NOA 81 Optical Adhesive 1oz bottle

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 1.48; 1500-2000 cps Viscosity at 25°C Norland Optical Adhesive 148 is clear liquid adhesive that will cure when exposed long wavelength ultraviolet light. NOA 148 is recommended for bonding glass to glass. Adhesion is also good to cellulose acetate butyrate. NOA 148 is cured by ultraviolet light between 315 and 395 nm. Full cure requires 6 Joules/cm2. The adhesive exhibits oxygen inhibition and must be cured under an inert atmosphere if used as a coating to assure surface is tack free.Typical Properties of NOA 148 Color  Clear Keep NOA 148 in a cool (5-22°C) dark place. If refrigerated, allow the adhesive to come to room temperature before using.

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 (5°C-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; Viscosity at 25°C 300 cps 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.
