Operation process
1. Clean the surface: The surface of the object to be adhered to clean, remove rust, dust, moisture and oil.
2. Glue application: Cut the glue nozzle, put it into the glue gun, and squeeze the glue into the surface that has been cleaned up, so it is evenly distributed.
3. Adhesive sealing: 20 minutes after the glue application must be bonded, the adhesive surface will be fixed together.
4. Curing: room temperature curing for 24 hours to reach the highest strength.
Higher temperature in summer, curing will be faster; lower temperature in winter, curing will be slower.
Notes
Silicone rubber absorbs moisture and cures, unused rubber should be sealed and stored. Sealed storage in a cool dry place, storage period of 9 months.
