Product information "NOA 88 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.

Refractive Index 1.46; 200 cps Viscosity at 25°C Norland Optical Adhesive NOA 85 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 85 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 85 is designed to give the best possible optical bond when using plastic to plastic or plastic to glass substrates. NOA 85 has excellent adhesion to CR-39, polarized film, Delrin®, nylon, cellulose acetate butyrate, polycarbonate, acrylics and glass.Typical Properties of NOA 85 Solids 100% Elongation at Failure 111% Modulus of Elasticity (psi) 9340 Tensile Strength (psi) 1,500 Hardness - Shore D 40 Shelf life of the liquid is at least 4 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 1.48; 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 1.524; 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.
