三．TYPICAL CURING PERFORMANCE
Themis TV8000 can be cured by exposure to UV and/or visible light of sufficient intensity. To obtain full cure on surfaces exposed to air, radiation @ 220 to 260 nm is also required. The speed of cure will depend upon the UV intensity and spectral distribution of the light source, the exposure time and the light transmittance of the substrates.
Stress Cracking: Liquid adhesive is applied to a polycarbonate bar 6.4 cm by 13 mm by 3 mm which is then flexed to induce a known stress level. Stress Cracking, ASTM D 3929, minutes:
17 N/mm² stress on bar: >15
Fixture Time:
Fixture time is defined as the time to develop a shear strength of 0.1N/mm² .
UV Fixture Time, Glass microscope slides, seconds:
Black light, Zeta® 7500 light source; 6 mW/cm² , measured @ 365 nm: ≤18
Metal halide bulb (doped), Zeta®7400;30 mW/cm² , measured @ 365 nm: 5 to 10
Electrodeless, H & V bulbs; 50 mW/cm² , measured @ 365 nm: <5
Electrodeless, D bulb:50 mW/cm² , measured @ 365 nm: <5

六．Directions for use:
1、This product is light sensitive; exposure to daylight, UV light and artificial lighting should be kept to a minimum during storage and handling.
2、The product should be dispensed from applicators with black feedlines.
3、For best performance bond surfaces should be clean and free from grease.
4、Cure rate is dependent on lamp intensity, distance from light source, depth of cure needed or bondline gap and light transmittance of the substrate through which the radiation must pass.
5、Recommended intensity for cure in bondline situation is 5mW/cm² minimum (measured at the bondline) with an exposure time of 4-5 times the fixture time at the same intensity.
6、For dry curing of exposed surfaces, higher intensity UV is required (100 mW/cm² ).
