NOA 87 Optical Adhesive 1oz bottle

Refractive Index 1.55 Viscosity at 25°C 250-350 cps Norland Optical Adhesive 86H is an adhesive that will cure optically clear when exposed to long wavelength ultraviolet or visible light (blue-violet) or heat. The adhesive has low viscosity and meets the Bellcore specifications of 85C/85RH for 2000 hours as well as being USP Class VI biocompatible NOA 86H is recommended for bonding glass or plastic. NOA 86H is cured by ultraviolet light between 315 to 400 nanometers and visible light between 400 to 420 nanometers. The peak absorption wavelengths are 325, 365 and 400 nanometers. Minor absorption wavelengths are 410 and 420 nm. Full cure requires 2.5 Joules/cm 2 .In addition to the UV cure, NOA 86H contains a latent heat catalyst that can quickly cure areas that do not see the ultraviolet light. The catalyst allows the adhesive to cure in 10 minutes at 125°C in a convection oven, or 3 hours at 80° C. Faster cure times are possible with infrared ovens. Areas in contact with air will cure tacky unless exposed to UV light or given the 125° C cure. Temperatures less than 80°C will not activate the adhesive. The advantage of the heat cure is to bring partially cured adhesive to full cure to get the maximum physical properties of the adhesive. The heat cure is not required if all the adhesive receives proper exposure to UV or visible light.

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.

Refractive Index 1.56; 250 cps Viscosity at 25°C Norland Optical Adhesive 88 ("NOA 88") is an optically clear, liquid adhesive that will cure when exposed to long wavelength ultraviolet light. The adhesive is a one-part, 100% solids material that offers advantages in optical bonding applications. The use of NOA 88 eliminates premixing, drying, or heat curing operations common to other adhesive systems. Curing time can be regulated by the end user by varying the intensity of the curing source.NOA 88 was formulated as a low outgassing (CVCM) and low Total Mass Loss (TML) adhesive. The ideal applications for this adhesive is for coating of parts destined for space exploration, bonding of high tech computer components,adhering parts in very sensitive instruments and coating sensitive components.NOA 88 is cured by ultraviolet light (315 nm to 395nm) with maximum sensitivity at 365 nanometers. The adhesive requires 5 Joules/sq.cm of energy to fully cure a 25 to 50 micron bond. The material has low oxygen inhibition, so adhesive exposed to air will cure tack-free with sufficient exposure to UV light.Typical Properties of NOA 88 Solids 100% Refractive Index of Monomer 1.52 Elongation at Failure 41% Modulus of Elasticity (psi) 131,000 Tensile Strength (psi) 2,000 Hardness - Shore D 90 Total Mass Loss (TML) 1.07% Collected Volatile Condensable Material (CVCM) <0.01% Dielectric Constant (1 MHz) 4.06 Dielectric Strength (V/mil) 457 Dissipation Factor (1 MHz) 0.0341 Volume Resistivity (ohm-cm) 6.85 x 10 to the 14 power Surface Resistivity (MEgohms) 3.71 x 10 to the 12 power The shelf life of the liquid material is at least four months from the shipment date if kept in a cool (5-22° C) dark place in the original container.

Refractive Index 1.56; 300 cps Viscosity at 25°C Norland Optical Adhesive 81 ("NOA81") is a single component liquid adhesive that cures in seconds to a tough, hard polymer when exposed to ultraviolet light. It is recommended as an extremely fast and efficient way to precisely bond optical components or fiber optics. It can be cured in a thin layer between two transparent substrates or applied as a dropto form a bridge between two components. Exposure to UV light quickly cures the adhesive and holds the components in place.The outstanding characteristic of this adhesive is its extremely fast cure. Thin films can be initially set in under 10 seconds and thick films in 20 seconds using the light sources listed below. It is also extremely stable when not exposed to UV light. NOA 81 will not gel up in dispenser tips or cure before you want it to.Typical Properties of NOA 81 Solids 100% Elongation at Failure 25% Modulus of Elasticity (psi) 200,000 Tensile Strength (psi) 4,000 Hardness - Shore D 90 Shelf life of the liquid is at least 6 months from the date of shipment if stored in a cool (5-22° C), dark place in the original container.

When fully cured, NOA 86 has very good adhesion and solvent resistance, but it has not reached its optimum adhesion to glass. This will come with aging over a period of about 1 week in which a chemical bond will form between the glass and adhesive. This optimum adhesion can also be obtained by aging at 50C for 12 hours.NOA 86 can withstand temperatures before aging from -15C to 90C when used for glass bonding. After aging, it will withstand temperatures from -125C to 125C.Typical Properties of NOA 86 Liquid Color Slight yellow tint that disappears upon curing Modulus (psi) 7,834 Tensile (psi) 360,400 Elongation at Failure 2.8% Hardness - Shore D 75 Keep NOA 86 in a cool (5-22 °C) dark place.
