Introduce:
- This is a type of acrylate glue that can be cured by UV and light, high viscosity, suitable for bonding a variety of materials such as glass, PC plastic, PMMA, PA6, PBT, etc;
- Components: modified acrylate, 1-component adhesive, solvent-free, and thixotropic;
- Compliant RoHS standard 2015/863/EU;
- Passed UL 94 HB test standards by independent metrology institutes.
PHOTOBOND AD494 glue with different bottle volumes
Application:
- Applied in many fields with a variety of materials such as plastic-plastic, plastic-glass, glass-glass, metal-plastic, especially suitable when attaching glass parts to plastic frames or mounting bases glasses;
- The ability to cure both UV and visible light at the same time allows curing many components that are difficult for UV light to penetrate;
- Good elastic balance strength thanks to the high elongation at the tear characters;
- The high viscosity allows the adhesive to be as thick as 2 mm;
- Cured adhesive can be used in temperature range: -40 0 C ~ 150 0 C, depending on the application.

Component materials:
- Socket: PBT Pocan 4225
- Lamp body: Glass
Applying process:
 |  |  |
| Plasma processing | Apply glue with DELO-DOT | Curing glue with DELOLUX 80 lamp |
Curring:
- Minimum UV curing time:
+ 14s with UV lamp – light intensity 60 mW/cm 2
+ 9s with LED – light intensity 200 mW/cm 2
- Use UV or visible light with a wavelength from 320~450nm. DELOLUX lamps are designed to be compatible with the AD494. Increasing the light intensity will shorten the irradiation time and conversely, decreasing the light intensity will prolong the glue drying process.
- Refer to the standard wavelength range of the DELOLUX 20/50/80. lamp
