1. Product Overview
tesa® 4720 is a 100µm transparent double-sided PET filmic tape with a differential acrylic adhesive system. The open side offers high adhesion for secure bonding across multiple substrates, while the covered side provides lower adhesion for clean, residue-free removability. It combines good tensile strength with controlled performance under various environmental conditions.
2. Applications
Mounting of LCD panels
Assembly of backlight units in electronic devices
