Why is "car paint" white prone to yellowing?

As the darling of car paint, white is almost every manufacturer every year to publish the top of the popular color trend survey, in daily life, an average of four cars have a white, the most intuitive thing happened around me - Chengdu road 90% of the cars are white! But the white car compared to other cars have a fatal disadvantage is that the body will gradually turn yellow over time, so what is the reason? Is there any way to solve it? Lead us into the white world today!
the color difference between the white car paint color difference is more obvious?
fact: it's just white pearls!
cars running on the road, occasionally scratching is very normal, especially when the larger accident, it is necessary to repair paint, but
compared with other color paint, white coverage is relatively weak, the primer requirements are higher, spray thickness also has very strict standards,
of which especially with white pearl spraying is the most difficult; White pearls, that's one of them!
Unlike other white paint, as a metallic paint, white pearls add metal particles, which makes it more difficult to mix and spray
than ordinary plain paint
the white car paint must be yellow for a long time?
fact: proper maintenance can properly delay the yellowing time!
001 weather changes and daily maintenance situation is not in place,
sunlight, ultraviolet radiation is the main culprit of paint oxidation, coupled with the air pollution, such as exhaust gas, dust, rain cement slurry, etc., are in contact with the surface of the car, speed up color paint oxidation
;
Resolving: car wash, reduce the chance of sun exposure, can park indoor garage do not stop in the open air, and
in the vehicle or a brand new state, you can wax, glaze and other beauty treatment, reduce the opportunity for direct contact between car paint and air
Why are large repair shops, 4S stores
chains so expensive? That's because he uses the highest-end products, has the most complete process, never thought to rely on stealing materials to achieve the purpose of profitability

the white body is particularly susceptible to dirt?
fact: just because it's more conspicuous!
The probability of all vehicles contaminated with stolen goods is the same, but white with the naked eye looks more obvious than it is, champagne, green, silver in the industry is recognized as a good way to take care of, the reason is
simply not obvious;
The result is that the soot dust mixture is innified with a small black spot, firmly attached to the body,
ordinary car wash process can not completely remove this small black spot;
solution: wash with tar cleaner or to a professional beauty shop treatment!
002: Parking near the site is just a construction site, or there are decoration projects in the process; decoration paint, dust and other easy to get on the body;
solution: away from here, if there is a common car wash can not handle, go to the beauty shop polishing waxing!
003 water mark: the appearance of this dark spot, because after rain failed to wash the car in time, coupled with the body originally has oil,
dust, will form vertical downward water marks, air conditioning outside the machine drop water also has a similar effect

As long as pay attention to maintenance, car wash, after the accident to choose professional store repair, white car is not terrible, take a little more time you will find that he is as beautiful as other colors, there is summer to pay special attention to prevent sun exposure, white paint relative weather resistance is worse, long burstwords easy to yellow
