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.

- Refer to the standard wavelength range of DELOLUX 20/50/80 lamps:
