Norland Optical Adhesive 142

Norland Optical Adhesive 142 is clear liquid adhesive that will cure when exposed long wavelength ultraviolet light. NOA  142 is recommended for bonding for glass to glass. Adhesion is also good to cellulose acetate  butyrate. NOA 142 is cured  by ultraviolet light between 315 to 395 nm. Full cure requires 6 Joules/cm 2 . The adhesive exhibits oxygen inhibition when  used as a coating.  To overcomethis the adhesive must be cured

under an inert atmosphere, such as nitrogen.
