∎Attention of operation
1 .Don’t mix alcohol into the product, it will cause the product invalid. The tools with alcohol can’t be used before cleaning well.
2 .Avoid contact with eyes and skin. If contact with your skin, scrub first with soap water or alcohol, then rinse with water. If contact with your eyes, rinse with plenty of water and seek medical treatment immediately.
3. It is forbidden to build on the surface of the wet substrate.
4. Transportation: Avoid damp, high temperature, isolation, and rain, far away from heat, handle with care, and prohibit extrusion collision.
5. Tools Cleaning: It can be soaked in toluene or xylene. It is strictly forbidden to immerse in alcohol and other alcohol solvents. If it is not used for a long time, it should be cleaned immediately with alcohol or other organic solvents. The cured glue can only be scraped or torn off.
