Product information "NOA 89 Optical Adhesive 1oz bottle"
Viscosity at 25°C: 15-20 cps, Refractive Index: 1.51
Norland Optical Adhesive NOA 89 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 89 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 89 is designed to give the best possible optical bond between glass to glass substrates and as a coating. NOA 89 also has excellent clarity, and a slight flexibility that makes it superior 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.
