The natural surface of metalliccar disks with time loses its original appearance, loses aesthetic qualities and can be destroyed without proper care. The special coating helps to eliminate such processes. Manufacturers of auto chemical products offer paint and varnish compositions, liquid rubber and powder materials for such tasks, which make it possible to extend the life of the wheel base and give it a more attractive appearance. The technology of painting car disks has its own peculiarities and nuances of implementation, which should be taken into account.
To traditional means of painting discs, you caninclude acrylic blends and enamels. Their main advantages are to create a spectacular view, affordability and ease of application. With regard to performance, then, according to the manufacturers, both enamel and acrylic provide reliable protection against corrosion and mechanical damage. But the duration of this barrier is low, so in the near future it will be necessary to update it. More modern materials are represented by powder paint for metal and liquid rubber.
To begin with, it is worth noting their common features.First of all, it is high cost, durability of the layer and aesthetic appeal. And the greatest spectrum of protective properties is provided by the powder composition. If the rubber coating is predominantly designed to resist shocks, the powder exhibits resistance to aggressive chemical media. This is the optimal solution if you want to paint cast discs, but for the stamped it is better to prefer the same enamel or acrylic.
Work begins with the removal of the previous layer of paint,if any. This operation is carried out with strong abrasives. For example, in a short time, the surface can be removed from the old coating with a sandblaster connected to the compressor. Sand particles not only destroy the old base, but also provide an equalizing effect. In order to paint a new car disc with a uniform layer, it is necessary to degrease the cleaned surface. To do this, use special solvents for metals of a certain group, that is, the choice of chemistry depends on the type of disc.
This operation is not always required, but ifis calculated on the long-term operation of acrylic, enamel or lacquer coatings, then it should be done. On the surface degreased with solvent, a primer coat is applied over the metal. Again, special compounds for external processing of automotive parts are selected. The work is carried out with the help of a spray gun or other type of atomizer, which will allow a qualitative and even distribution of the composition. If you plan to paint cast discs, you should apply several layers (between the approaches a small pause is maintained). After the final layer, leave the surface to dry. By the way, this process can be speeded up with a construction hair dryer or a heat gun. But experts still recommend to dry discs in natural conditions, which will provide a more solid structure of the lower layers of the primer.
Traditional paintwork should beApply as well as a primer, using sprayers. The paint or enamel itself is previously diluted in accordance with the instructions. In the composition, it is desirable to add a little solvent. Next, the master's task will be to completely cover with a new layer of previously applied primer. It should not be visible under a layer of paint. It is important to emphasize that the painting of the wheel disks of the car must be carried out in special gloves, a respirator and glasses. Depending on the model of the sprayer, the tool can form a cloud of fine paint particles that fall into both the eyes and the respiratory system. With regard to the number of layers, depending on the type of primer and paint used, it may take from 3 to 5 approaches. Again, a full masking of the grounding base and a rich texture of the new composition will become an indicator of sufficient thickness.
As a basis, it is recommended to usecompositions of large manufacturers, which are few. Quality liquid rubber is produced under the brands Rubber Paint, Mibenco and Color Dip. Preparation is carried out according to the above scheme with degreasing. Next, you should carefully limit the area of painting with tape and cardboard inserts between the metal surface and the tire.
Direct painting of car disks with liquidrubber is carried out with the help of spray cans, in which the material base is supplied. In the process of processing it must be taken into account that the spray is held at a 60-90-degree angle relative to the surface to be painted. After that, the tape with the cardboard is removed, and the disk is left to dry, which can take from several hours to a day.
The most complex painting technology, whichrequires the use of special equipment. This is due to the fact that powder paint for metal can form high-strength coatings on a substrate only at high temperature. In other words, the process of baking paint on the surface must be organized.
The disc is placed in a special chamber-oven, inWith the help of compressed air and an electrostatic atomizer, streams with particles of polymer powder are directed onto it. They are attracted to the surface and are distributed uniformly over it under the action of electrostatics. The temperature regime varies from 120 to 150 ° C. The complexity of the process is compensated by a decent result. With the polymerization furnace, local painting of the car's discs is carried out, which ensures a dense, reliable and aesthetically original appearance of the product.
The choice of this or that method of registration of wheelsdepends on many factors. As experts recommend, it is necessary to start from the price group of the disk itself. For cheap models it is better to limit oneself to traditional means. The usual enamel or acrylic composition will be the best choice for forged or stamped products. But for expensive light-alloy modifications, painting of car disks on the basis of a powder or liquid rubber is more likely. The choice between these two methods is determined by the nature of the operation of the machine. A universal solution in terms of protection will be polymer powder. Liquid rubber is good with mechanical protection features and a spectacular matte design.
