What Is Paint Protection Film and How Does It Work?

Nowadays, more and more modern car owners not only pay attention to the performance and appearance of their cars, but also place great emphasis on the long-term protection of the car paint. During daily driving, factors such as flying sand and stones, branches scraping, and car washing scratches can all cause irreversible damage to the original factory car paint. To address these potential threats, a high-performance transparent film material called "PPF (Paint Protection Film)" has been introduced. But what is paint protection film? How does it protect the car paint? Is it suitable for all vehicles? Is it worth investing in? This article will introduce you systematically to the working principle, target users and selection suggestions of PPF, helping you make a wise decision and keep your car looking brand new for a long time.

What is Paint Protection Film (PPF)?

Automobile paint protection film (PPF) is a highly transparent film made of thermoplastic polyurethane (TPU). It is mainly applied to be adhered onto the car paint surface, serving to resist scratches, corrosion and minor impacts. PPF boasts excellent elasticity, wear resistance and corrosion resistance. Additionally, it usually has a "self-repairing" feature, meaning that when a minor scratch occurs, it can automatically recover to its original state after being exposed to sunlight or heated, keeping the paint surface shiny and new.

PPF was originally developed by the US military. However, with the advancement of materials technology, this technology has gradually become an excellent protective coating for vehicle surfaces. Nowadays, PPF is entering the mass market at more affordable prices and with a wider range of options, becoming the preferred choice for car owners who are concerned about protecting their vehicles.

What are the differences between PPF and traditional car paint protection methods?

Many car owners have chosen methods such as applying sealant, coating or quartz coating to protect the car paint. However, these methods fall under the category of "chemical coatings", which mostly rely on the chemical components to bond with the paint surface. Their durability is limited and they cannot withstand obvious physical damage. In contrast, PPF is a "physical protective layer" that can directly absorb minor impacts and scratches, and has stronger impact resistance and durability.

Common Professional Terms Explanation

• TPU (Thermoplastic Polyurethane): Currently, it is the mainstream PPF substrate, featuring flexibility, durability, and excellent self-healing properties. It is a hallmark of high-quality PPF.
• TPE (Thermoplastic Elastomer): An early-used material, it has good elasticity but inferior self-healing and transparency compared to TPU.
• PET Film: Used to protect the PPF adhesive layer and surface coating. It can be removed before installation without affecting the performance of the film itself.
• VLT (Visible Light Transmittance): Reflects the transparency of PPF. The higher the value, the clearer it is, and the less it affects the car paint color.

When there are minor scratches or brush marks on the surface of the film, simply exposing it to sunlight or heating with hot air can automatically restore its smoothness, without the need for manual repair, effectively prolonging the appearance of the car paint as new.

High transparency or optional colors

Veintone offers high-gloss transparent films as well as a variety of matte, metallic, and iridescent color options, catering to different vehicle models and individual user needs. The high-gloss models are almost "invisible" and seamlessly adhere to the vehicle, without affecting the original paint texture; the color film series achieves a win-win situation of appearance customization and protection.

Anti-ultraviolet and anti-yellowing

By adding UV-resistant stabilizers and weather-resistant resins, Veintone Film effectively blocks up to 99% of ultraviolet radiation. It can effectively prevent the aging and fading of car paint, and the film body itself is not prone to yellowing or cracking. Even in high-temperature or strong sunlight conditions, it can maintain its clarity as before.

Anti-corrosion, impact-resistant to gravel

During daily driving, the car paint often faces threats such as impact from flying stones, corrosion by insect corpses, and acid erosion from bird droppings. The Veintone PPF has a high-strength elastic protective layer that can withstand mild physical impacts and chemical corrosion. Rreducing permanent damage to the original paint caused by scratches and corrosion.

Improving Vehicle Resale Value: Used Cars Easier to Sell at Good Prices

Vehicles equipped with Veintone paint surface protection film maintain a good paint condition even after long-term use. In the second-hand market, the cleanliness of the appearance is an important factor in determining the price. PPF has become an effective way to increase the vehicle's residual value and enhance its resale competitiveness.

Easy to clean, reducing the frequency of waxing

The Veintone PPF model features a low surface energy coating, creating a similar "lotus leaf effect", which enables easy anti-fouling and waterproofing.

Therefore, the installation of PPF is more suitable to be handled by professional technicians to ensure that the performance of the film material is maximized.

Professional construction environment requirements

High-quality PPF installation requires the following construction environmental conditions to be met:

• Dust-free environment: Preventing fine dust particles in the air from entering the membrane during construction to avoid blistering or a gritty texture.
• Constant temperature control (22~28°C): Stable temperature helps enhance the extensibility and uniformity of the membrane material, especially for self-healing coatings which are sensitive to temperature.
• Professional tools: Tools such as water spray guns, scrapers, hot air guns, membrane cutting knives, and positioning lights can improve construction accuracy and reduce membrane material loss. The 20one certification construction center is equipped with standardized dust-free construction rooms and a professional technical team, ensuring that the effect of each film is consistent.

Installation Steps Overview

The installation process of PPF generally involves the following steps:

1. Thorough surface cleaning: Remove residues such as asphalt, water stains, flaking paint, and oil films to ensure the base surface is clean and free of impurities.
2. Pre-cutting the film material: Use data templates or manual cutting based on the vehicle model outline to ensure a proper fit.
3. Spraying positioning liquid: Spray the special positioning liquid between the vehicle paint and the film material to assist in the sliding positioning of the film.
4. Scraping and draining the film: Use a scraper to remove water and bubbles from beneath the film, ensuring a seamless adhesion.
5. Heating and shaping: Heat the corner areas with a hot air gun to help the film material adhere better and activate the self-repair layer. The entire construction process must be meticulous and continuous, avoiding excessive stretching and misalignment.

How long does the installation process take?

The installation time for full window film covering on a mid-sized car is generally 1 to 3 days, depending on the complexity of the vehicle model and the scope of the project (full vehicle or partial). Professional installation does not require extensive vehicle disassembly. Usually, only small accessories such as door handles, rearview mirrors, or lights need to be removed to ensure a more secure and aesthetically pleasing edge treatment.

During the installation process, Veintone Film strictly adhered to the "minimum disassembly principle", minimizing interference with the vehicle structure while ensuring the effectiveness of the film application.

 

Common Misunderstandings of PPF and User Q&A

Will PPF affect the color of the car paint?

No. High-quality PPF (such as Veintone Film) uses a highly transparent TPU base material, which hardly affects the original color and luster of the car paint. Some brands also offer matte, metallic, and color-changing personalized film models, which not only protect but also enhance the appearance. In the case of transparent films, the original car color can be presented 100%, and due to the smooth surface of the film, the luster is even enhanced.

Can PPF be applied to the entire vehicle? Is partial application effective?

PPF can provide full vehicle protection as well as local protection for specific areas, such as the front bumper, hood, rearview mirror, and door handles, which are prone to frequent scratches.

• Full vehicle film application offers comprehensive protection and is suitable for high-end or new car users.
• Partial film application has a lower cost and provides targeted protection with strong practicality.

Twentyone Film offers multiple trimming options to meet the needs of different car owners.

Can PPF and car paint crystal coating be used simultaneously?

In principle, it is not recommended to apply car paint crystal coating before applying PPF film. The silicon-based coating formed on the surface of the crystal coating will affect the adhesion of the film, resulting in poor adhesion or edge peeling.

Recommended Correct Order:

1. If the surface has already been coated with a crystal layer, it is recommended to polish and remove the coating before applying the film.
2. If a PPF film has already been applied, a special coating treatment can be carried out on the film surface to enhance its hydrophobicity and anti-fouling properties (a special film surface crystalizing agent is required).

How long is the service life? Is it prone to falling off?

The PPF made of high-end TPU material (such as Veintone Film) can have a normal service life of 5 to 10 years, which is related to the climate, usage habits and maintenance. Under professional construction conditions, the PPF bonding is stable and does not bubble or have edges or corners that lift off. The Veintone product uses imported pressure-sensitive adhesive layers and multiple coating structures, which have strong weather resistance. It can remain securely attached even in high-temperature or rainy and snowy environments for a long time.

Will the original vehicle paint be damaged after the removal?

As long as you use high-quality PPF products under professional conditions, normal removal will not damage the car paint. Veintone Film employs an environmentally friendly adhesive system. It can be completely peeled off after heating, leaving no residue of adhesive or paint. However, if the original vehicle has undergone paint restoration or used inferior coatings, there may be a risk of paint peeling during the removal process. Therefore, it is recommended:

• Use brand-name genuine products
• Installation and removal are carried out by professional technicians
• Regular maintenance to prevent water ingress at the edges or aging

FAQ

① Is PPF better than crystal coating?

PPF (Paint Protection Film) and crystal coating are two different types of vehicle paint protection methods. PPF is an actual film that has stronger capabilities in resisting scratches, preventing stone strikes, and resisting corrosion. It is suitable for car owners who seek long-term physical protection. On the other hand, crystal coating is a chemical coating that mainly enhances the gloss of the paint and provides a certain level of anti-fouling effect. However, its protective strength and service life are not as good as PPF. If you have a sufficient budget, it is recommended to choose PPF first, or apply crystal coating after applying the film to enhance the surface effect.

② How long can the PPF be used on the vehicle?

High-quality TPU material PPF, such as the Veintone series, has an average lifespan of 5 to 10 years, depending on the brand, film thickness, construction quality and usage environment. Proper installation, regular cleaning and avoiding the use of strong acid and alkali cleaning agents can effectively extend its protective effect.

③ Can the PPF dismantle itself?

Theoretically, the owner can remove the PPF by themselves. However, if the operation is not done properly, it may cause damage to the original car paint or leave adhesive marks. It is recommended to slowly peel it off under moderate temperature conditions with the help of hot air, and use professional degreasing agents to clean the remaining adhesive. If you are not sure about the operation method, it is best to have it handled by a professional installation store.

④ Will the PPF turn yellow or develop edges?

Low-quality PVC material membranes or inferior TPU membranes are prone to yellowing and peeling due to ultraviolet radiation and air pollution. High-quality brands such as Veintone use anti-UV nano-coatings, which effectively prevent yellowing and pass the weathering tests. Under standard construction, they can maintain clarity and adhesion for a long time.

⑤ How to carry out daily maintenance after installing PPF?

After applying the film, it is recommended to avoid washing the car within 72 hours. It is also suggested to clean the car regularly every month using neutral car wash solution and avoid using solvent-based cleaners. The film surface can be lightly waxed or coated to enhance its hydrophobic property, but avoid polishing treatments of the type that involves grinding. Proper maintenance can significantly extend the protection effect and appearance.
