Information

UV adhesives are also known as shadowless adhesives, photosensitive adhesives and ultraviolet light curing adhesives. A shadowless adhesive is an adhesive that must be cured by ultraviolet light. It can be used as an adhesive, but also as a paint, coating, ink, etc. The glue used. Light-curing adhesives are composed of the main components such as base resin, active monomer, photoinitiator, and auxiliary agents such as stabilisers, crosslinkers and coupling agents.

Features of UV-curable adhesives: single component, solvent-free, non-polluting, non-mixed, UV-curable at room temperature. Excellent optical properties, high light transmission of the cured adhesive layer. Good resistance to weathering, yellowing and humidity. Adhesive layer is flexible, impact and vibration resistant. Wide range of bonding materials, high bond strength, materials such as plastics, glass and most metals can be bonded to each other. The fast curing speed and simple equipment, requiring only a lamp or conveyor belt, make it suitable for automated work and increase production efficiency.

1、Fast surface drying, low curing temperature  

2、Good levelling, simple process

3、Excellent sealing and water barrier

4、Flexible adhesive layer, can adapt to a variety of temperature environments

5、No solvent, low stimulation, no pollution to the air

Substrate treatment: Clean the surface of the substrate to ensure that it is free from impurities, oil and dirt. Pre-treatment: Take the product out of the -40℃ refrigerator and re-temperature it to 25℃ before use, keep it vertical during the re-temperature process and re-temperature it for about 45min. Dispensing: avoid UV light during the rewarming process, the best working temperature is 25°C. To ensure the adhesive effect, it is recommended to use a dispensing machine (the specific process parameters of the dispensing machine can be adjusted according to the actual use of the customer).

Curing: recommended to use the wavelength of 405nm light curing equipment for curing, the thickness of the adhesive layer should be controlled within 250 ± 10um, single-sided curing irradiation time > 25 seconds (curing time depends on the energy of the lamp), the product needs to be cured on both sides, such as equipment allows, double-sided curing can be carried out at the same time. After curing; will sample UV curing, room temperature for 48 hours, can be fully cured.
