NOA 87 Optical Adhesive 1oz bottle

Refractive Index 1.524; 1200 cps Viscosity at 25°C Norland Optical Adhesive 65 ("NOA65") is a clear, colorless, liquid ph2otopolymer that will cure when exposed to ultraviolet light. Since it is a one part system and 100% solids, it offers many advantages in bonding of optical materials where the bonding surface can be exposed to light. The use of NOA 65 eliminates premixing, drying and heat curing operations common to other optical adhesive systems. Curing time is remarkably fast, and is dependent upon the thickness applied and the amount of ultraviolet light energy available. The cured adhesive is very flexible and was designed to minimize strain. NOA 65 is especially suitable where the adhesive cross section would be relatively thick. NOA 65 has enough elasticity to keep strain to a minimum even when dissimilar materials with different coefficients of expansion are bonded together. Typical applications would be potting of lenses in metal mounts, bonding plastic to glass and cold blocking. Typical Properties of NOA 65 Solids 100% Elongation at Failure 80% Modulus of Elasticity (psi) 20,000 Tensile Strength (psi) 1,500 Hardness - Shore D 50 Temperature Range -15 to 60° C   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.

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.
