Regarding the issue of how to use UV adhesive, it is necessary to understand the customer's adhesive application purpose (bonding, coating, temporary protection, etc.), application requirements, and operating environment in order to provide a specific and detailed usage step. Here, some common usage steps and precautions are summarized for reference.

1. At least one of the two objects to be bonded should be transparent and have a clean, dry, and grease free surface;

2. Apply UV glue to one of the surfaces, close the two planes, and ensure that the light can penetrate the bonding area from the center to the periphery during illumination;

3. It is recommended to light for about 6 seconds (specific time depends on actual operation). During preliminary positioning, remove the remaining glue on the workpiece and then re light until it is completely cured;

4. The curing time should vary according to different preparation materials, adhesive thickness, and UV intensity. It is recommended that users purchase a UV intensity tester and conduct a light intensity test before bonding to reduce the scrap rate;

5. Temperature also has a slight impact on the activity of UV adhesive, and the curing time should be appropriately extended when the temperature is low;

6. During UV glue operation, materials that need to be bonded should not be forcefully squeezed or repeatedly rubbed, and it is recommended to use fixing tools;

7. When bonding plastic, the content of ultraviolet absorbers in the plastic should be considered. A higher content will seriously affect the transmittance of ultraviolet rays, which will also have a significant impact on the curing efficiency of the adhesive, and even lead to the inability of the adhesive to cure;

8. It is recommended to use low viscosity products for large-scale bonding. When conditions permit, it is best to purchase vacuum equipment and adhere it in a vacuum environment to remove bubbles and improve product yield.
