1. UV-Curable PSA film is exposed to UV light 2. Photoinitator molecules in the adhesive absorb photons→ crosslinking reaction 3. Advantages of UV-cured hot melt PSA 4. Benefits of hot melt coating: 100% solids, environmentally friendly, small manufacturing footprint 5. Benefits of crosslinked acrylic: high cohesion / heat resistance, good aging and chemical resistance
