Painting using new technology. Specifics of powder painting of a car Is powder coating on car paint possible?

Powder painting auto is one of the most advanced technologies, allowing for excellent results both visually and qualitatively. The composition of powder paint, in addition to microscopic polymer granules (which forms a film on the surface of the car), includes a pigment that determines its color, as well as special additives. It should be noted that the procedure in question can only be carried out in a paint booth, and this makes contacting a car service optimal solution for everyone who needs this service.

Powder painting of cars in Moscow: advantages and disadvantages

The experience of many metropolitan car enthusiasts shows that this technology has many more advantages than disadvantages. In particular, its advantages include:

painting speed;
high resistance to temperature changes (from -50 to +130 degrees);
strength and wear resistance (allowing manufacturers of such paints to provide a guarantee for them for up to 20 years);
possibility of use not only with metal, but also with plastic and glass coatings;
no need to use solvent and hardener during the painting process;
environmental Safety.

As for the disadvantages of powder painting, these are:

the need to create special conditions, as well as the availability of expensive tools to implement the task;
lack of possibility of collation;
limitation on the minimum thickness of paint application (at least 35 microns).

As you can see, the number of advantages of the method under consideration allows us to consider it an optimal solution for many different problems.

Powder painting of cars: price in Moscow and the moments that determine it

It would not be superfluous to list the factors that determine the cost of this service in many metropolitan car services. These include:

total amount of consumables used;
the level of complexity of the work performed, as well as the degree of urgency;
availability of additional services ordered by the client.

At the same time, it should be noted that today in Moscow there are a considerable number of car services that are capable of both high-quality and very inexpensive implementation of such a task as powder painting of cars. Price the price at which they evaluate their work is largely acceptable due to high competition in the market, making obviously expensive proposals practically useless to anyone.

Powder painting of cars is a new painting technology that allows you to obtain a high-quality polymer coating with minimum quantity losses and a high degree of security. The undeniable advantages of this method over traditional painting lead to its increasingly frequent use not only in the automotive industry, but also in other areas of industry.

Powder paint is based on the use of high-polymer powders consisting of polymer granules ranging in size from 10 to 100 microns.

What elements are included in powder paint?

In addition to the polymer that forms a film on the surface of the car, powder paint includes the following components:

color-determining pigment;
hardener;
filler that strengthens the film;
additives that regulate spreading and create structure.

A prerequisite for powder painting of cars is the presence of a machine equipped with special equipment. Of the usual equipment, the chamber must have air supply and filtration systems. Specialized equipment includes paint sprayers, a powder recovery system, and a polymerization oven.

Powder painting technology is based on the ability of magnetized powder granules to attach to car body elements. In this case, the powder is magnetized in advance and then sprayed in a thin layer onto the surface of the part. After this, the part is placed in a polymerization oven, where it is maintained at a temperature of 160 - 200 degrees for 10 - 20 minutes. Under such conditions, the powder melts and forms a continuous layer of paint.

Depending on the polymer used, paints are divided into thermoplastic and thermosetting. Thermoplastic paints fuse when heated without chemical transformation and form relatively weak coatings. For powder painting of cars, thermosetting paints are mainly used, in which, when heated, not only the fusion of polymer particles occurs, but also a chemical reaction between them. As a result, a durable film is formed that is resistant to physical and chemical damage.

The most important advantage of powder coating is the ability to reuse paint particles that were sprayed but did not end up on a car part.

The powder particles go through the stages of filtration, preparation and then are supplied again for application to the part. This method allows you to significantly save paint, reducing losses to 1 - 2 percent versus 50 - 60 percent when painting with liquid enamels.

Powder painting, like painting with liquid paints, requires preliminary thorough treatment of the car body. The preparation process includes the following stages:

Removing rust and oxides from metal parts of the car.
Degreasing of all parts and surfaces.
Coating a degreased surface with a layer of phosphate or chromate to increase the adhesion force of the powder to the surface.

Advantages and disadvantages of powder painting

In case of high-quality preparatory work, as well as compliance with powder painting technology, it is possible to obtain a very reliable paint coating.

Powder painting of cars can significantly reduce painting time due to the fact that the paint is applied in just one layer. The thickness of this layer can be adjusted within wide limits from 35 to 250 microns. By applying one uniform layer, the possibility of formation of

The painted surface can withstand shocks and temperature changes from -50 to +130ºС. Powder coating has less porosity compared to conventional paints, therefore it has greater anti-corrosion resistance;

Manufacturers of powder paints provide a coating guarantee of up to 20 years;

Currently, powder paint is used not only for painting metal parts of a car, but also plastic and glass products. It is used in painting car rims, bumpers, headlight reflectors, mirrors, as well as plastic parts inside the car. Using powder paint you can obtain not only a smooth finish, but also a matte, semi-matte finish, leather-like coating and other effects;

When using powder painting of cars, the need to use solvents and hardeners disappears. Paints are sold ready for use. This allows you to get rid of the process of selecting the degree of paint dilution. In addition, powder paint does not dry out during long-term storage;

The absence of flammable solvents in powder paint almost completely eliminates the possibility of a fire. The process of painting a car with powder paint is environmentally friendly.

Powder coating of cars also has disadvantages. Among them are the following:

Powder painting can only be done in a specially equipped room using complex and expensive equipment. This condition does not allow small and medium-sized companies to use the above-described painting method;

Powder paint cannot be painted on your own. Although this drawback is compensated by the huge number of colors and shades offered by various car cosmetics manufacturers;

There may be difficulties when applying paint to non-heat-resistant surfaces;

The minimum thickness of the paint layer is limited and is 35 microns.

The significant predominance of the advantages of powder painting of cars over the disadvantages contributes to the rapid growth of the popularity of this technology. The number of powder paint manufacturers, as well as companies offering powder painting methods, is constantly increasing. Production technologies are constantly being improved, which allows us to achieve the highest quality of car painting.

Having bought a brand new car, its owner expects that his shining appearance will remain for for a long time... In practice, unfortunately, everything turns out to be not so rosy. Constantly exposed to a number of influences during operation, body elements lose their appearance and need to be restored. In this case, powder painting of bumper and door moldings, mufflers, calipers and other important components that also determine the aesthetic characteristics of the car comes to the rescue.

She has whole line advantages and allows not only to improve the appearance of the vehicle, but also to create a polymer coating that will last for a long time. Thanks to it, the service life of the painted element will be significantly extended, and its appearance will be at its best!

What is powder painting of car parts? Why is it needed?

Powder painting is a special technology for applying powder paints to various elements of the car body, which allows you to obtain a polymer coating. The latter is characterized by excellent aesthetic and strength characteristics and allows you to extend the service life of the treated elements. This is very important when it comes to the car body. While driving, its parts are subject to impact, small pebbles hit them, which leads to chips and scratches. Frequent contact with moisture causes the development of metal corrosion processes, so over time, expensive restoration (or even replacement) of the element may be required.

Also worth mentioning are the chemical reagents that are used to remove snow and ice on roads in winter period time. They also contribute by having a destructive effect on the metal. Powder painting of the car muffler, its nozzle, calipers and other elements helps solve all these problems. Thanks to her they:

get effective protection from exposure to moisture, therefore corrosion processes do not develop on them;
high level of protection against mechanical and shock loads;
decent level of protection from the destructive effects of chemical reagents.

Thus, by spending money on powder painting, you will save much more on repairs and replacements.

We have already talked a lot about the advantages and features of painting a car with powder paint in previous articles, so today we would like to shed light on such an interesting point as spray booth, which is perhaps the most important element of the entire process.

A few words about the camera

In this chamber, a powder composition is sprayed onto the entire car or its individual part, after which the product undergoes polymerization in an oven. If we talk about the commercial and industrial use of the powder method, then spraying is usually carried out through electrostatic attraction. As for using powder paint at home, in this case any method can be used, including manual.

Now on the market you can find special chambers for powder coating for the purpose of mass production of small batches or single use. They usually consist of a chamber itself and a block along with filters necessary to clean the air from particles of the powder composition.

You can enter the machine into the painting chamber through a special opening, so during operation it will be completely inside the device. A remote control located behind the walls of the unit allows you to control the painting process.

Painting principle

Each painting chamber certainly includes two systems: paint recovery and air purification. The principle of operation is that the powder particles are magnetized, due to which they adhere tightly to the surface of the product due to the potential difference, thereby forming a uniform coating. After applying the powder, it is heated to a temperature of about 200 degrees and the product is kept in such conditions for about 20-30 minutes. The camera can be used not only for painting the body, but also when working with discs, calipers, bumpers, mufflers and other car components.

When buying a car, we want to preserve its original appearance as long as possible. After all, the paintwork of the body is constantly exposed to sand, crushed stone and gravel flying out from under the wheels of passing vehicles, falling or low-growing branches, unfavorable factors external environment. All this leads to the formation minor damage- chips, scratches and dents. This is why anti-gravel films that protect the surface of the body are so popular today. New technology for protecting the body using polymer powder painting will keep it in perfect condition for decades.

Polymer powder painting

Types of polymer paints for cars

The use of polymer powder coatings is the most modern and effective method protection of the car body. Polymer painting makes it invulnerable to external mechanical influences and the influence of aggressive environments, and maintains the perfect appearance of the car for a long time, giving the surface standard quality and high aesthetics.

Today there is a wide variety of polymer paints, which can be classified into types according to a variety of criteria. They are all divided into two large groups according to the principle of polymer layer formation:

thermosetting, which form a film on the surface of the metal as a result of a chemical reaction of molten powder particles;
thermoplastic paints, when applied, a diaper is formed without a chemical reaction, by fusing the particles.

Thermoplastic paint

Based on the type of substance that forms the film, polymer paint for a car can be:

polyamide;
polyester;
based on epoxy resins;
polyester-epoxy.

There are polymer- powder paints, with which you can give the surface of the car body a different texture:

glossy paints, ideal for even and smooth surfaces without the slightest flaws;
matte;
textured paints that well mask various defects on the metal of the body;
metallic effect paints;
polymer-powder coatings with moire effect.

Matt paint

By purpose they exist polymer paints the following types:

For interior and exterior use;
for protection against corrosion;
paints that create a chemically resistant surface;
electrical insulating paints;
antifriction polymer coatings;
decorative paints.

Polymer painting

The modern market can offer the widest selection of polymer car paint colors of any shade from the RAL palette, which expands the possibilities of creating a different exterior.

How is polymer powder painting of a car performed?

The technology of polymer powder painting includes several sequential stages:

Preparation of the surface, which must be thoroughly cleaned of paint and varnish, and then degreased with alcohol solutions. The best way cleaning is sandblasting, which will not only remove all old paint, but will also strengthen the top layer of metal. There should be no oxides or rust left on the surface.
Application of polymer powder paint using the electrostatic method, using a spray gun in the form of a special pistol-type device. Negatively charged powder, falling on the grounded surface of the car body, is held on it due to the potential difference. Devices for applying powder paint are equipped with a recovery system that captures powder that has not reached the part being painted and feeds it back to the receiving hopper. Therefore, paint consumption is very economical, and its loss is practically eliminated.
Heat treatment, for which the product to be painted is placed in a special oven called a polymerization chamber. Within 15-20 minutes at a temperature of 200 o C, the granules of the polymer composition applied to the surface of the body melt and turn into a viscous fluid mixture, forming a homogeneous layer, which, polymerizing, turns into a high-strength film.
The cooling process occurs naturally when the painted product is removed from the oven. At this stage, it is already possible to carry out any mechanical processing of the painted surfaces, for example, grinding or finishing edges.

Application of polymer powder paint

Before painting, you need to remove from the car all parts covering the body, as well as those elements that can be deformed under the influence of the operating temperature of the camera.

Advantages and disadvantages of polymer car painting

Among the advantages of applying polymer powder paint to a car body over other methods of painting it, it should be noted:

high durability of the coating, characterized by wear resistance, resistance to mechanical stress and the influence of adverse external factors, including chemical exposure to aggressive environments, such a coating does not scratch, does not peel off, and retains its aesthetic appearance for a long time;
economical use of paint, because the coating thickness is only 60-80 microns;
the safety of the painting process, since the powder does not contain any solvents or toxic substances;
significantly less time spent on painting and cooling the surface being painted than when using paints and varnishes; immediately after cooling, which occurs quite quickly, you can start using the car;
a wide selection of paint colors, and the ability to obtain a structured surface that well hides existing defects on the body;
high durability, the service life of the polymer powder coating is at least 20 years.

There are significantly fewer disadvantages of polymer metal painting than advantages, and the main ones are:

the ability to perform work only in workshop conditions, using special equipment;
the impossibility of tinting, that is, obtaining different shades by mixing different colors; ready-made powder paints from the manufacturer are used for painting;
limitation of the dimensions of the parts to be painted, depending on the size of the polarizing chamber;
applicability for coloring only heat-resistant materials;
It is difficult to eliminate painting defects; they cannot be eliminated locally, but require repainting the entire product.

Polymer painting is used not only for the car body, but also for other parts, for example, rims. This is the most reliable way today to protect your car from damage, give it an ideal appearance and extend the life of the metal elements of the car.
