Demanded service in the automotive environment has become the restoration of the appearance of the wheels. Powder coating alloy wheels is in high demand and is the best way to restore your car to its former glory.

Reliable and modern surface restoration method

Restoration of the physical condition of alloy wheels is carried out by many service stations.

Videos and advertisements are found at almost every turn. Difficulties may arise with the final part of the process, as well as with bringing the disc to its original form.

Powder coating of rims today has almost no competition. This modern technology is successfully combined with moderate cost and excellent results.

Myths about process complexity

For many, the technology of painting discs seems complicated and conjures up a picture of a documented process with exact amounts of materials, people in special clothes, the use of modern equipment.

But in fact, everything is not as scary and difficult as it might seem at firstsight. But the problem is that powder coating wheels is not possible in the garage. The technology requires a whole complex, the price of which is quite high.

Benefits of Powder Coloring

The process is very simple and quite economical, of course, if professional equipment is used. Only a small amount of material is needed for dyeing.

Powder paint has great durability and good resistance to mechanical damage. These coatings keep their shade and texture for a long time. Also among the advantages are a wide palette of colors.

Features

In numerous car services, powder coating of alloy wheels is carried out using special equipment.

Professional technology involves a special gun with an electrostatic effect. With it, the dye is applied to the metal surface of the disc.

Then the processed products are sent to the high temperature oven for baking. In this case, the composition polymerizes, and the paint becomes homogeneous. Before powder is applied to the surface of the disc, the disc is thoroughly cleaned and then primed.

After polymerization, the layer is varnished to increase the strength and durability of the surface, as well as to fix the result. When the procedure is performed at home, this method is not used, although the work steps remain the same.

Features of self-painting

What is the staining procedure under the conditionsgarage and service station is different, does not mean that the end result will be worse. Do-it-yourself powder coating of rims is not only an opportunity to save money, but also a way to improve your skills.

Despite the advantages of using powder dyes, it is recommended to use acrylic counterparts for independent work.

But the algorithm doesn't change. You just need other tools. However, motorists agree that the process of powder coating disks will not justify itself if you do the work in the garage.

Paints: types, brands, colors

To work with rims, the following materials are used:

• epoxy - have increased resistance to alkalis and acids;
• polyester - weatherproof and highly resistant to corrosion;
• polyurethane - withstand abrasion, oils and solvents;
• silicone - resistant to high temperatures.

The modern market offers products from different manufacturers. Among them are Pulverit, P-EP-45, Bishon, RADAR and other compounds. All products allow you to very accurately select the necessary colors, choose the texture, type of structure. It can be moire, antique, shagreen. The most common gamut of colors is prescribed in the RAL standard. However, the market offers other options.

Preparatory work

Some people think this preparatory step is not so important and neglect it. It's in vain. If you don't put enough effort into it,time and attention to grouting, removing old paintwork, washing off dirt and oil stains, it will be difficult to get the high-quality result that powder coating of rims gives. Preparation includes several important steps. These are abrasives and chemicals, pickling, phosphating, drying and rinsing.

There will be no work in the process of abrasive and chemical preparation that you could not do yourself.

At this stage scale, rust, old paint are removed. Also, if necessary, the surface of the disc is leveled. To do this, you can use both various hand tools and a sandblaster. Alkali or acid can be used in the chemical cleaning process.

By etching, those impurities that have not disappeared after the first stage of work are removed from the surface.

These are oxides and rust. They are easily removed with strong acid solutions. This work requires special care.

The phosphating process involves the processing of iron, chromium or manganese. Chromic anhydride is also used. With the help of phosphating, the adhesion of the paint to the surface is increased. After all the preparatory steps, it is necessary to thoroughly rinse and dry the product. After that, the disc is ready for painting.

Primer coat

It is not required, but still desirable. Priming compositions will help the disc acquire resistance to corrosion, as well asincrease adhesion. Epoxy materials are often used for primers.

How to apply

Technology requires equipment. This can no longer be done in the garage. The process itself is carried out in a special chamber using a special sprayer. It operates on the electrostatic principle. Thus, charged powder particles under the influence of compressed air fall on a surface that has a neutral charge. The powder is held on the surface by electrostatic attraction. Then the disk with the applied powder is sent to the baking and curing chamber.

With your own hands, you can only apply aerosol paint from a spray can to the disc, for everything else you need equipment.

And it is quite expensive, and there is no point in buying it once or twice. How much does powder coating cost? The price of 3-5 thousand rubles is more than affordable, and the result is high-quality and durable. When buying the whole complex of equipment for this process, painting will be much more expensive than in a service station.

Polymerization

This process takes place in an electronically controlled oven. This is the only difference between these devices and conventional dryers. The temperature regime for reflowing paint is from 190 to 220 degrees. Electronics clearly monitors the temperature and time. The disk then cools down.

Car owners have already appreciated this painting technology. The result exceeds all expectations.

According to car owners, the surface is highly resistant to damage, has a bright color, can be matte or glossy. It is the high wear resistance that makes this technology so popular. What many do not like is the inability to repeat the process in the garage.

If the discs have lost their aesthetic appearance, powder coating of the discs will help restore them to their previous state. Feedback from those who have already used the service is a direct confirmation of this. The comments of people who applied to the service station are only positive.
