How to apply shadowless glue to the cover of crystal photo album How to apply shadowless glue to the cover of crystal photo album can make the bonding effect more uniform and better? Please advise.
1. One of the two objects to be bonded is transparent, and its surface is clean, dry and free of grease;

2. Apply UV shadowless glue on one side, close both sides, and illuminate with ultraviolet lamp or high-pressure mercury lamp with appropriate wavelength (generally 365 nm-400 nm) and energy to ensure that the light can really penetrate the bonding part;

3. It is suggested that the residual glue on the workpiece should be removed when the initial positioning is carried out for about 6 seconds, and then re-irradiated until it is completely cured;

4. The curing time varies according to different preparation materials, adhesive layer thickness and ultraviolet intensity. It is suggested that users buy an ultraviolet intensity tester and do a light intensity test before bonding to reduce the rejection rate;

5. The air temperature also has a little influence on the activity of the adhesive, and the curing time should be appropriately extended when the air temperature is low;

6. When operating, don't forcibly squeeze and repeatedly rub the materials to be bonded. It is recommended to use a fixed tool;

7, plastic bonding, should consider the content of ultraviolet absorbent in plastic, too high content will seriously affect the ultraviolet transmittance, which also has a significant impact on the curing efficiency of glue, and even lead to the glue can not be cured;

8. Low viscosity products are recommended for large area bonding. If possible, it is best to buy vacuum equipment and stick it in a vacuum environment to remove bubbles and improve the yield;

9. The above description is for reference only, and the specific operation needs the customer to make appropriate adjustments according to the specific situation.
