When carrying out repairs,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 rust, it is necessary to carry out a mechanical cleaning, after which a paint for rust-corrosion-resistant metal can be applied to the base, which is described below.
These manipulations are troublesome, and sometimesDesigns are not available for stripping rust. In order to provide this process, manufacturers have taken care of the creation of paints for rust, which can be used as decorative coatings. These compounds are modern, they have a wide range of uses.
The paint for metal on rust anti-corrosion has many advantages, among them consumers note:
However, it is worth highlighting the shortcomings, among themconsumers note the lack of the ability to paint objects that will be heated up to 150 ° C or higher during operation. Among other things, according to buyers, after painting the surface should not come into contact with drinking water or food.
If you need paint for metal byrust anti-corrosion, you should familiarize yourself with its main 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 the number of components. For example, on sale it is possible to meet water-diluted paints in which structure there is a phosphoric acid. For them it is necessary 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 compounds are toxic, so in their everyday lifecan not be used. 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.
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 roughsurface with a metallic luster. Among the ingredients are alkyds, epoxides, aluminum powder and acrylic. Hammer blends can be used for non-ferrous metals, and a primer before application can not be used. The first layer serves as a primer, while the second layer is anticorrosive. But the third one is used as enamel. It is impossible to protect the surfaces using hammer paints, which will be heated during operation above 150 ° С.
Anticorrosive paint for metal, applicationwhich should be carried out according to the instructions, is applied to the prepared surface. The substrate should be cleaned, degreased and dried, free from old layers of paint using emery or metal brushes. 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 will be the application of paint, whileit should be remembered that the temperature of the environment should vary within 20 ° C, while 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 the work, you can use a spray gun, wait between the layers for 15 minutes.
If you are interested in the question of whichthe property has paint for metal on rust grade ХВ-0278, then you should familiarize yourself with the information presented below. The spreading rate of the dried film is from 60 to 120 g / m2, 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 specifications 2313-174-21743165-2000.
According to users, long-term protection withUsing the composition of ХВ-0278 can be provided only if the metal structure does not contact with electrical solutions, capacitors and oxygen. The rusting center will be completely isolated after the application of the paint. As another advantage of the described primer enamel, there is no restriction on the area and form of processing. In addition, 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. This paint is easy to apply. You can do the work yourself. According to the buyers, the master must use personal protective equipment, ensuring intensive ventilation inside the premises.
The above-described paint for metal on rustanticorrosive, 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.
