From a professional point of view, the paint surface maintenance film is currently made of TPU, PU, PVC, TPU and PU belong to polyurethane, but TPU belongs to thermoplastic polyurethane; PVC is simple, needless to say, mainly depends on hardness maintenance;
TPU material, there must be tough silk;
I summarized several 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 the top coating: polyurethane transparent film layer, elastic polymer for eliminating dust adhesion, contamination and surface scratches: The main function is an anti-fouling coating.
The second layer is a special polyurethane film, which has good toughness and can restore elasticity at any stretch. The main function of the first layer is to restore.
The third layer is a specially developed acrylic copolymer with strong adhesion and removability of paint: the main function is to remove no residue.
The fourth layer is the bottom film: the ground polyester anti-adhesion maintenance film, which is a layer of bottom maintenance film to be torn off during construction.
Guchi's invisible garment is made of TPU material.
Through the sense of smell to feel, if you smell a strong taste of chemicals, then this clarifies that the raw materials used by car clothes are inferior. A good car paint maintenance film should be tasteless or tasteless.
The brightness of a good film on the paint surface will be increased, especially for black car paint.
The marked pen with film can be wiped clean with a paper towel. If the membrane with poor performance is not able to achieve this effect.
A good film has good wear resistance and endurance. It can't be used in a perfect device or maintain your car. It can seriously reduce the appearance of the car.
Double-coated TPU (thermoplastic polyurethane elastomer rubber) has four layers of material. The film mask has good lubricity, which makes the liquid not easy to remain, thus avoiding the worry of acid rain and other liquid pollution when parking in the open air on 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 good paint maintenance film, the difference between uncoated and pasted film is obvious. The obvious wear marks before are completely covered, and the whole body looks fresh.
