have been produced, which are manufactured according to the methods developed in the age of innovative technologies, the metal still does not plan to surrender its positions. But its specific characteristics dictate the need for the use in the construction industry of paint and varnish materials that would be able to prevent premature failure of surfaces.

Protection of metal

Today, metal structures are an integral part of multi-apartment buildings, where heating and water supply systems are installed. Country building is even more actively using similar structures, where they are realized in small architectural forms, bars on windows, gates and greenhouses. Consumers choose the metal based on its unique qualities, among them mechanical strength and resistance to high temperatures can be distinguished. Among other things, metal is relatively affordable. Despite the fact that it has many advantages, it has its own vulnerabilities, the presence of which determines the need for the application of paint on rust.

Methods for controlling rust

An anticorrosion paint for metal will be needed for you, if you want to protect structures from the relevant material and extend their life. Rust is the result of oxidative processes that occur on the surface of the material. The structures begin to undergo oxidation in those cases when a certain amount of water vapor is contained in the air, it is under their influence that the strength of the metal decreases, which loses its original attractiveness. Corrosion begins to penetrate inside, attracting moisture and retaining inside due to the porous structure. The most common for the protection of metal are traditional methods that provide for the initial cleaning of rust, as well as 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, as today economically advantageous and not so labor-consuming methods of protection against corrosion have been found. To avoid progressive deterioration paint and varnish compositions are used that interfere with the oxidation process.

Varieties of paintwork coatings for metal

If you need an anti-corrosion paint for metal, then you can consider the classification of such products. On sale you can find epoxy enamels, alkyd paints, oil and acrylic compositions. Epoxy enamels are used in everyday life quite rarely, because among their ingredients contain toxic substances. If it is necessary to protect the material from the effects of high temperatures, then a mixture should be preferred, which is based on silicone resins. In oil paints, the main component is drying oil and natural oils, they do not tolerate the effects of temperature changes, therefore they are intended for internal works. This limits the scope of their use, since oil paints are not able to provide proper protection of structures against corrosion.

Alkyd anticorrosion paints are used for application to galvanized surfaces. Such formulations have the highest adhesiveness, but they are not resistant to high temperatures. Among other things, mixtures of this type are extremely flammable. Most recently, acrylic paints for metal appeared on the market of building materials, but today they have gained their popularity, this is explained by the functionality of the characteristics. Anticorrosive acrylic paint for metal is versatile, because it can be used for internal and external finishing work. The compositions demonstrate the effectiveness of staining 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 for protecting the metal from corrosion is the rust paint of the Hammerite brand. It allows to refuse from carrying out labor-consuming and expensive works, which are not always justified. The aforementioned quick-drying one-component formulation is made on the basis of epoxy-modified synthetic resins, to which anticorrosive pigments are added. Use this mixture can be as a finish coat, which will have high decorative properties. These anticorrosion paints for metal after drying are glossy or semi-glossy. 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 the industrial industry. For example, with its help it is possible to protect roofing systems, water pipes, agricultural tools, machines and equipment.

Peculiarities of the use of Hammerite paint

The above paint for metal with anti-corrosion properties prevents the negative impact of water on the surface. The wetting properties of the mixture make it possible to apply even to unprepared bases. Products after drying can be operated with a sufficiently 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 damp and hot climates.

When it is not necessary to use an anti-corrosion paint

Despite the fact that anti-corrosion paint for metal has many advantages, it has some drawbacks. Among them, there should be a ban on processing equipment that will be used at temperatures above 150 °. Coating is excluded on structures whose surface will be in contact with drinking water.

Characteristics of the hammer paint

Anticorrosive paint for metal is now available 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 can have a glossy or semi-glossy shine, as well as a hammer and semi-tint shade. This coating got its name due to the fact that the surface visually resembles a hammer, which is distinguished by its roughness and metallic luster. Among the ingredients of the hammer paint: alkyd-styrene, epoxy and acrylic base. Among other things, the composition is supplemented with aluminum powder and fine glass. The hammer coating perfectly copes with fluctuations in temperature, as well as vibration. It can be processed with the help of industrial equipment and create an anticorrosive coating for non-ferrous and ferrous metals. Such anticorrosion paints have one undeniable 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 astringents.

Characteristics of enamel-primer "Rzhavostop"

If you need a paint for metal anticorrosive black, then you can prefer the enamel primer "Rzhavostop". Its application is possible directly on the rust, and the mixture is intended for the painting of cast iron and steel surfaces with remnants of retained rust. This includes metal structures, gratings, fences and metal garages. You can use this mixture for painting plastered surfaces. At 20 m ² will be enough for one kilogram of the mixture, which is true 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 this composition is 15 hours. The mixture can be tinted with pastes, but their addition is possible in a volume of not more than 10%. After drying, the surface becomes glossy. Paint is universal, as its application is possible outside and inside the premises. In addition, it is not necessary to use a primer at the initial stage, as for the rust converter. High protective properties will be preserved both on pure metal and on rusty surfaces. It is noteworthy that "Rzhavostop" can be applied to the remains of old paint and varnish coatings.

Aerosol paint

Treatment of metal anticorrosive paint is sometimes carried out from aerosol cans. Such paints are offered for sale in three varieties, among them: standard paint, double and universal. The first variety is used for simple staining in one layer, while the double paint for metal acts like enamel and primer. Its advantage is that before painting the surface, it is not necessary to apply a primer. Universal aerosol paint will act as a primer, rust converter and enamel. If you want to work directly on rust, then you should use the third version. One cylinder will be sufficient for application to the surface, the area of which is approximately 3.5 m ² . In this case, it will be possible to form a layer 0.05 mm thick. This explains the fact that aerosol paint is not used in large areas, it is more appropriate to use it for a small amount of work. As practice shows, it is especially convenient to use an aerosol paint to treat a damaged paint layer and to apply the composition to hard-to-reach places.

Paint of the brand "Silver"

Has a wide enough scope of modern anti-corrosion paint for metal, water impact, it is even capable of undergoing. This applies to containers, if they were processed by the composition "Silver". It is a waterproof enamel for 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 staining of steel and metal containers for water. The surface can be made of galvanized and ferrous metals. This paint has the ability to reflect the rays of the sun and to diffuse infrared radiation, which prevents the premature destruction of metal structures, roofs and hangars. This anti-corrosion coating for metal can be used to protect the supports of power lines, oil and pipelines, steel tanks, floating docks, as well as any metal structures that are operated in a humid atmosphere.

Conclusion

Anticorrosive paint for metal for cars is also on sale, as an example can be given "Plast anticorrosion", which also performs the function of protection from high temperatures. But the "Spetsnaz" replaces the ordinary enamel, primer and anticorrosion.
