NOA 72 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 1.55; 200-300 cps Viscosity at 25°C Norland Optical Adhesive 86 is an adhesive that will cure optically clear when exposed to long wavelength ultraviolet or visible light (blue-violet). The adhesive has low viscosity and meets the Bellcore specifications of 85C/85RH for 2000 hours. NOA 86 is recommended for bonding glass or plastic. NOA 86 is cured by ultraviolet light between 315 to 400 nanometers and visible light between 400 to 420 nanometers. The peak absorption wavelengths are 325, 365 and 400 nanometers. Minor absorption wavelengths are 410 and 420 nm. Full cure requires 2.5 Joules/cm 2 . When fully cured, NOA 86 has very good adhesion and solvent resistance, but it has not reached its optimum adhesion to glass. This will come with aging over a period of about 1 week in which a chemical bond will form between the glass and adhesive. This optimum adhesion can also be obtained by aging at 50C for 12 hours.NOA 86 can withstand temperatures before aging from -15C to 90C when used for glass bonding. After aging, it will withstand temperatures from -125C to 125C.Typical Properties of NOA 86 Liquid Color Slight yellow tint that disappears upon curing Modulus (psi) 7,834 Tensile (psi) 360,400 Elongation at Failure 2.8% Hardness - Shore D 75 Keep NOA 86 in a cool (5-22 °C) dark place.

Refractive Index 1.51; 3500-5500 cps Viscosity at 25°C Norland Optical Adhesive 76 (NOA 76 10g syringe), also known as NOA 76A, is an optically clear, liquid adhesive that will cure when exposed to long wavelength ultraviolet light. It is also sensitive to visible light between 400 - 450 nanometers which will assist in producing faster cures when curing through UV absorbing materials. This one part, moderate viscosity adhesive is 100% solids and offers advantages in optical bonding applications. The use of NOA 76 eliminates premixing, drying or heat curing operations common to other adhesive systems.NOA 76 is recommended for bonding glass to plastic. The adhesive has best adhesion with plastics such as acrylic, polycarbonate and cellulose acetate butyrate with typical applications being glass to plastic bonding or laminating polarized film between glass.Typical Properties of NOA 76 (76A) Color Clear Modulus (psi) 970 Tensile (psi) 450 Elongation at failure 47% Hardness - Shore D 60 Dielectric Constant at 1 MHz 3.33 Dissipation Factor at 1 MHz .0346 Volume Resistivity (ohm/cm 4.723 x 10 to the 12 power Surface Resistivity (Megohms) 2.148 x 10 to the 12 power Dielectric Strength (volts) 131 The shelf life of NOA 76 liquid material is at least 4 months from the date of shipment 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; 250 cps Viscosity at 25°C Norland Optical Adhesive 83H ("NOA83H") 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 bondoptical components. In addition to UV light, heat can also be usedto cure this one part adhesive.The outstanding characteristic of this material 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 83H will not gel up in dispenser tips or cure before you want it to.Typical Properties of NOA 83H Solids 100% Elongation at Failure 30% Modulus of Elasticity (psi) 160,000 Tensile Strength (psi) 3,500 Hardness - Shore D 85 Shelf life of the liquid is at least 4 months from the date of shipment if stored in a cool (5-22° C), dark place in the original container. If refrigerated, allow the adhesive to come to room temperature prior to use.
