Paint is the main part of the car that exudes its own charisma for the owner. Various treatments are carried out so that the paint color does not become dull easily, starting from just giving a layer of wax or doing the occasional body polish. If the condition is smooth, the car can even increase its own selling point. After the surface of the car is ready, the painting process can be carried out and this painting process is carried out in a vacuum room so that there are no foreign particles such as dust that will interfere with the painting process.
In the repainting process there are several painting processes that are carried out, namely primary painting (commonly called the foxy process), then the surfacer paint process (painting with NC or PU paint), then the top coat (commonly called the clear glossy/dof process).
Types of Car Paint
Before repainting a car, you must know the various basic materials that can be used to paint a car. You must know this so you don’t choose the wrong car paint. Next, you can leave the work to a mechanic or you can do it yourself.
Choose the car paint color you want. Avoid using original colors if you are still unsure about wearing them. Make sure you are comfortable with the color of your choice so you don’t have to work twice or so you don’t regret the color you have chosen.
The following is an overview of the various types of car paint for body repair.
1. Car Primer Base Paint
Primer primer serves to coat the body plate after it is sanded to prevent rust and increase or even out the adhesion between the base metal and the next coat of paint.
Primer base coat is an anti-corrosion paint which basically contains pigments which function to prevent corrosion or rust, combined with resin or binder or adhesive which has protective properties against iron or steel (steel) so that it is protected from external media, namely air and water.
The various types of primer primer are as follows:
Primary Wash
A one-component primer base coat containing nitrocellulose and alkyd resin. This type of primer is very easy to dry and easy to use, but its resistance to rust prevention and adhesion characteristics are not as good as other types of primer.
Primary Urethane
It is a two-component type primer that uses polysocyanate as a hardener. This primer paint is also called as Polyurethane paint. Uretane primer provides excellent rust resistance and adhesion characteristics. Polyurethane base paint contains high quality ingredients and the drying process is not as fast as acrylic paint, so it can produce an even paint surface and high gloss results. Polyurethane paint is easier to apply and uses extra slow polyurethane thinner.
Epoxy Primers
Epoxy Primer is a material to protect metal from the oxidation process and is water resistant. Epoxy primer is sprayed to coat the surface of the body plate with 1 to 2 layers of spraying to get maximum results. The characteristics of Epoxy Primer are that it protects well materials made of metal from rust and adheres very well to metal and produces a perfect base layer for painting.
2. Car Surface Paint
Surfacer is the second layer (coat) that is sprayed on top of the primer, putty or other base layer (under coat), Surface serves as a filler for small dents or paper scratches, preventing the absorption of the final paint (top coat) and leveling the adhesion between the base coat paints (under coat) with final painting (top coat).
The various surfaces are as follows:
Lacquer Surfacer
This one-component surface is made primarily of nitrocellulose and alkyd or acrylic resins. Lacquer Surfacer is easy to use and has fast-drying properties. However, in terms of coating characteristics, this material has a lower rate than other surfaces.
Urethane Surfacer
This two-component surface, which is mainly made of polyester, acrylic, and alkyd resin, is a two-component type surface that uses polyisocyanate as a hardener. While they provide excellent coating ability, they dry slowly, requiring forced drying at a temperature of approx. 60°c (140°F)
As is well understood, the faster the surface dries, the lower its coating ability (adhesion, filling ability, absorption/sealing resistance, water resistance), so Urethane Surfacer is a good type of surface.
Thermosetting Amino Alkyd Surfacer
This type of surface includes a two-component surface whose main ingredients are made of melamine and alkyd resin, which are used as primers before the use of bake-finish paints. Requires heating to temperatures of 90 to 120°C (190 to 240°F), but provides the same coating capability as a new car.
3. Top Coat (Clear Coat)
Top coat is the top coating process of car painting. Can also be referred to as the last layer that determines the result of painting whether to be glossy or matte. The last step in painting the car body and the last coating is clear coating. It is a colorless (clear) coating that enhances body color and protects other coatings from damage. If you don’t take care of the clear coating, it will have a bad effect on the color of your car.
Clear coat also contains anti-UV content so that UV rays do not penetrate the top coating. How well the clear coating resists UV light will affect the overall durability of the car paint. Some well-known clearcoat brands are Sikkens and Spieshecker.
This is a review of several types of car paint in body repair. You can take your car to the nearest car salon or car body repair shop for maximum car painting. Hope this information is useful for you.
