What Are Vehicle Wraps?

Auto tint film is a thin film object pasted on the front and rear windshield, side window glass and sunroof of the vehicle, and this layer of thin film object is also called solar film or heat insulation film.

Car film

Auto tint film is before and after the vehicle

Overall, there are 7 major benefits of automotive glass film:

1. Thermal insulation and sun protection . The film can block a lot of heat generated by infrared rays.

2, separated from ultraviolet rays . Medium and long waves in ultraviolet can penetrate very thick

With the rapid development of China's economic construction and the general improvement of people's living standards, automobiles are moving into families of ordinary people at an unprecedented pace. In particular, after China's successful entry into the WTO, auto prices have gradually decreased significantly, which has even stimulated the consumption of private cars in China. According to experts' predictions, in the next few years, China s car ownership will increase at a rate of 20% per year, and the huge aftermarket of auto aftermarket. The automotive film market in China will become a huge gold industry.

It has only been more than ten years since China's auto film market really formed, and the market is quite chaotic. In summary, there are several main manifestations of the chaos in the automotive film market:

First, the purchase channels are chaotic, and there are a large number of small businesses and small workshops. "

Visible light transmittance: The percentage of visible light (380-780) that passes through the glass / glass window film composite layer.

Visible light reflectance: The percentage of visible light (380-780) reflected by the glass / glass window film composite layer.

Solar transmittance: Percentage of solar energy transmitted through the glass / glass window film composite layer.

Ultraviolet light blocking rate: The percentage of ultraviolet light (280-400) reflected by the glass / glass window film composite layer.

Solar reflectance: The percentage of solar energy reflected by the glass / film composite layer.

Solar energy absorption rate: The percentage of solar energy absorbed by the glass / film composite layer. The absorbed solar energy can be radiated to both sides of the glass / film composite layer at the same time. The side with a high air velocity will radiate more energy.

Total solar transmittance: the sum of the portion of solar energy that passes through the glass / glass window film composite layer and the absorbed solar energy that is radiated to the interior. The measure of thermal insulation rate is the heat per square foot per hour (BTU / Hr. / Ft.2, where 1BTU = 262 calories). The heat insulation rate of transparent glass is generally 20 BTU / Hr. / Ft.2.

Total solar reflectance: the thermal insulation rate, which is the sum of the part of solar energy reflected by the glass / glass window film composite layer and the absorbed solar energy radiated to the outside.

Shielding factor: The total solar transmittance of the glass / glass window film composite layer relative to the glass.

U value: The temperature difference between the inside and the outside per hour per hour, the amount of heat radiation per square foot.

Performance requirements vary depending on the application. In general, the main indicators are visible light transmittance, visible light reflectance, heat insulation rate, and UV blocking rate.

There are three divisions and seven divisions in the industry. Specifically, there are the following standards:

Is the material correct

The front windshield crease does not exceed 1 (including one), and the position is generally at the corner (not more than 10CM from the edge); the rear windshield crease does not exceed one (including one); (Not more than 2CM off the edge), no more than one side crease (including one), no creases are allowed within the effective range of the wiper. Sitting in the driver's seat, there is no blurring or chromatic aberration when looking at the scenery outside the car through the front gear.

All the glass after filming must not have blisters, and the water must be scraped off (observe clearly from the left and right sides of the glass respectively).

The film at the upper end of the side window is cut straight, and the side window glass cannot rise to the top to prevent light leakage; the two sides of the side window glass must not leak light (the film is outside the rubber strip; there is light leakage through the light leakage); The maximum distance does not exceed 1MM.

The maximum distance between the film and the black ceramic dots on the edge of the glass should not exceed 2MM when the front and rear stops are attached;

The glass at the film must not have obvious scratches.

Side window rubber strips must not have new scratches.

Check the full load of glass film 1 meter away from the car within 10cm of the local area, and the number of dust points cannot exceed 10.

Due to the multiple metal layers of individual metal films, metal false marks may appear when the film is baked, but the location is generally not allowed in the middle of the edge (within 15CM from the edge).

Foil is a high-risk service item. Due to the technical level or glass defects, there is a possibility of glass breakage. The glass breakage occurs in the film or within 24 hours after the film is applied. The store is responsible for replacement.

The water used in the film must be filtered or precipitated.

2. The film generally needs a closed and dust-free environment.

3. Wool clothes or clothes with cotton wool are not suitable for wearing stickers, because cotton wool or wool on the clothes will be attracted to the paper by static electricity.

4. When the transparent paper is not disassembled, it must be washed or sprayed with water on the surface to prevent dust and sand.

The first generation of automotive solar film is commonly known as "dyed film". Usually, the dye is impregnated on a layer of polyester film to achieve the effect of absorbing visible light. This solar film is easy to apply and has good light shielding, but has poor thermal insulation effect, is easy to fade and degumming, and has a low service life.

The second generation is a metal reflective film, and some people call it function, and the heat insulation function has also been improved, but when the light transmission is high, the heat insulation is low and the light transmission is low. However, the metal plating layer may be oxidized, resulting in appearance problems and reduced thermal insulation performance, and the metal plating layer shields electromagnetic signals, affecting the use of navigation and other equipment in the car.

The third generation is the "Intelligent Spectrum Selective Film". Magnetron sputtering metal to increase the thermal insulation performance of the film, or to achieve the function of spectral selection through multilayer optical film technology, is the representative of the world's highest film-forming technology. It has extremely high heat insulation effect, which can effectively reduce the temperature inside the car and improve the efficiency of air conditioning. It can also prevent the debris from splashing when the glass of the car is broken, and avoid accidental injury to the passengers. Can block up to 99% of ultraviolet rays, can ensure that passengers are protected from ultraviolet rays. The multilayer optical film does not use metal plating, avoids oxidation problems, and does not shield electromagnetic signals.

1: After the car is pasted, avoid lifting the window for three days;

2: Do not wash the car within three days;

3: Vehicles with a sunroof during the three days should not open the sunroof during driving, especially at high speed;

4: After filming in winter, it is recommended that you do not lift the windows or wash the car within a week. It takes about a month for the front and rear blocks to dry out.

5: If there is foaming at the edge of the film, it should be repaired at the construction site within 24 hours. After the time is exceeded, the glue around the foam has dried up and the periphery of the film can no longer be moved, and creases will definitely occur during processing.

6: It is forbidden to stick strong adhesive labels directly to the film within one month after the film is attached, so as not to cause the film to partially detach from the glass.

7: Car foils must also understand the inspection policies of various cities. For example, in some cities, the front window and the glass outside the window are used for the driver's viewing area, and the visible light penetration ratio is less than 70%, and the annual inspection will not pass. When the car film is pasted, the triangular area left in the front window cannot be filmed, otherwise it will affect the normal annual inspection of the vehicle.

1. Do not lift the window within 3 days after the film is applied

2. Do not clean the insulation film and turn on the defogging line switch within one week after the film is pasted.

3. Do not clean the surface of the membrane with a solution containing alcohol or ammonia

4. Do not use sharp objects to pull the edge of the film away

5. If bubbles appear after filming, they must be handled at the construction store within 24 hours.

6. Don't let the air conditioner blow against the film, so as to avoid violent thermal expansion and contraction. ^[4-5]

7. The expiration date of the film should be handled with care. The shelf life of high-quality film is usually 5 years. After the expiration date, the owner should be careful not to dispose of it on its own. For the American film on the market, it is relatively easy to remove the glue without damaging your glass, ensuring that you will still be dazzling when you apply the film again.

8. Small information about requesting a warranty card No matter where you apply the film, you must pay attention to requesting a quality assurance card.
