Norland Optical Adhesive 71 ("NOA71") is an optically clear, liquid adhesive that will cure when exposed to long wavelength ultraviolet light (10g syringe). The adhesive is a one-part, 100% solids material that offers advantages in bonding applications that require optical clarity or require fast cure times and long term stability over a wide range of temperatures. The use of NOA 71 eliminates premixing, drying, or heat curing operations common to other adhesive systems.
NOA 71 was formulated to provide a strong bond to glass surfaces. This adhesive can also be used for adhering to other substrates, such as metal, fiber- glass, and glass filled plastics. Typical applications are laminating solar cells, holographic plates, flat panel displays and touch screens or as a clear coating on plastic or metal.
NOA 71 is cured with long wavelength UV light from 315 to 400 nanometers with peak absorption at 365 nm. The amount of energy required for full cure is 3.5 Joules/sq. cm of UV light.
