The NOA-1625S UV-curing adhesive is clear liquid adhesive that will cure when exposed long wavelength ultraviolet light. NOA 1625 is recommended for bonding for glass to glass. Adhesion is also good to cellulose acetate butyrate. NOA 1625 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.

Keep NOA-1625S in a cool(5-22 ° C) dark place. If refrigerated, allow the adhesive to come to room temperature before using. Available in a 6 gram syringe.
