NOA 148 Optical Adhesive 1oz bottle

Product information "NOA 148 Optical Adhesive 1oz bottle"

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.

NBA 107 Blocking Adhesive 10g syringe
Refractive Index 1.51; 350 cps Viscosity at 25°C NBA 107 (10g syringe) is a single component, UV curing adhesive used for temporary bonding of lenses to metal polishing mounts or where bonded components need to be easily separated in the future. 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 107 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 readily accomplished by heating in hot water with a small amount of detergent or wetting agent added or with 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. Typical Properties of NBA 107   Solids 100% Elongation at Failure 5% Modulus (psi) 800 Tensile (psi) 76 Hardness - Shore D 15   Shelf life of the liquid is at least 6 months at room temperature if stored in the original container away from UV light. 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.
