Instructions for UV adhesive shadowless adhesive

guidelines for use of shadowless adhesive

1 Clean and dry the bonded surface without grease

2. Apply UV adhesive to one of the surfaces, close the two planes, and irradiate with an ultraviolet lamp with appropriate wavelength (usually 365nm) and energy or a high-pressure mercury lamp for illumination. The illumination shall be from the center to the periphery, and confirm that the light can indeed penetrate to the bonding part

3. It is recommended to light for about 6S. During initial positioning, remove the remaining glue on the workpiece and then re light it until it is completely cured

4. The curing time shall be different according to different war preparation materials, adhesive thickness and UV intensity. It is recommended that the user purchase an ultraviolet intensity tester and conduct light intensity test before bonding to reduce the scrap rate

5. Temperature also has a little effect on the activity of the glue. When the temperature is low, the curing time should be appropriately extended

6. During operation, do not squeeze or repeatedly rub the materials to be bonded, and it is recommended to use fixed tools

7. During the bonding of plastics, the ultraviolet absorption in the plastics should be considered, while the relevant personnel of chemical manufacturers often use figures to quantitatively introduce the characteristics of materials and the content of physical collectors. The high content will seriously affect the ultraviolet transmission rate, thus also have a significant impact on the curing efficiency of the glue, and even make the glue unable to cure

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

but its implementation needs to be strengthened 9 The above instructions are only for reference. In particular, it is not only necessary to carry out fundamental transformation from the plastic granulator process, but also the customer needs to make appropriate adjustment according to the specific situation, and dismantle and install the bending resistance under the beam.
