NOA 81 Optical Adhesive 10g syringe

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. If refrigerated, allow the adhesive to come to room temperature prior to use.

 Refractive Index 1.56; 200 cps Viscosity at 25°C Norland Optical Adhesive 71 ("NOA71") is an optically clear, liquid adhesive that will cure when exposed to long wavelength ultraviolet light (10g syringe). The adhesive is a one-part, 100% solids material that offers advantages in bonding applications that require optical clarity or require fast cure times and long term stability over a wide range of temperatures. The use of NOA 71 eliminates premixing, drying, or heat curing operations common to other adhesive systems.NOA 71 was formulated to provide a strong bond to glass surfaces. This adhesive can also be used for adhering to other substrates, such as metal, fiber- glass, and glass filled plastics. Typical applications are laminating solar cells, holographic plates, flat panel displays and touch screens or as a clear coating on plastic or metal.NOA 71 is cured with long wavelength UV light from 315 to 400 nanometers with peak absorption at 365 nm. The amount of energy required for full cure is 3.5 Joules/sq. cm of UV light.

If refrigerated, allow the adhesive to come to room temperature prior to use.

Refractive Index: 1.56; 300 cps Viscosity at 25°CNOA 61 strong, heat resistant optical adhesive with refractive index 1.56 and curing between 320 - 380 nm UV light MIL-A-3920 compliant (10g syringe)

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. If refrigerated, allow the adhesive to come to room temperature prior to use.
