7.5 mil thickness series

The 7.5-mil thickness series serves as the foundational entry-level product in DCL automotive window films, featuring a thickness of 7.5 mils (approximately 0.19 mm) and the most affordable price point. The total film application cost typically ranges between ¥2,500 and ¥6,000, making it the top choice for car owners seeking optimal value for money.

Material Properties and Protective Performance

The 7.5-mil thickness series employs high-quality TPU (thermoplastic polyurethane) substrate, offering excellent physical properties and chemical stability. This thickness is meticulously formulated with coating materials to ensure a smooth surface and superior scratch resistance. The series features hydrophobic and stain-resistant properties, effectively resisting daily stains and scratches while possessing self-healing capabilities that automatically repair minor scratches, maintaining the vehicle paint in optimal condition. In terms of protection, the 7.5-mm car coating withstands everyday dents and meets the paint protection requirements for 30,000 kilometers of high-speed driving; tests demonstrate its ability to endure impacts from stones smaller than 5 mm.

From a practical application perspective, the 7.5-millimeter-thickness series demonstrates stable resistance to yellowing, with minimal coating shrinkage at temperatures above 20°C, making it suitable for use in southern regions. It offers a light transmittance of ≥90% and UV resistance of ≥98%, effectively enhancing vehicle gloss by approximately 5%–20%. The application process is relatively straightforward, requiring less technical expertise from technicians compared to thicker series, and is suitable for most film application stores.
