Product information "NOA 85 Optical Adhesive 1oz bottle"
Viscosity at 25°C: 200 cps, Refractive Index: 1.46
Norland Optical Adhesive NOA 85 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 85 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 85 is designed to give the best possible optical bond when using plastic to plastic or plastic to glass substrates. NOA 85 has excellent adhesion to CR-39, polarized film, Delrin®, nylon, cellulose acetate butyrate, polycarbonate, acrylics and glass.
