NOA148


UV-Curing Optical Adhesive NOA148

Overview:
Low-index (1.4740) UV adhesive for glass-to-glass bonding.
pic

NOA148 is a clear, colorless adhesive; recommended for glass-to-glass bonding with good adhesion to cellulose acetate butyrate (CAB). Cures at 315–395 nm UV; full cure: 6 J/cm². As a coating it shows oxygen inhibition; cure in an inert environment such as nitrogen to overcome it.
