NOA 76 Optical Adhesive 10g syringe

Refractive Index 1.54; 5,000 cps Viscosity at 25°C Norland Optical Adhesive 68 ("NOA68")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 of optical materials where the bonding surface can be exposed to light. The use of NOA 68 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.NOA 68 is designed to give improved adhesion to many plastics such as acrylic, polycarbonate and cellulose acetate butyrate. In addition to plastics, NOA 68 has good adhesion to glass and metals and can be used to bond combinations of the three. Suggested uses for NOA 68 include bonding compound plastic lenses, laminating polarized film between glass or plastic, mounting plastic lenses in metal or plastic mounts and bonding cover glasses.Typical Properties of NOA 65 Solids 100% Elongation at Failure 80% Modulus of Elasticity (psi) 20,000 Tensile Strength (psi) 2,500 Hardness - Shore D 60 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 1.6; 155 cps Viscosity at 25°C Norland Optical Adhesive 72 ("NOA72 10g syringe")is an optically clear, liquid adhesive that will cure when exposed to either long wavelength ultraviolet light or visible light. This one part,low viscosity adhesive is 100% solids and offers advantages in optical bonding applications. The use of NOA 72 eliminates premixing, drying or heat curing operations common to other adhesive systems.NOA 72 is recommended for bonding plastics such as acrylic, polycarbonate, cellulose acetate butyrate or glass where low UV light transmission prevents curing of other adhesives. Typical applications would be bonding of compound lenses, laminating polarized film between glass or plastic or bonding leaded glass.NOA 72 is cured by ultraviolet light between 315 to 400 nanometers and visible light between 400 to 450 nanometers. The peak absorption wavelengths are 320, 365 and 420 nm. Full cure requires 5 Joules/sq. cm of energy between 315 and 450 nm.Typical Properties of NOA 72 Hardness - Shore D 75 Dielectric Constant at 1 MHz 3.98 Dielectric Strength (V/mil) 456 Dissipation Factor at 1 MHz .0351 Volume Resistivity (ohm/cm) 7.37 x 10 to the 14 power Surface Resistivity (ohm) 3.73 x 10 to the 12 power Shelf life of the liquid is a minimum of 4 months from the date of shipment, refer to the package label for the actual expiration date, 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 1.50; 8000-11000 cps Viscosity at 25°C Norland Optical Adhesive 78 (10g syringe) is a clear, colorless, liquid photopolymer that will cure when exposed to ultraviolet light 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 78 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 78 is designed to give the best possible optical bond when using plastic to plastic or plastic to glass substrates. NOA 78 has excellent adhesion to CR-39, polarized film, Delrin®, nylon, cellulose acetate butyrate, polycarbonate and acrylics.Typical Properties of NOA 78 Color Slight yellow tint Modulus (psi) 1140 Tensile (psi) 649 Elongation at failure 57% Hardness - Shore D 55 Dielectric Constant at 1 MHz 4.87 Dissipation Factor at 1 MHz .0.092 Volume Resistivity (ohm/cm) 22 x 10 to the 15 power Surface Resistivity (Megohms) 2.05 x 10 to the 12 power Dielectric Strength (volts) 624  NOA 78 can withstand temperatures from -20C to 60C.Shelf life of the liquid is at least 4 months from the date of shipment if stored in a cool (5-20C), dark place in the original container. If refrigerated, allow the adhesive to come to room temperature prior to use.
