11. 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
