The NOA-85S UV-curing adhesive 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-86S is recommended for bonding glass or plastic. It is cured by ultraviolet light between 315 to 400 nanometers and visible light between 400 to 420 nm. The peak absorption wavelengths are 325, 365 and 400 nm. Minor absorption wavelengths are 410 and 420 nm. Full cure requires 2.5 Joules/cm 2.
When fully cured, NOA-86S 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 86 can withstand temperatures before aging from -15C to 90C when used for glass bonding. After aging, it will withstand temperatures from -125C to 125C.

NOA-85S uv固化胶粘剂是一种能在长波长紫外线或可见光(蓝紫色)下固化的透明胶粘剂。该胶粘剂粘度低,达到85C/85RH的Bellcore标准,使用时间为2000小时。建议使用NOA-86S粘合玻璃或塑料。紫外光在315到400纳米之间固化,可见光在400到420纳米之间固化。峰吸收波长为325、365和400nm。小吸收波长为410和420 nm。完全固化需要2.5焦耳/厘米2。
在完全固化后,NOA-86S具有很好的附着力和耐溶剂性,但未达到对玻璃的最佳附着力。这将随着大约1周的老化而产生,在玻璃和粘合剂之间会形成化学键。这种最佳的附着力也可以通过在50C下老化12小时而获得。
当用于玻璃粘结时,noa86在从-15C到90C老化前能够承受温度。经过老化后,它可以承受-125C到125C的温度。
