Viscosity at 25°C: 15-25 cps, Refractive Index: 1.3685
Norland Optical Adhesive 13685 is clear liquid adhesive that will cure when exposed long wavelength ultraviolet light. NOA 13685 is recommended for bonding for glass to glass. Adhesion is also good to cellulose acetate butyrate. NOA 13685 is cured by ultraviolet light between 315 and 395 nm. Full cure requires 6 Joules/cm2. The adhesive exhibits oxygen inhibition and must be cured under an inert atmosphere if used as a coating to assure surface is tack free.
