Usage Guidelines
1. Clean the surface, clean the surface of the adhered or coated object, and remove rust, dust, oil, etc.
2. Mixing glue: It is recommended to use the matching glue gun. First, use the glue gun to mix the AB component until the glue is flush, then install the mixing nozzle and start to glue until the glue is evenly mixed. It is recommended to discard the first 2~3 tubes of glue. .
3. Apply glue: Choose a suitable scraper and apply the mixed glue to the surface to be repaired, ensuring that the surface to be glued is completely infiltrated by the glue.
4. Assembly (pressing): After gluing, complete assembly (pressing) within the operable time.
5. Curing: This product is cured at room temperature according to the time specified in the above "Curing Performance" data. When the temperature is lower than 25℃, the curing time should be appropriately extended. Heating and curing can improve the performance.
6. Post-processing: After curing for a certain period of time, traditional machining methods such as turning, grinding, drilling, tapping, etc. can be used to achieve the required size.
Storage method and shelf life
Store sealed in a cool, dry place away from light. The shelf life is 12 months at 5-28℃.
Precautions
This product is a safe and non-toxic substance after curing, but before curing, contact with the skin should be avoided as much as possible. If it accidentally splashes into the eyes, rinse quickly with plenty of water. Detailed safety data can be found in the Product Safety Data Sheet.
