In the process of car use, bump and bump are inevitable, but then there is a headache. First, it affects the use of the car. (The strength of the back painting on sheet metal is not as strong as before. The original car paint comes out at the high temperature of two hundred in the paint baking room, which can not be finished by any merchant outside. In addition, in the face of domestic climate problems, haze, acid rain, bird droppings under trees, resin and so on.
For this reason, the trend is that there are many kinds of invisible garments on the market, and they are well known. But the membrane is bad. How can we identify it?
From a professional point of view, the paint surface maintenance film is currently made of TPU, PU and PVC, TPU-PU belongs to polyurethane, once TPU belongs to thermoplastic polyurethane, and PVC is simple, depending mainly on hardness maintenance.
TPU material, there must be tough silk;
I sum up a few ways of identifying TPU. People in rivers and lakes have to learn two ways:
Pull hard until tough filaments appear, and then pour hot water upward, it will recover (mentioned above that TPU is a thermoplastic polyurethane);
CONSTRUCTION: The first layer is top coating: polyurethane transparent film, elastic polymer for dust removal and surface scratch contamination: The main function is an anti-fouling coating.
The second layer is a special polyurethane film, which has good toughness and resilience. The main function of the first layer is repairing.
The third layer is a specially developed acrylic copolymer, which has a strong adhesion to the paint surface and strong removability. Its main function is to remove some residual glue.
The fourth layer is the bottom film: ground polyester anti-adhesion maintenance film, which is a layer of bottom maintenance film to be torn off during construction.
Jinan automobile paint protective film
By smelling, if you smell a strong taste of chemicals, then this clarifies that the raw material used in a car is poor. A car paint maintenance film should be tasteless or pungent.
The brightness of each film will be increased when VS is not applied on the coated surface, especially for the black car paint.
The marked pen with film can be wiped clean with a paper towel. If the film with good performance can achieve this effect.
Double-coated TPU (thermoplastic polyurethane elastomer rubber) has one layer of material and good lubrication on the film mask, which makes the liquid easy to remain, thus avoiding the worry of acid rain and other liquid pollution when parking in the open air in rainy days.
7. Cover up the original scratches in car paint
Vehicles that have been used for a period of time, especially those with black or dark paint, will have a lot of obvious dazzling lines in the center of the hood, but after putting on a paint maintenance film, the difference between the non-film and the film is obvious. The obvious wear marks before are completely covered up, and the whole body looks fresh.
These are the basic methods for judging Jinan automobile paint protective film, which can be concluded by stopping Judging according to these conditions at the time of purchasing automobile clothes. Of course, if conditions permit, or advocate the choice of the right brand, but also believe in the principle of a penny for a penny.
