Low Temperatures And Rapid Curable Adhesives Development Back Ground 1. Device structures change to small and complicated. ↓ UV irradiation is difficult to fully reach 2. Component materials: metal to plastic for cost reduction. ↓ Lower heat stability Customers need lower temp. and fast curable resin equivalent to UV adhesives. Characteristics 　- Cure Completed at 60℃×5min - Cure Completed at 80℃×3min Higher temperature enables faster curing speed. Fully cured at 120C x 10 sec
