Introduction

Norland Optical Adhesive 139 is clear liquid adhesive that will cure when exposed long wavelength ultraviolet light. NOA 139 is recommended for bonding for glass to glass. Adhesion is also good to cellulose acetate butyrate.  NOA 139 is cured by ultraviolet or visible light between 315 to 450 nm. Full cure requires 6 Joules/cm 2 . The adhesive exhibits oxygen inhibition when used as a coating.  To overcome this the adhesive must be cured under an inert atmosphere, such as nitrogen.
