After buying a new car, many of my friends like to put a film on the glass of the new car. Indeed, after affixing a high-quality glass film on the windows, it not only can insulate heat, protect the sun, but also protect the privacy of the car. However, due to the lack of understanding of the automotive glass film, some consumers could not tell whether the film was good or bad and bought inferior glass films. So how to choose high quality genuine automotive glass film? Today we talk about it.
â— Harm of inferior glass film
Everybody gives automotive glass film because the glass film can have the effect of isolating solar infrared (insulation), ultraviolet (sun), and privacy protection. Inferior glass film not only does not provide heat insulation, sun protection, but also causes Other bad effects. For example: fade, blistering, and so on.
In addition to the fading and blistering of poor quality glass membranes, due to the limited production costs, the residual solvent used in the adhesive layer contains benzene, formaldehyde and other substances. After being exposed to the sun, the emitted gas will cause the health of the people inside the vehicle. Harmful, serious or even cancer. Therefore, using this glass film is not as good as no film.
â— How to distinguish between genuine and inferior films
First of all, let's talk about one of my real experiences. Once a friend of mine posted a car three times in three years. The first time was a gift from a 4S shop when you just bought a car, and it faded after being posted in a 4S shop. . In desperation to go to Auto City for a set of glass film known as genuine 3M, but this film just after a year, it began to blistering, but also exudes a particularly pungent taste. Finally, with the help of his colleagues, he found a brand authorized store. Although he bought a genuine film, the high price actually made him hurt for a long time.
So as an ordinary consumer, how do we identify genuine automotive glass films and inferior films? How can I buy a genuine glass film at a lower price? Don't worry, we have summed up some of our experiences in selecting and buying glass films for everyone.
1. Look at brands and channels
When choosing a car glass film, what brand and price to choose is one of the issues that consumers are most concerned about. In terms of price, there are many brands of glass film on the market, and there is a big gap in price. Therefore, looking at the price alone is not enough to judge whether the glass film is good or bad.
1 4S shop sales/gift glass film
I believe that the film on many friends' cars is a “big gift†when they buy a car at the 4S shop. Indeed, it’s a convenient thing to do decoration when you buy a car, and you get such a gift when you buy a car. Consumers are relatively good at purchasing feelings.
However, in the 4S shop film is the perfect choice? It can't be so sure. Although some glass films sold in 4S stores are genuine, the price will be relatively high, and the given glass film may not guarantee quality. After all, buying a car now depends on a substantial discount to the price, so pre-sales decoration and after-sales maintenance have become a source of income that cannot be ignored. Therefore, the price of the glass film sold in the 4S store is higher than that on the market. 3 times is also a common thing.
2 Auto glass sales film
Nowadays, there are many merchants selling auto glass film on the market, especially the mixed auto parts city. What are their purchasing channels? We have no way to verify it, and if our consumers don't have experience or professional equipment, they can't completely distinguish between genuine and counterfeit goods. product. Therefore, in the Auto Parts City to buy glass film, it is easy to encounter counterfeit products.
3 Authorized shops and e-commerce
In the wide variety of automotive glass film brands, there are many large brands of product quality is relatively guaranteed, such as: Johnson (Johnson Johnson), 3M, Wei solid, Long film and other brands, are brand-name products in this field. In their official website, you can find the addresses of authorized domestic brand stores in various cities. In these authorized stores to purchase glass film, although the price is more expensive, you can rarely buy counterfeit products.
Some friends may ask, do not buy glass film in 4S shop or Auto City, but do not want to spend too much money to authorize the store to buy, how to do it? In fact, we can also buy in some reliable online e-commerce providers, such as car homes and other e-commerce providers. From time to time, we will launch some preferential activities to ensure product quality, and prices will not be as expensive as authorized stores. My one A colleague recently bought a set of 3M full-glass films from e-commerce companies, which cost only 600 yuan. It can be said to be very cheap. However, this kind of e-commerce group purchase activity has a time limit and can only wait until the electricity supplier engages in activities. If you can't wait and want to buy a genuine glass film, you can only go to the authorized store to purchase it.
2. Regular warranty card and warranty period
Authentic glass membranes purchased from regular sources come with a warranty card. Some brands have customer feedback on the warranty card. Everyone can send scraps of the glass film on their car, plus the warranty card number and other information to the manufacturer. The manufacturer will help. Identify whether we purchased genuine products.
Of course, the identification of authenticity through the warranty card can only be done in a formal authorized store or e-commerce provider. If it is purchased by a non-authorized merchant, the warranty card they provide may also be false. Therefore, the most important thing before we purchase the glass film is to look at the authorized qualifications of the business, and then look at the warranty card so that it will be more reliable.
3. Thermal insulation experiment
In addition to the above methods of judging from the purchasing channels and prices, I have also collected some "earth methods". The insulation experiment is one kind. In many stores selling automotive glass film, some red iodine lamps are placed to simulate the infrared heat radiation in the sunlight. We can use these tungsten lamps to test the purchased glass film.
The test method is very simple. Place your hand in front of the iodine tungsten lamp. The glass film is placed between the hand and the iodine tungsten lamp. If the hand can feel the heat of the iodine tungsten lamp, it can be judged that the heat insulation effect of the glass film is not ideal. However, this method is only a very simple method of identification and can only identify some inferior glass films.
4. Smell, hard to distinguish by hand
This way of smelling is also a very simple method of identification, but it can only target some particularly inferior glass films. Authentic glass film uses pressure-sensitive adhesive, and basically has no taste, and some particularly inferior glass films, due to lower production costs, the glue used contains benzene, formaldehyde and other substances, tear the glass film carefully smell, will smell The pungent taste of this glass film suggests that everyone should not buy it.
Some other friends may ask whether it is possible to distinguish authentic glass films by hand. In fact, this method is not referenced, because no matter what kind of glass film, it is difficult to distinguish between good and bad on the handle, even if the film shop workers, can not distinguish from the feel of the true and false glass film, so we It is not recommended that you use this method to identify.
â— Summary:
When choosing the automotive glass film, many of our friends were fooled by the flicker of the business because of the limited ability of our consumers to identify. The method introduced today for everyone is summarized as follows: Friends who are not afraid to spend money can choose to purchase from formal authorized stores; those who do not want to spend more and want to buy genuine friends can choose group purchases or other preferential policies of e-commerce. In short, if you want to buy a reliable glass film, you must buy it through reliable channels.
