Product Description:
DX326B It is a single component, high viscosity structural adhesive. Under exposure to ultraviolet light, heating, or the use of surface activators that lack oxygen, the product will cure. After curing, the product has excellent flexibility and strength, making it highly resistant to vibration and impact.
Typical application:
DX326B is mainly used for bonding, sealing, or coating metal and glass components, for reinforcing printed circuit boards, and for bonding various materials.

Instructions for use:
1. This product has photosensitivity. When storing, it should be kept away from sunlight, ultraviolet rays, and artificial light sources.
2. The product should be coated with black rubber hose.
3. achieve the best bonding performance, the surface of the material being bonded should be clean and free of oil esters.
4. The curing depth depends on the intensity of the light source, the distance from the light source, the bonding gap, and the transmittance of the material.
5. For temperature sensitive substrates, such as thermoplastic, cooling is required.
6. Crystalline and semi crystalline thermoplastic materials need to be checked for stress cracking caused by contact adhesive.
7. Excessive uncured adhesive can be wiped away by organic solvents (such as acetone).
8. Adhesive components should be cooled before bearing any load.
Precautions:
Keep away from children.
It is recommended to use it in a well ventilated area.
If it accidentally comes into contact with the skin, wipe it first and then rinse it with clean water.
If it accidentally comes into contact with the eyes, immediately rinse with clean water and go to the hospital for examination.
