Introduce:
- DELO DUALBOND GE4949 is a modified acrylate adhesive that cures by UV and air humidity in just a few seconds;
- Glue has good tensile-equalizing thanks to its high elongation at tear;
- Compliant RoHS standards according to 2015/863/EU;
- Compliant with VOC content limit according to GB33372-202 regulation.

Application:
- Multi-field application, especially suitable for bonding materials such as glass/plastic, glass/PA, glass/glass, glass/metal;
- The response temperature of the glue after curing is in the range of -40 o C ~ +120 o C, depending on specific applications there may be other limits;
- Glue is mainly used in adhesive camera modules in smartphones.

Instruction:
- Glue is produced for direct use without mixing, the use effect will be better if combined with the DELOMAT 100 specialized glue set;
- The surface to be bonded must be cleaned, dried, and free of any impurities such as dust, machine oil, etc.
- It is recommended to use DELO cleaning products such as DELOTHEN for plastic and metal surfaces, DELOTHEN EP for glass surfaces for optimal results.
Curing:
- The glue can be cured by UV light in the wavelength range 320 ~ 450 nm, and by air humidity (65 ~ 80%) for occluded areas.
- Moisture curing will start on the surface of the adhesive, forming a thin film after a few hours, the curing speed according to the thickness of the glue is approximately 2mm/24h.
