NBA 107 Blocking Adhesive 10g syringe

Refractive Index 1.51; 550 cps Viscosity at 25°C  NBA 108 (10g syringe) is a single component, UV curing adhesive used for temporary bonding of lenses to metal polishing mounts. This blocking adhesive is formulated to be used with polishing processes that use large amounts of liquid or use heavy grinding. The adhesive cures in minutes at room temperature by exposure to long wave UV light and eliminates the heat induced strain typical of the old fashioned hot pitch blocking methods. NBA 108 is specifically formulated to provide low shrinkage and low strain to further minimize any potential strain on the lens during the blocking process. Debonding is accomplished by soaking in acetone.The adhesive cures only by exposure to UV light in the range of 350 to 380 nanometers. Recommended light sources include mercury lamps, sun lamps, fluorescent black lights and xenon lamps. Norland Products sells a variety of light sources optimized for curing our adhesive. The adhesive needs 5 joules per centimeter squared of long wave UV energy to fully cure. Cure time will depend on the amount of UV energy the light source used generates at the surface of the adhesive.

Prolonged skin contact should be avoided and affected areas should be washed with soap and water. Avoid prolonged vapor inhalation and use in a well ventilated area.

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 (50C - 220C), dark place in the original container. If refrigerated, allow the adhesive to come to room temperature prior to use.

Refractive Index 1.54; 5000 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 1.689-1.9; Viscosity 15, 138 mPas; Transmittance 94%-97%; UV Curing Conditions 100 mW/cm², 1, 5 min; Tg +100, +125 °C Nano imprint lithography is the next generation process technology. This simple and low-cost fabrication technology enables nano-scale patterns. NTT-AT’s high refractive index, UV-curable nano imprint lithography resins provide highly functional fine patterns with high accuracy. This series’ high refractive index (RI) helps to miniaturize optical components. Resin type #18210 features a refractive index of more than 1.7 and contains solvent, good for creating a thin film (<1 µm). Solvent-free resin type #18247 enables to produce thicker layers (>2 to 3 µm) and can create nano-size patterns without a pre-baking process to evaporate the solvent. This product maintains a high refractive index of 1.689 to 1.765, depending on the light’s wavelength, keeping a high transparency in the visible wavelength range by using non-organic fillers. With the recent increase in the refractive index of glass for AR/VR, aimed at expanding the field of view, the demand for resins to match this higher RI is also increasing. Just recently, NTT-AT has developed new 1.8 and 1.9 refractive index resins with high transparency and good nanoimprintability, able to fabricate a uniform thin film by spin coating. These resins are expected to contribute to the improvement of the flexibility in optical design. NTT-AT uses high-precision refractive index control technology in the manufacture of optical adhesives to increase the concentration of high-refractive-index inorganic nanofillers and achieve high refractive index while optimizing the resin formulation. These resins are compatible with high-refractive index glasses and can create nano-patterns with a line width of 50 nm to 10 µm by nanoimprinting. They feature high light transmission in the wavelength range from 400 nm to 800 nm.

Refractive Index 1.315; 15 cps Viscosity at 25°C Norland Optical Adhesive 1315 (2g syringe) is clear liquid adhesive that will cure when exposed long wavelength ultraviolet light. NOA 1315 is recommended for bonding for glass to glass. Adhesion is also good to cellulose acetate butyrate. NOA 1315 is cured by ultraviolet light between 320 to 450 nm. Full cure requires 6 Joules/cm 2. The adhesive exhibits oxygen inhibition when used exposed to air. To overcome this the adhesive must be cured under an inert atmosphere, such as nitrogen. When used as a coating the liquid adhesive's temperature must be kept below 9C to prevent vaporization.Typical Properties of NOA 1315 Temperature Range -15°C to 90°C   Keep NOA 1315 in a cool ( 5 to 20°C) dark place. If refrigerated, allow the adhesive to come to room temperature before using.
