Norland NOA 87
Norland Optical Adhesive 87 is an adhesive that will cure optically clear when exposed to long wavelength ultraviolet or visible light (blue-violet). The adhesive has low viscosity and meets the Bellcore specifications of 85C/85RH for 2000 hours. NOA 86 is recommended for bonding glass or plastics. This adhesive can be 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 .
When fully cured, NOA 87 has very good adhesion and solvent resistance, but it has not reached its optimum adhesion to glass. This will come with aging over a period of about 1 week in which a chemical bond will form between the glass and adhesive. This optimum adhesion can also be obtained by aging at 50C for 12 hours.
NOA 87 can withstand temperatures before aging from -15C to 60C when used for glass bonding. After aging, it will withstand temperatures from -30C to 90C.
Keep NOA 87 in a cool (5-22 ° C) dark place. If refrigerated, allow the adhesive to come to room
temperature before using
Care should be taken in handling this material. The Material Safety Data Sheet should be read for
this product. Prolonged contact with skin should be avoided and affected areas should be washed
thoroughly with copious amounts of soap and water. If adhesive gets into eyes, flush with water for
15 minutes and seek medical attention.
