Metal paint for rust anti-rust: overview, types, characteristics, application and reviews

When carrying out repairs, one often has to face the need to paint metal products. A big problem in this case is that the metal is able to oxidize when exposed to moisture on its surface. In order to eliminate the rust, it is necessary to carry out mechanical cleaning, after which the base can be painted with rust-proof paint for corrosion protection, which is described below.

Solution

These manipulations are troublesome, and sometimes designs are not available for stripping rust. In order to ensure this process, manufacturers have taken care of creating rust paints that can be used as decorative coatings. These compounds are modern, they have a wide range of uses.

Reviews of anti-corrosion paints

The paint for metal on rust anticorrosive possesses set of advantages, among them consumers mark:

• Possibility of direct application to rust;
• Creation of a protective coating on the metal surface, which repels dirt and water;
• Good hiding power, high adhesion;
• Anticorrosive durability;
• Quick drying;
• Richness of colors.

However, it is worth highlighting the shortcomings, among them, consumers note the lack of the ability to paint objects that will be heated up to 150 ° C and above during operation. Among other things, according to customers, after painting the surface should not come into contact with drinking water or food.

Types of paints for rust

If you need an anticorrosive paint for rust, you should familiarize yourself with its basic types. In order to achieve the desired effect in the surface treatment, it is necessary to understand the areas of use of compositions for rust. These mixtures are classified according to the type of the main substance, the maximum temperature, and also the number of components. For example, on the market you can find waterborne paints, which contain phosphoric acid. For them you have to pay the least, but the stability of the surface to the environment will be minimal. Among other things, manufacturers also offer two-component compounds, to the ingredients of which are added epoxy resins, corrosion inhibitors and polyurethanes. Paint for metal on rust anti-rust can also be:

• Epoxy;
• Oil;
• Alkyd;
• Acrylic;
• Hammer.

Epoxy compounds are toxic, so they can not be used in everyday life. They are suitable for heated metal structures. The composition of oil mixtures contains natural oils and drying oil. The surface after drying will be characterized by low resistance to temperature effects. If the product is operated outdoors, the corrosion protection of the oil paint will decrease, therefore it is recommended to use these compounds indoors. Alkyd paint for metal on rust anti-corrosion is intended for galvanized metal, it is flammable, so it should not be used for heated structures. The application will be very simple, since the mixture has a high degree of adhesion.

Overview of paint features for rust

On sale, you can also find acrylic paint, which is suitable for highly heated structures. It can be used for heating elements both outdoors and indoors. Restore the rusted metal in a short time, you can use a special paint for rust, which contains three components. The process with this mixture will be cheaper, the application of paint can be carried out in a short time and even on the untreated surface. Among the ingredients contain anti-corrosive substances and resins. The paint dries quickly, and after the completion of this stage it will be able to protect the metal for 8 years.

Hammer paint allows you to achieve a rough surface with a metallic sheen. Among the ingredients contain alkyds, epoxides, aluminum powder and acrylic. Hammer blends can be used for non-ferrous metals, and a primer can not be applied before application. The first layer serves as a primer, while the second layer is anticorrosive. But the third one is used as an enamel. It is impossible to protect the surfaces with hammer paints, which will be heated during operation above 150 ° C.

Application Features

Anticorrosive paint for metal, the application of which must be carried out according to the instructions, is applied to the prepared surface. The substrate should be cleaned, degreased and dried, freed from the old layers of paint with emery or brushes for metal. From the large unevenness the master can get rid of the crusher. Experts recommend to make preliminary priming, which improves the quality of adhesion, making the layer more durable. If you use ground paint, then this step can be eliminated.

The next step is the application of paint, while remember that the temperature of the environment should vary within 20 ° C, the humidity should be 80%. The paint is thinned and diluted with a solvent, using the 9: 1 ratio. It is not recommended to apply more than three layers, the composition should not be dissolved with a nitrocellulose mixture. For work, you can use a spray gun, wait between the layers for 15 minutes.

Characteristics of paint ХВ-0278

If you are interested in the question of what properties the paint for metal has on the rust of grade ХВ-0278, then you should familiarize yourself with the information presented below. The hiding power of the dried film is a limit of 60 to 120 g / m ² , the final value will depend on the color. The hardness of the film by the pendulum is 0.15 mm. The coefficient of conversion efficiency of rust is 0.7, the resistance of the film to the static action of a solution of sodium chloride is 72 hours. These compounds are prepared according to specification 2313-174-21743165-2000.

Reviews of HB-0278

According to users, long-term protection with the XB-0278 can only be ensured if the metal structure does not come into contact with electrical solutions, capacitors and oxygen. The rusting center will be completely isolated after application of the paint. As another advantage of the described primer enamel, there is no restriction on the area and form of processing. Among other things, the protective coating has high decorative properties. The coating can be tinted in different colors. There is one more for such material as paint for metal and rust, characteristic. Its choice is justified if you need to protect a metal garage, a house roof, power lines or other types of buildings.

Conclusion

The above-described paint for metal on rust is anticorrosive, the price of which is 118 rubles. Per kilogram, is distinguished by its ability to protect construction and other structural elements from the negative impact of the external environment. The compositions described above are able to maintain performance in a wide temperature range: -50 to +80 ° C. This is also true if the structure is exposed to sudden temperature changes.
