What are the functions of paint protection film?
1 Answers
Paint protection film serves the following four main purposes: 1. Enhancing vehicle gloss: The film can increase the glossiness of the car's paint by 5%-20%. Its transparent glossy coating effectively improves the paint's resistance to UV aging, preventing discoloration or yellowing. 2. Protection against corrosion and scratches: Since car paint is constantly exposed to the elements, it inevitably faces oxidation from the air and corrosion from rain, especially acid rain. Additionally, daily hazards like flying gravel and scratches from branches are unavoidable. The paint protection film acts as a transparent protective layer, isolating the paint from the external environment and providing effective protection. 3. Self-healing elasticity: Made from TPU (thermoplastic polyurethane), the film features elastic memory that allows it to automatically repair minor scratches. This means small scrapes and scratches can heal on their own, eliminating the need to file insurance claims for minor damage. However, it's important to note that the self-healing capability depends on the depth of the scratch and the usage environment; deeper or more severe damage may not self-repair. 4. Value retention: When selling a used car, repainted vehicles often receive lower valuations. Paint protection film perfectly preserves the original factory paint while enhancing its shine, thereby maintaining the car's value over time.
