Application:
- Applied in many fields, especially the production of electronic components, microchips, electrical engineering, telephones... used to quickly fix components after irradiation, bringing high durability.
- In order to use the adhesive effectively, it is recommended to place the glue in the DELO special dispersant, the surface to be bonded should be clean, dry, free of dust or grease.
- For a clean and well-activated surface, use the DELOTHEN surface cleaner.
- Use DELOTHEN EP for more cleaning on glass surfaces.
- Use the DELOMAT 100 gluing system and G30 or higher dispensing needle.
Curing:
- Using a UV lamp with a wavelength of 365nm. In the shadowed area, the glue can be heat dried in the range of 80~130 0 C. Both of the above methods can be used independently.
- Refer to the standard wavelength range of DELOLUX 20/50/80 lamps:
