Norland Optical Adhesive 1665

Norland Optical Adhesive 1665 is a yellow tinted liquid adhesive that will cure to a clear film when exposed to long wave ultraviolet and/or visible light. NOA 1665 is recommended for bonding glass to glass. Adhesion is
also good to CAB, polycarbonate and other plastics. The adhesive when fully cured is very rigid and brittle.  NOA 1665 can be cured with ultraviolet light from 315nm to 395nm. Peak absorption is 365nm. It can also be cured with visible light from 400nm to 450nm. Full cure requires 6 Joules/cm2. If used as a coating or exposed to air the adhesive will need to be cured under a nitrogen atmosphere to prevent the surface from remaining tacky due to oxygen inhibition
