NOA-65

The cured adhesive is very flexible and was designed to minimize strain. NOA 65 is especially suitable where the adhesive cross section would be relatively thick. NOA 65 has enough elasticity to keep strain to a minimum even when dissimilar materials with different coefficients of expansion are bonded together. Typical applications would be potting of lenses in metal mounts, bonding plastic to glass and cold blocking.

NOA 65 is cured by ultraviolet light with a maximum absorption within the range of 350-380 nanometers. The polymer has minimum oxygen inhibition, and therefore any surfaces in contact with air will be non-tacky when fully cured.

Pre-Curing

room temperature 22°C using a long wave black light UV-light source (350-380 nm, 100 Watt) ca. 15 cm above the element
UV-Light (350-380 nm, 15 Watt) ca. 8 cm above the element.

ca. 15 seconds (1-10 mil, 100 Watt)
ca. 60 seconds (1-10 mil, 15 Watt)
