Despite the fact that recently a lot of modern materials have appeared that are manufactured 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 make it necessary to use paints and varnishes in the construction industry that would be able to prevent premature failure of surfaces.
Metal protection
Today, metal structures are an integral part of multi-apartment buildings, where heating and plumbing systems are introduced. Suburban construction even more actively uses such structures, where they are implemented in small architectural forms, bars on windows, gates and greenhouses. Consumers choose metal based on its unique qualities, among them one can distinguish mechanical strength, as well as resistance to high temperatures. 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 to use paint on rust.
Ways to deal with rust
You will also need anticorrosion paint for metal 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 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, which loses its original attractiveness, decreases. Corrosion begins to penetrate, attracting moisture and staying inside due to the porous structure. Most often, traditional methods are used to protect the metal, which include initial cleaning of rust, as well as subsequent surface treatment with anticorrosive soil. At the final stage, the metal is protected by paint. But these measures are not always justified, because today found cost-effective and not so time-consuming methods of protection against corrosion. To exclude progressive destruction, paint and varnish compositions are used that interfere with the oxidation process.
Varieties of paint coatings for metal
If you need anticorrosion paint for metal, then you can consider the classification of such products. On sale you can find epoxy enamels, alkyd paints, oil and acrylic compounds. Epoxy enamels are rarely used in everyday life, since among their ingredients toxic substances are contained. If it is necessary to protect the material from high temperatures, then a mixture that is based on silicone resins should be preferred. In oil paints, the main component is drying oil and natural oils, they do not tolerate the effects of temperature extremes, therefore they are intended for internal use. This limits the scope of their use, since oil paints are not able to provide adequate protection of structures against corrosion.
Alkyd anti-corrosion paints are used for application on galvanized surfaces. Such compositions have the highest adhesive ability, but they do not differ in resistance to high temperatures. Among other things, mixtures of this type are extremely flammable. More recently, acrylic paints for metal have appeared on the building materials market, but today they have gained their popularity, this is due to the functionality of the characteristics. Anticorrosion acrylic paint for metal is versatile, because it can be used for internal and external finishing work. The compositions demonstrate effectiveness when painting even heating elements of heating and other parts that have a high temperature during operation.
Scope and characteristics of anticorrosion paints
One of the most popular means to protect metal from corrosion is Hammeraite rust paint. It allows you to refuse to carry out laborious and expensive work, which is not always justified. The above-mentioned quick-drying one-component composition is made on the basis of epoxy-modified synthetic resins, to which anti-corrosion pigments are added. You can use this mixture as a topcoat, which will have high decorative properties. These anti-corrosion paints for metal after drying acquire a glossy or semi-gloss shine. 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 be used to protect roofing systems, water pipes, agricultural tools, machines and equipment.
Features of the use of paint "Hammerayt"
The above metal paint with anti-corrosion properties prevents the negative effects of water on the surface. The wetting qualities of the mixture make it possible to apply even on unprepared substrates. After drying, the products can be operated at 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 wet and hot climatic conditions.
When not to use anti-corrosion paint
Despite the fact that anticorrosion paint for metal has many advantages, it also has some disadvantages. Among them, a ban on the processing of equipment that will be used at temperatures above 150 ° should be highlighted. Coating is excluded on structures whose surface will come into contact with drinking water.
Characteristics of hammer paint
Corrosion-resistant paint for metal is presented for sale today in a wide assortment. Having examined the products, you can also find hammer paints, the color palette of which includes many different shades. After drying, the surface may have a glossy or semi-gloss gloss, as well as a hammer and semi-matte shade. 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 are added to the composition. Hammer coating copes with temperature fluctuations, as well as vibration exposure. It can be used to 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, while preparing the surface is not necessary. As a result, it is possible to obtain an airtight protective film, which is formed due to binders.
Characteristics of enamel-soil "Rzhavostop"
If you need anti-corrosive black paint for metal, then you may prefer Rust-Stop enamel. Its application is possible directly by rust, and the mixture is intended for painting cast iron and steel surfaces with the remains of retained rust. These include metal structures, grilles, fences and metal garages. You can use this mixture for painting plastered surfaces. On 20 m 2 one kilogram of the mixture will be enough, which is true if the application is 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. The paint is universal, since its application is possible outside and indoors. 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 a rusty surface. It is noteworthy that Rzhavostop can be applied to the remnants of old coatings.
Spray paint
Metal processing with anti-corrosion 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 painting in a single layer, while double paint on metal acts as enamel and primer. Its advantage is that there is no need to apply a primer before painting the surface. Universal spray paint will act as a primer, rust converter and enamel. If you have to work directly on rust, then you should use the third variety. One bottle will be enough to apply to a surface whose area is approximately equal to 3.5 m 2 . In this case, it will be possible to form a layer with a thickness of 0.05 mm. This explains the fact that spray paint is not used in large areas, it is more appropriate to use it for a small amount of work. As practice shows, spray paint is especially convenient for treating a damaged paint layer and for applying the composition to hard-to-reach spots.
Serebrol brand paint
The modern anticorrosion paint for metal has a fairly wide scope, and it can even undergo water exposure. This applies to containers, if they have been processed composition "Serebrol." It is a waterproof enamel on metal, which is able to give the material high wear resistance, resistance to sea and fresh water, as well as oil and gasoline. This mixture is intended for coloring steel and metal containers for water. Galvanized and ferrous metals can act as a surface . This paint has the ability to reflect the rays of the sun and scatter infrared radiation, which prevents 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
Corrosion-resistant paint for metal for cars is also on sale, as an example, “Plast anticorrosive”, which also serves as a protection against high temperatures. But “Special Forces” replaces ordinary enamel, primer and anticorrosive.
