The coating process is the core of Paint Protection Film (PPF) performance, with two mainstream technologies: overlay coating and embedded coating. Overlay coating only attaches functional materials to the surface, leading to rapid performance decay, while embedded coating injects functional ingredients into the uncured TPU substrate at the molecular level, creating an integrated structure that has become the first choice for car owners pursuing long-term protection.
Embedded coating has three core technical advantages: First, the interlocking interpenetrating network structure makes the coating an inseparable part of the substrate, greatly improving wear and wash resistance; Second, the uniform distribution of functional molecules forms a "performance reserve", which continuously replenishes the worn surface and avoids cliff-like performance decline; Third, the dense and integrated protective layer effectively blocks corrosive contaminants such as bird droppings and acid rain, and enhances stain resistance.
In addition to superior technology, embedded coating PPF also brings multi-dimensional long-term value: the longer service life reduces the annual usage cost, the stable performance realizes hassle-free car ownership experience, and the effective protection of the original paint safeguards the vehicle's residual value. It also has core performance such as sunlight-driven scratch self-healing, durable water repellency and long-lasting mirror gloss.
The development of PPF is moving towards "integration and durability", and embedded coating is the optimal solution to solve the durability pain point of PPF at present. Choosing embedded coating PPF is a long-term investment in car paint protection, letting technology guard the beauty of the car for a long time.
