1. Definition & Process
Traditional Top Coating
Traditional top coating is a mature surface coating technology applied to the surface of TPU film. It forms a protective layer on the surface through coating, curing and compounding, with stable process and reliable performance.
Immersion Coating
Immersion coating is an advanced infiltration coating technology. The TPU film is fully immersed in a functional coating solution to achieve three dimensional penetration and integration, bringing higher durability and consistency.
2. Advantages of Traditional Top Coating
- Mature and stable production process, high consistency and good yield.
- Excellent surface smoothness, gloss and hydrophobic effect.
- Good stain resistance and easy daily cleaning.
- Moderate thickness, good flexibility and easy construction.
- Cost-effective, suitable for most daily car use scenarios.
3. Advantages of Immersion Coating
- Full infiltration inside and outside the TPU, more uniform performance.
- Higher durability, longer functional life such as anti-yellowing and anti-stain.
- Better stretchability, not easy to crack when wrapping complex curves.
- Stronger resistance to hydrolysis, acid rain and chemical corrosion.
- More stable self-healing performance and long-lasting gloss.
4. Summary & Application Suggestions
- Traditional Top Coatingprovides reliable surface protection with mature technology, good appearance and cost-effective performance, which is suitable for daily urban use.
- Immersion Coatingprovides long lasting, high strength protection with better durability, stretch and anti aging performance, suitable for long term car protection needs.
