*Curing Instructions: Curing speed varies with the intensity of the UV lamp, light distance, light source spectral distribution, exposure time and substrate transmittance.
Notes
1. Clean the bonding surface, make it dry and free of grease;
2. Do not forcefully squeeze or repeatedly rub the substrate to be bonded during operation. Continue to illuminate for 30 to 60 seconds after positioning to achieve higher intensity.
3. The UV curing rate depends on the intensity of the bulb, the distance between the light source and the adhesive layer, the required curing depth or gap between the adhesive layers, and the light transmittance of the substrate;
Storage
8～26℃, store in a sealed, cool, dark and dry place, away from ultraviolet rays or sunlight.
