Product information "NOA 85V optical adhesive 1oz bottle"
Viscosity at 25°C: 200 cps, Refractive Index: 1.46
Norland Optical Adhesive NOA 85V 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 85V 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 85V is designed to give the best possible optical bond when using plastic to plastic or plastic to glass substrates. NOA 85V has excellent adhesion to CR-39, polarized film, Delrin®, nylon, cellulose acetate butyrate, polycarbonate, acrylics and glass. NOA 85V also has excellent clarity, low shrinkage and a slight 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 85V is cured by ultraviolet light with maximum absorption within the range of 320-400 nanometers and visible light between 400 and 450 nanometers. The peak absorption wavelengths are 325, 365 and 405 nanometers. The recommended energy required for full cure is 3.5 Joules/cm squared.
