Painting discs with powder paint: testimonials. Powder painting of discs with their own hands
In-demand service in automotive environmentwas the restoration of the appearance of the wheels. Painting cast discs with powder paint is in great demand and is the best way to return the car to its former form.
A reliable and modern method of surface restoration
Restoration of the physical state of cast discs involved in a lot of SRT.Videos and advertising are found at almost every step. Difficulties can arise with the final part of the process, as well as with bringing the disc to its original form.
Powder painting discs today has little to no competition. This modern technology successfully combines with moderate cost and excellent results.
Myths about the complexity of the process
For many, the disc painting technology seemscomplex and conjures up a picture of a documented process with exact volumes of materials, people in special clothes, the use of modern equipment.
But in fact everything is not as scary and difficult asthis may seem at first glance. But the problem is that the powder coating of the discs is impossible in the garage. Technology requires the presence of a whole complex, the price of which is quite high.
Advantages of dyeing powders
The process is very simple and economical, of course, if you use professional equipment. For painting only a small amount of material is sufficient.
Powder paint is distinguished by a largedurability and good resistance to mechanical damage. These coatings retain their shade and texture for a long time. Also among the advantages are a wide range of colors.
In numerous car service centers, powder painting of cast discs is carried out with the help of special equipment.Professional technology implies the presence of a special pistol with electrostatic effect. Using it, the dye is applied to the metal surface of the disc.
Then the processed products are sent to the chamberwith a high temperature for baking. The composition is polymerized and the paint becomes homogeneous. Before applying powder to the surface of the disc, the disc is thoroughly cleaned and then ground.
After polymerization, the layer is varnishedincrease the strength and durability of the surface, as well as to consolidate the result. When the procedure is performed at home, this method is not used, although the work stages remain the same.
Features of self-painting
The fact that the dyeing procedure in a garage andon SRT is different, does not mean that the end result will be worse. Powder painting discs with their own hands is not only an opportunity to save money, but also a way to improve skills.
Despite the advantages of using powder dyes, it is recommended to use acrylic analogs for independent work.But the algorithm does not change. Only other tools will be needed. However, motorists agree that the process of painting discs with a powder does not justify itself, if you do work in the garage.
Paints: types, brands, colors
For work with wheel disks, the following materials are used:
- epoxy - have increased resistance to alkalis and acids;
- Polyester - withstand the effects of the atmosphere and have a high resistance to corrosion;
- polyurethane - withstand abrasion, oils and solvents;
- Silicone - persistently withstand high temperatures.
The modern market offers products from differentmanufacturers. Among them are Pulverit, P-EP-45, Bishon, RADAR and other compounds. All products allow you to very accurately pick up the necessary colors, choose the texture, type of structure. It can be moire, antique, shagreen. The most common range of colors is prescribed in the standard RAL. However, the market offers other options.
Some consider this preparatory stage notso important and neglected by him. This is in vain. If you do not give enough strength, time and attention to grouting seams, removing old paintwork, flushing dirt and oil stains, it will be difficult to get a high-quality result, which gives powder painting of discs. Preparation involves several important steps. This treatment with abrasive tools and chemicals, etching, phosphating, drying and washing.
In the process of abrasive and chemical preparation, there will not be any work that can not be done independently.At this stage, scale, rust, oldpaint. Also, if necessary, the surface of the disk is leveled. For this, you can use both a different hand tool and a sandblaster. In the process of chemical cleaning, alkali or acid can be used.
By etching from the surface, remove those contaminants that did not disappear after the first stage of work.These are oxides and rust. They are easily cleaned with solutions of strong acids. This work requires special care.
The phosphating process involves processingiron, chromium or manganese. Chromic anhydride is also used. By phosphating, the adhesion of the paint to the surface increases. After all the preparatory steps, it is necessary to thoroughly wash and dry the product. After that, the disk is ready for painting.
It is not necessary, but still desirable. Priming compounds will help the disc to acquire resistance to corrosion, and also increase adhesion. Often used for primers are epoxy materials.
How to apply
The technology requires equipment. This is not done in the garage. The process itself is performed in a special chamber using a special atomizer. It operates by electrostatic principle. Thus, charged particles of a powder under the influence of compressed air fall on a surface that has a neutral charge. The powder is retained on the surface due to electrostatic attraction. Then the disk with the put powder goes to the chamber for baking and polymerization.
With your hands, you can only apply aerosol paint to the disc from the can, for everything else you need equipment.And it is quite expensive, and buy it foronce or twice there is no point. How much does it cost to powder the discs? 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 the workshop.
This process takes place in an oven with an electronicmanagement. This is the only thing that distinguishes these devices from conventional dryers. The temperature regime for the melting of the paint is from 190 to 220 degrees. Electronics accurately monitors temperature conditions and time. After that, the disk is cooled.
Powder coating of discs: reviews
Car owners have already appreciated this staining technology. The result exceeds all expectations.According to car owners, the surface hashigh resistance to damage, bright color, can be matte or glossy. It is the high resistance to wear making this technology so popular. What many do not like is the impossibility of repeating the process in the garage.
If the discs lost their aesthetic appearance,Powder painting of discs will help restore their previous state. Feedback from those who have already used the service is a direct confirmation of this. Comments of people who applied to SRT, only positive.
