Product information "NOA 83H Optical Adhesive 10g syringe"
Viscosity at 25°C: 250 cps, Refractive Index: 1.56
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.
