Application area:
- Temperature to use range: -400C ~ +1300C, depending on the application, other limits may be more reasonable.
- Specialized in bonding components in camera modules, chips bonding, sensors, materials such as glass/metal, ... fast curing;
- In order to use effectively, the adhesive should be placed in a special DELO's dispenser, the bonded surface should be clean, dry, free of dirt or grease;
- Recommend to use DELOTHEN cleaner or DELOTHEN EP for glass surface to clean and active bonded surface.
- Glue dirt can be cleaned by acetone or BDGA (butyldiglykolaxetate), do not use alcoholic or hydrous cleaners for this case.

Curing:
- Fixing by curing with UVA light in a wavelength range of 320 – 420 nm in 1 ~ 5s.
- The next, curing by heat in a temperature range of +80oC ~ +130 oC is mandatory to complete curing. The time between the fixing step and heat curing should not be longer than 1 hour.
- The adhesive feature needs a short time to achieve and final strength after 24h from the heat curing step.
- Some physical properties can be changed if increase curing speed and actual curing time are dependent on the heating time of the components, experient to give optimal curing time is necessary.
