Norland Optical Adhesive 148

 

  Norland Optical Adhesive 148 is clear liquid adhesive that will cure when exposed long wavelength ultraviolet light. NOA148 is recommended for bonding for glass to glass. Adhesion is also good to cellulose acetate

  butyrate. NOA 148 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 overcome this the adhesive must be cured

  under an inert atmosphere, such as nitrogen.
