Transparent polyurethane film with self-healing in the TPU layer
BRIGHT Clear is the brand’s flagship, premium transparent PPF film, designed to effectively protect paintwork from chips, scratches and abrasion. It self-heals minor scratches under heat, and its advanced hydrophobic coating makes it easier to keep the car clean.
| Layer | Thickness | Description |
|---|---|---|
| Top liner (protective PET) | 56 µm (2.2 mil) | A protective PET layer that shields the film's surface during storage and transport. Removed before application. |
| Top Coat (hardening coating) | 13 µm (0.5 mil) | A durable coating with self-healing and hydrophobic properties. Protects against UV radiation and makes cleaning easier. |
| TPU (polyurethane) | 152 µm (6.0 mil) | The main protective layer made of transparent, yellowing-resistant TPU. Provides flexibility and mechanical protection. |
| Adhesive layer (PSA) | 28 µm (1.1 mil) | A paint-safe, transparent pressure-activated acrylic PSA adhesive. Makes application and repositioning easier. |
| Bottom liner (protective) | 76 µm (3.0 mil) | A carrier film protecting the adhesive layer. Removed immediately before application. |
