Product information "NOA 78 Optical Adhesive 10g syringe"
Refractive Index 1.50; 8000-11000 cps Viscosity at 25°C
Norland Optical Adhesive 78 (10g syringe) is a clear, colorless, liquid photopolymer that will cure when exposed to ultraviolet light or visible light (blue-violet). 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 78 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 78 is designed to give the best possible optical bond when using plastic to plastic or plastic to glass substrates. NOA 78 has excellent adhesion to CR-39, polarized film, Delrin®, nylon, cellulose acetate butyrate, polycarbonate and acrylics.
