01 What is the paint protection film ?
As its name suggests, invisible car cover is a translucent film affixed to the vehicle body that is generally referred to as the “paint protection film”. It is a new type of high-performance environmental protection film that has gained a great deal of popularity in the aftermarket for automobiles in recent years. Super-durable, strong extensible, anti-pollution, anti-yellowing, anti-scratch, and anti-bumping are characteristics of invisible automobile attire. After being fitted and adhered, they may isolate the original automobile paint from the air, prevent acid rain, UV rays, air pollution, insect carcasses, and bird droppings from deteriorating the paint surface, and simultaneously increase the glossiness of car paint.02 What is the material of car paint protection film?
02 What is the material of car paint protection film ?
Paint protective films have undergone four generations of material upgrades.
First generation :PU Polyurethane. Advantages : strong toughness; Disadvantages: poor weather resistance, irreparable scratches, poor resistance to alkaline corrosion, turning yellow.
Second generation: PVC Polyvinyl chloride, PVC .Advantages:hard material, strong impact resistance, low cost; Disadvantages: can not be wrapped, degumming serious, irreparable scratches, turning yellow.
Third generation :TPU Thermoplastic urethanes .Advantages: strong weather ability, strong toughness, good stretch ability, oil resistance, corrosion resistance and chemical resistance, recycling and environmental protection; Disadvantages:complex production process, low yield and high manufacturing cost.
Fourth generation :TOP COATED TPU Thermoplastic urethanes. Advantages:coatings with different properties are developed on TPU, which can customize invisible clothes with different high performance such as quick repair, corrosion resistance, yellowing resistance and stain resistance according to different requirements, and extend paint protection film with different visual effects; Disadvantages: complex production process, low yield and high manufacturing cost.
03 What are the functions of automobile paint protective film ?
The purpose of paint protection film is essentially the same as that of mobile phone film adhesion: to safeguard the original automobile paint. After multiple rounds of improvement, the paint protection film are now more functional.
Prevent small scraping, chemical corrosion, weather resistance, high-speed flying stones, acid rain resistance, yellowing resistance, paint aging, sun lines, micro-mark self-repair, hydrophobic self-cleaning, blocking ultraviolet rays, brightening car paint, etc. Of course, saving money is the most crucial factor. The cost of waxing, plating, and washing the vehicle annually spends several thousands. The value of the car will drop if it is repainted. You can quickly remedy these issues by installing paint protection film. When you tear off the tpu film in a few years, you will find that the vehicle is still brand-new, so even if the vehicle is rubbed slightly, you will not feel distressed.
04 Difference between aliphatic TPU and aromatic TPU ?
Compared with aromatic TPU, aliphatic TPU has no benzene ring and is not easy to turn yellow after long-term storage. Aromatics will slowly turn yellow as time goes by. If your car paint shows obvious yellowing within 2 years, it must be an aromatic TPU. How to determine whether the TPU ppf is aliphatic? In fact, it is judged according to the warranty time, among which the general warranty period is 7-10 years is aliphatic, and less than 5 years is aromatic. Remember this point so you can pick your paint protection film next time.
05 What is the coating process ?
There is essentially no big difference in the substrate of paint protection film, and the coating procedure has the highest scientific and technological content. The various coating techniques adopted by various manufacturers dictate the various comprehensive performances of various types of invisible paint film. Shark anti-pollution bionic coating PPF have strong pollution resistance, oil resistance, and corrosion resistance. Platinum coated PPF have strong scratch resistance and weak repair. PPF with nano hydrophobic coating have good hydrophobic effect, strong self-repairing ability, and easy cleaning. The key is that the owner chooses the paint protection film that suits his own vehicle and what performance he needs, to choose the one that best suits his own vehicle.
06 Why the scratches of the paint protection films can be repaired ?
TPU is a thermoplastic elastic polymer.The material’s molecular structure is organized and uniformly dispersed, and it possesses excellent fluidity. When subjected to external force or heat, the molecular flow gradually returns to its original state, leaving no trace and retaining its integrity.
07 Why paint protection films improve the brightness of car paint ?
High transparency is a property of paint protection films, and the film’s surface is as reflective as silk and has the texture of silk. Installing ppf can effectively enhance the dull state of paint surface, and under sunlight, the mirror effect of film surface becomes more apparent, which increases the glossiness of paint surface by 30% and prolongs its brilliance.
08 How long is the service life of paint protection films ?
The paint protection films made of aliphatic TPU can be used for up to 10 years, but that made of aromatic TPU will appear yellow after 2 years.
09 Do you need to take care of it frequently after installing paint protection films ?
We need to take care of the paint protection film, and if conditions permit, we’d better go to the maintenance shop once a month to take care of it with professional maintenance products. And wash the car after rainy days to avoid acid rain stains remaining on the film surface.
10 How to replace the paint protection film if they are scratched ?
General brands will give A4-sized film scraping and replacement service, and car owners can go to the store to replace it with a certain installation cost.
11 When is the best time to install paint protection film ?
It’s best to install it immediately after picking up the car.The new driver too easily scratched his new car; If you don’t install it on your new car in time, you will regret it after being scratched.
12 Is it necessary to install paint protection film when the car has scratches ?
If you don’t mind scratching, you can do not install it, or you should install it as soon as possible to avoid scratching.
