Japanese cars than German cars wagon thin?

   The thickness of the paint on the issue, basically a mainstream understanding is: Japanese cars than German cars to be thin. But then in-depth to ask, after all, how thin is thin, thick thick, how much is considered a reasonable range? I am afraid that most people do not have much of this concept, today, like brother talk with everyone about the car paint thing.

Answer in the Japanese car is better than the Department of German cars before the paint thin, it is better to look at the common market in Japan and the Department of German car paint thickness level.

        From the above data, most of the Japanese car paint is indeed thin than the Department of German paint, Japanese car paint thickness is generally about 100 ~ 110um, while the German car paint in the 150um or so. However, everything is not absolute, like the blue bird in the table, the car paint thickness can be snapped to play Sagitar's face. Therefore, different positioning models, even with the same manufacturers, the thickness of the paint is not the same, can not be generalized about the Japanese car paint thin. Then by um (micron) to calculate the thickness of the paint, in the end affect the performance of the vehicle which? The following take a look.

The composition of the paint

        In order to make us more aware of the impact of car paint thickness, first of all to understand its type and structure.

There are three types of paint:

Car paint in the traditional coating process is divided into four layers, common to the body plays a protective and aesthetic features, let's elaborate on the name and role of each layer of paint。

    Electrophoresis layer: attached directly to the white body, the body has anti-corrosion protection, and for the coating to provide a good adhesion environment.

    In the coating: attached to the electrophoretic layer, anti-ultraviolet, to protect the electrophoretic layer, and to enhance the corrosion protection of the body for the paint layer to provide a good adhesion environment, some manufacturers in the coating can also play a certain color hue Set off role.

    Paint layer: attached to the coating, to further enhance the body's anti-corrosion protection, and display hue, we see a variety of colors is the paint layer displayed.

    Varnish layer: attached to the paint layer, and further strengthen the body's anti-corrosion protection, and protect the paint layer from the small scratch, the color is more translucent, slow down the fade phenomenon.

Thin paint is jerry-building?

    If it is the same taste, the same formula, that thin paint is absolutely jerry-building. But in fact, the whole still need to see the final performance, nothing less than the impact of paint and material (thickness). Normally, the traditional paint is a four-layer structure, which has a coating process, the thickness of about 40 microns, the biggest role in coating is to prevent electrophoresis (ED) coating due to ultraviolet radiation and powder.

    With the development of materials technology, paint coating formulations have been optimized, has been able to achieve the effect of coating, so the new process is basically cut off this process, which means that paint thickness is reduced. In fact, this proposition is similar to the lightweight, in general: by upgrading the material or structure to achieve the same performance results, this should be progress, rather than cut corners.

Thickness of the paint with scratch-resistant degree of it?

Car owners are worried that the car will not be scratched, in fact, with the overall thickness of the paint is not much relationship, because the main protective effect of only the varnish layer. In fact, the most important factor in scratch resistance is the hardness of the paint, the hardness index depends on the paint layer in the "clear coating", which is the outermost layer.

    Paint film hardness is the standard for testing the hardness of paint. For the current GB hardness requirements for not less than H. A simple test method is to pencil sharpener into a round head, hand-held pencil and the measured paint film into a fixed angle of 45 degrees, to the pencil to impose 1kg under pressure, move forward 1cm. After erasing the pencil with an eraser, check whether the film is scratched. If there is no scratch, the hardness of the paint to meet the H level.

    Currently most of the paint on the market for the hardness of the basic level of H, but also some car enterprises with 2H, 3H the hardness of the two levels of varnish, like Beijing-Benz is the hardness of the varnish varnish is 3H.

    In fact, Xinjiang brother suggested that for most consumers, the car is just a tool used in the election when the car is not necessary too concerned about the thickness of paint, the normal scratch is also very normal, no need to be too heart , Or else the heart will be very tired.

    Finally give you a car owners advice, paint is an absolute one-time items, after the damage, post-perfect repair will leave any difficult to make up the defects, color must be there (of course, most people may be difficult to distinguish) Non-compliance, fade uniformity is absolutely inconsistent, impact resistance, etc. is definitely unqualified. Therefore, either to be careful driving, do not knock do not touch; either relaxed state of mind, calm treatment.
