The F-UVE-81 (NOA 81) UV-curing liquid polymer adhesive is suited for fast, high-precision bonding of optics. The transmission of a 0.25 mm thick adhesive layer is greater than 98% from 400–2000 nm.
The F-UVE-81 adhesive is fast curing for tacking or bonding applications, and can be pre-cured in just seconds and fully-cured in minutes with a 350–380 nm, 100 mW UV mercury spot lamp. Available in 1 oz. (30 ml) applicator bottles.
