Product information "NOA 84 Optical Adhesive 1oz bottle"
Viscosity at 25°C: 40-75 cps, Refractive Index: 1.46
Norland Optical Adhesive NOA 84 is a clear, colorless, liquid photopolymer that will cure when exposed to ultraviolet light and 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 84 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 84 is designed to give the best possible optical bond when using plastic to plastic or plastic to glass substrates. NOA 84 has excellent adhesion to CR-39, polarized film, Delrin®, nylon, cellulose acetatebutyrate, polycarbonate, acrylics and glass.
