Norland Optical Adhesive NOA 89H is a clear, colorless, liquid photopolymer that will cure when exposed to ultraviolet  light. Since it is a one part system and 100% solids, it offers many advantages in bonding where the adhesive can be exposed to UV light. The use of NOA 89H eliminates premixing, drying or heat curing operations common to other adhesive systems. Curing time is remarkably fast, and is dependent upon the thickness applied and the amount of ultraviolet light energy available.

NOA 89H is designed to give the best possible optical bond when bonding glass to glass substrates or as a coating.  NOA 89H also has excellent clarity, low shrinkage and a flexibility that make it superior to other materials for optical bonding. These characteristics are important in order for the user to produce high quality optics and achieve long term performance under changing environments. NOA 89H is cured by ultraviolet light with maximum absorption within the range of 310-395 nanometers. 

The peak absorption wavelengths is 365 nanometers. The recommended energy required for full cure is 3.5 Joules/cm 2 for long wave UV.

Shelf life of the liquid is a minimum of 4 months from the date of shipment, refer to the package label for the actual expiration date, if stored in a cool (5-22° C), dark place in the original container.  If refrigerated, allow the adhesive to come to room temperature prior to use.
