6 ways to teach you how to identify good or bad invisible auto paint protection film

With the continuous development of paint protection products, invisible auto paint protection film has become a kind of car paint protection product with the best effect at present. However, because of its wide popularity, there are various types of invisible auto paint protection film products made of TPU material on the market, and the quality is uneven.

The core of the invisible auto paint protection film made of TPU lies in its durability and transparency. The high-quality TPU material can prevent damage to the car paint caused by gravel, sand, bugs and other objects on the road, while maintaining the clarity and gloss of the paint surface. Lower-quality TPU invisible auto paint protection film may cause adverse conditions such as increased oxidation time, insufficient reflection, and wrinkling, which will cause the car paint to age, discolor or even lose its protective effect. This requires us to have an in-depth understanding of the invisible auto paint protection film made of TPU and identify the advantages and disadvantages.

The three most important factors affecting the process of invisible auto paint protection film materials are material, coating and glue layer.

01, Judge by smell

Smelling the smell is a simple way to distinguish good and bad glue layers! First cut a piece of invisible auto paint protection film scraps, tear off the film; nose close, smell the smell.

A good invisible auto paint protection film should not be pungent, and it can even be said to be odorless. Some inferior invisible auto paint protection films will produce a pungent smell, which usually means that the material contains low-quality glue or other chemicals, which may cause damage to the paint surface or affect the protective effect, and also cause discomfort. Odor and health risks.

02 , Judging by the viscosity

In addition to the material and viscosity, the adhesion strength of the invisible car coating adhesive layer is also an important item to judge its quality. The following is a simple test method: Take a small piece of auto paint protection film, tear off the auto paint protection film and stick the machine cover, use the paint cover, and repeat the tearing and pasting 3 times, no glue residue, stable adhesion and no influence on the film.

In this case, it should be noted that if the back glue of the auto paint protection film is easy to detach, similar problems may also occur on the base material and adhesive layer of the auto paint protection film during long-term use. This means that when we want to tear off the auto paint protection film, the adhesive may remain on the surface of the car, leaving the car covered with residual glue.

03, Judged by toughness

From the perspective of the material of the invisible auto paint protection film, the advanced invisible auto paint protection film is TPU (thermoplastic polyurethane) material-environmentally friendly and recyclable. The toughness of high-quality auto paint protection film is generally excellent. If you accidentally rub the surface of the auto paint protection film, don't worry, it has a good automatic repair function. At the same time, the ductility of the auto paint protection film is also very good, and it can show the ideal state according to the curvature of the car body, while the defective auto paint protection film cannot achieve such a good effect. A simple test method can be used to judge the toughness of the invisible auto paint protection film:

1. First, take a small piece of auto paint protection film material with a length of about 10 cm and a width of about 3 cm;

2. Tear off the auto paint protection film, hold both ends, and pull hard in two directions;

3. Judge the toughness of the product according to the difficulty of stretching. If it can be easily broken, it means that the invisible auto paint protection film does not have enough toughness and does not have the ability to effectively protect the car paint. At the same time, when the hand is withdrawn, it will quickly retract and recover.

04, Fine coating

The coating of the invisible auto paint protection film is a key component that endows it with multiple magical functions, such as self-healing, water repellency, high temperature protection, anti-corrosion, etc. Therefore, choosing a good coating is also very important. The quality of the coating can be judged by a simple test method:

1. First, cut a small piece of leftover material;

2. Slowly pull the material toward both ends;

3. Observe the texture or texture changes in the middle.

If the texture on the surface of the material is very rough, it means that the coating of the invisible auto paint protection film is rough, not smooth, and does not have good quality. In contrast, a good coating should exhibit a fine, smooth texture.

05, Scratch repair

Scratch repair is one of the important selling points of invisible cauto paint protection film. For some minor scratches or collisions, invisible auto paint protection film can be automatically repaired to maintain the beauty of the car body. A simple test method can be used to judge the effect of scratch repair:

1. First, cut a small piece of auto paint protection film surface material and fix it on the test paint surface;

2. Use a steel brush to make multiple scratches along the same direction, pay attention to the number and intensity of scratches;

3. Observe whether the coating can repair itself.

In the test of using a steel brush to draw circles on the auto paint protection film surface for more than 100 circles, if all thermal repair/self-repair can still be maintained, use hot water or hot air at about 70°C for repair or self-repair paint at room temperature (about 25°C) It can be self-healed in 30 minutes; then such an invisible auto paint protection film has a good scratch repair effect.

Through the above test methods, you can have a preliminary understanding of the scratch repair effect of invisible auto paint protection film, and choose high-quality invisible auto paint protection film.

06, Original factory warranty

In view of the long service life of the auto paint protection film outdoors, the selected auto paint protection film brand must have reliable product quality and a complete after-sales service system. When we buy auto paint protection film, we have to consider whether the auto paint protection film brand comes from a company with manufacturer qualifications, rich experience and professional auto paint protection film production, which is also very important.
