Self-Healing Technology Explained: How TPU PPF Repairs Scratches

Activation Methods

Sunlight: Natural solar heat activates the repair process within minutes to hours

Hot Water: Pouring hot water (60C+) provides immediate repair

Heat Gun: Professional installers use heat guns for precise control.

Limitations of Self-Healing

Self-healing handles only minor surface scratches (below the topcoat depth)

Deep cuts penetrating the TPU base layer cannot self-repair

Performance varies by manufacturer and topcoat formulation quality.
