Viscosity at 25°C: 20-30 cps, Refractive Index: 1.42
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 and 395 nm. Peak absorption is 365nm. Full cure requires 6 Joules/cm2 of UV energy. The adhesive exhibits oxygen inhibition and must be cured under an inert atmosphere if used as a coating to assure surface is tack free.
