Many motorists after some time think about painting the wheels of their car. Someone wants to give their vehicle an original look, someone thinks about protection from external influences on the metal, someone wants to combine both.
There are various types of paints, and many ways have been devised to coat them with metal. This allows you to choose the best option for each car. The painting of Naiad discs is very popular. This technology will be discussed later.
Naiad Company
Painting of disks in Moscow is carried out by Naiada. During its existence, the company has painted over 900,000 discs in 15 years. You can handle any type of disc: stamping, forged, cast.
The main profile of the company is a powder type of staining. A guarantee is provided for the work carried out for three years. This confirms that the coating does not crack, peel or change color.
You can choose any color in the RAL range. Perhaps coloring in several shades. To understand the benefits of powder coating, you need to consider the characteristics of existing methods of applying the compositions.
What can be painted?
Many vehicle owners are wondering how to paint car wheels? There are many varieties of formulations. They differ in composition, color, price and method of application.
Six basic types of paints are offered for metal products: epoxy, oil, alkyd, acrylic, hammer, powder. To make the right choice, you need to consider each of them.
Varieties of colors
Paint for painting discs can be made using various technologies. This determines its basic qualities. The following types of paints are available:
- Resin compounds. They have epoxy resins in their composition, have not received their wide distribution in everyday life due to very high toxicity. This type of paint coating creates a very strong and flexible film, which allows you to maintain properties even at high temperatures and aggressive environmental influences.
- Natural colors on drying oil. Designed for indoor use, as they absolutely cannot withstand sudden changes in temperature. The basis of this species are natural oils and drying oil. With prolonged exposure to the environment, it quickly fades.
- Perftolate (alkyd) enamels (PF). Due to its low cost, practicality and ease of application, alkyd paints (enamels) are most widely used. They have very good penetration, can be applied easily even with a brush or roller by hand, create a durable film that withstands almost any aggressive environmental effects (temperature difference, direct sunlight, water, etc.).
- Acrylate paints and varnishes. This type of paint has gained distribution recently. A characteristic feature of staining is the absence of a sharp unpleasant odor. Therefore, the painting can be done even indoors, without fear of getting severe poisoning.
- Hammer coatings. At the heart of this variety of coloring materials are epoxy, acrylic and alkyd components. To obtain the special properties of the resulting coating, particles of ground aluminum (powder) and fine glass were added to the composition. As a result of staining with such compositions, the upper layer acquires a rough layer with a characteristic metallic luster. These paints provide reliable surface protection against vibration, moisture, and temperature spikes.
The listed compositions have a lot of disadvantages, if applied to rims. For this reason, the Naiad company offers exclusively powder types of coloring.
Powder paints
Powder coating began to conquer the market quite recently. Due to the need for thorough surface preparation, as well as the possibility of applying only expensive professional equipment, this type of composition cannot be used at home.
An important feature of powders is the high saving during application, since particles that do not get onto the metal are collected by special devices and can be reused. Powder coating makes it possible to apply a film of 35 microns per layer, which is impossible when using other types of paints. The special durability of the coatings is guaranteed to its customers by Naiada.
Application Methods
In the process of processing metal surfaces, the question may arise, how to properly paint discs? There are several approaches. One of the easiest, but slow and costly methods is to paint manually with a brush or roller. It is mainly used for painting small products where other methods cannot be used.
Spraying with an air spray gun. In this way, it is possible to apply to the metal only paints that are sufficiently liquid (low viscosity). It is necessary to use a separate air compressor and a conventional household spray gun.
For small and very small products, dipping is used. The fastest and most convenient way that does not require additional devices.
Airless spraying is also used to apply paintwork to various metal surfaces. Advantages are the economical use of paint, the absence of a compressor with long hoses. Painting is carried out by a special spray gun with mechanical spraying. It is possible to use compositions of various densities.
The above methods have certain disadvantages. A more advanced technology in all respects is used by Naiad.
Features of staining in the company "Naiad"
Painting discs "Naiad" has a lot of advantages. This is one of the most high-tech ways. It uses one of the well-known laws of physics - the law of electrostatics.
A negative charge from a special power source is supplied to the rim, and the powder is positively charged in a special air atomizer. According to the law of electrostatics, positive charges are attracted to negative ones. So the powder is attracted to the surface of the rim and reliably held by the laws of physics.
Processing procedure
Powder coating takes place in a special chamber equipped with a system for recycling and reusing paint, as well as forced ventilation. When performing the procedure, the employee must use special means to protect the respiratory system and skin.
But before the stage of electrostatic powder deposition, rims must be prepared in a special way, which will ensure maximum durability of the coating and its resistance to external influences.
Rims are exposed to very strong environmental factors. This is water, various reagents, gravel, stones. As a result, rust, scratches and chips may appear on the discs. In order for the powder to adhere to the metal as well as possible, it must be processed in a certain way. Some car owners have a question: how to paint the wheels without removing the rubber? In this case, painting without dismantling will not work. This is a mandatory step in the procedure. Polymerization occurs under the influence of high temperature. The tires would simply melt.
Initially, the disk is processed with various acids and alkalis, abrasive materials. A sandblasting apparatus may be used . This removes a layer of old paint, aligning chips and dimples.
In order to ensure maximum adhesion of the powder to the metal of the disk, phosphate treatment is used. This stage can be called priming. Then the product is washed in order to remove residues of various substances. So there is a preparation for staining.
The final stage. Polymerization
After the wheels are prepared for painting, a powder coating layer is applied, the product should be heated at a temperature of 200-220 ° C. This is necessary in order for the powder to melt and form a continuous polymer layer.
Polymerization is carried out in special furnaces under the control of electronics. After the required warm-up time, the discs cool. It is by this technology that powder coating of disks is produced in Moscow, which the Naiad company is engaged in.
Materials and equipment
Special high-tech equipment is used by Nayada. Painting discs is a complex process. The leader in the production of powder coating equipment is the Swiss company ITW GEMA. This is the most modern, high-performance and high-quality equipment. It is used by the Naiad company when processing rims.
The manufacturers supplying paints are world famous companies Dupont, Pulver, AkzoNobel. The quality of these materials is confirmed by many positive reviews from motorists around the world.
Paint Prices
The cost of staining directly depends on such parameters as the diameter of the rim, type of rim, complexity of the pattern, type of staining, number of colors, as well as additional services for diamond grinding, preparation, etc. At Naiada, you can preliminarily find out how much it costs to paint the wheels by car. The price remains acceptable.
If it is alloy alloy or forged alloy wheels without electroplating, the minimum processing cost is from 5250 for a product with a diameter of 14 inches and up to 8360 rubles for a diameter of 21 inches (the price is indicated for all 4 wheels).
If there is any galvanic type coating on the discs (chrome plating), then the cost will be slightly higher. It ranges from 6400 to 9930 rubles. For conventional stampings, the cost is from 4200 to 6690 rubles per set. But you can find out a more accurate price only by calling the organization directly and talking to a consultant.
Powder Coating Reviews
The car enthusiasts who painted the Naiad wheels are mostly satisfied with the result. The coating is very resistant to various adverse environmental factors. Over the years, it does not fade, does not crack, and keeps excellent.
Shagreen powder coating hides chips and scratches on the disc metal. And the warranty period of three years is the best confirmation that this type of staining is the most technologically advanced and durable.
Having considered what features the Naiad disc painting is characterized by, its high quality and durability can be noted.
