UV glue | shadowless glue Guide

1. Clean and dry the bonded surface without grease;

2. Apply UV glue to one of the surfaces, close the two surfaces, and irradiate with ultraviolet lamp with appropriate wavelength (usually 365 nm) and energy or high-pressure mercury lamp. When irradiating, the light should be from the center to the periphery, and make sure that the light can penetrate to the bonding part;

3. It is suggested that the remaining glue on the workpiece should be removed after about 6S illumination and initial positioning, and then it should be re illuminated until it is completely cured.

4. Curing time should be different according to different preparation materials, adhesive thickness and UV intensity. It is suggested that users purchase ultraviolet intensity tester and test the light intensity before bonding to reduce the scrap rate;

5. The curing time should be extended when the temperature is low;

6. During the operation, it is not necessary to squeeze and repeatedly rub the materials to be bonded, and it is recommended to use fixing tools;

7. The content of UV Absorbents in plastics should be considered when bonding plastics. The higher content will seriously affect the UV transmittance, which will also have a significant impact on the curing efficiency of the glue, and even lead to the glue can not be cured;

8. Low viscosity products are recommended for large area bonding. If conditions are available, it is better to purchase vacuum equipment and fit it in vacuum environment to remove bubbles and improve the yield;

9. The above instructions are for reference only, and the specific operation needs to be adjusted by the customer according to the specific situation.
