Viscosity at 25°C: 155 cps, Refractive Index: 1.6

Norland Optical Adhesive 72 ("NOA72 10g syringe")is an optically clear, liquid adhesive that will cure when exposed to either long wavelength ultraviolet light or visible light. This one part,low viscosity adhesive is 100% solids and offers advantages in optical bonding applications. The use of NOA 72 eliminates premixing, drying or heat curing operations common to other adhesive systems.

NOA 72 is recommended for bonding plastics such as acrylic, polycarbonate, cellulose acetate butyrate or glass where low UV light transmission prevents curing of other adhesives. Typical applications would be bonding of compound lenses, laminating polarized film between glass or plastic or bonding leaded glass.

NOA 72 is cured by ultraviolet light between 315 to 400 nanometers and visible light between 400 to 450 nanometers. The peak absorption wavelengths are 320, 365 and 420 nm. Full cure requires 5 Joules/sq. cm of energy between 315 and 450 nm.
