NOA 71 Optical Adhesive 10g syringe

Refractive Index 1.56; 300 cps Viscosity at 25°C Norland Optical Adhesive 61 is a clear, colorless, liquid photopolymer that will cure when exposed to ultraviolet light. Since it is a one part system and 100% solids, it offers many advantages in bonding where the adhesive can be exposed to U.V. light. The use of NOA 61 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 61 meets Federal Specification MIL-A-3920 for optical adhesives and is approved for use on all government contracts specifying such adhesives. The adhesive is designed to give the best possible optical bond to glass surfaces, metals, fiberglass and glass filled plastics. NOA 61 is recommended for bonding lenses, prisms and mirrors for military, aerospace and commercial optics as well as for terminating and splicing optical fibers.Typical Properties of NOA 61 Solids 100% Elongation at Failure 38% Modulus of Elasticity (psi) 150,000 Tensile Strength (psi) 3,000 Hardness - Shore D 85 Shelf life of the liquid is at least 4 months from the date of shipment if stored in a cool (50C - 220C), dark place in the original container.

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 1.51; 3500-5500 cps Viscosity at 25°C Norland Optical Adhesive 76 (NOA 76 10g syringe), also known as NOA 76A, is an optically clear, liquid adhesive that will cure when exposed to long wavelength ultraviolet light. It is also sensitive to visible light between 400 - 450 nanometers which will assist in producing faster cures when curing through UV absorbing materials. This one part, moderate viscosity adhesive is 100% solids and offers advantages in optical bonding applications. The use of NOA 76 eliminates premixing, drying or heat curing operations common to other adhesive systems.NOA 76 is recommended for bonding glass to plastic.

Refractive Index 1.55; 250-350 cps Viscosity at 25°C 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.
