NOA 83H Optical Adhesive 1oz bottle

Refractive Index 1.3825; 5600 cps Viscosity at 25°C Norland Optical Adhesive 13825 is clear liquid adhesive that will cure when exposed long wavelength ultraviolet light. NOA 13825 is recommended for bonding for glass to glass. Adhesion is also good to cellulose acetate butyrate. NOA 13825 is cured by ultraviolet or visible light between 315 to 450 nm. Full cure requires 6 Joules/cm 2 . The adhesive exhibits oxygen inhibition when used as a coating. To overcome this the adhesive must be cured under an inert atmosphere, such as nitrogen. Keep NOA 13825 in a cool(5-22°C) dark place. If refrigerated, allow the adhesive to come to room temperature before using.

Refractive Index 1.55 Viscosity at 25°C 250-350 cps Norland Optical Adhesive 86H is an adhesive that will cure optically clear when exposed to long wavelength ultraviolet or visible light (blue-violet) or heat. The adhesive has low viscosity and meets the Bellcore specifications of 85C/85RH for 2000 hours as well as being USP Class VI biocompatible NOA 86H is recommended for bonding glass or plastic. NOA 86H 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 .In addition to the UV cure, NOA 86H contains a latent heat catalyst that can quickly cure areas that do not see the ultraviolet light. The catalyst allows the adhesive to cure in 10 minutes at 125°C in a convection oven, or 3 hours at 80° C. Faster cure times are possible with infrared ovens. Areas in contact with air will cure tacky unless exposed to UV light or given the 125° C cure. Temperatures less than 80°C will not activate the adhesive. The advantage of the heat cure is to bring partially cured adhesive to full cure to get the maximum physical properties of the adhesive. The heat cure is not required if all the adhesive receives proper exposure to UV or visible light. Typical Properties of NOA 86H Temperature Range -125°C to 125°C Elongation at Failure 2.8 % Modulus of Elasticity (psi) 360,400 Tensile Strength (psi) 7,834 Hardness - Shore D 75 75 Shelf life of the liquid is a minimum of 6 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.
