01 Dec 2023
1. Issues that need to be paid attention to when using glue for bonding plastics and metals
1. The surface of the adherend should be clean and dry. Oil stains and other objects can be cleaned with gasoline solvent. Directly apply the glue evenly on the surface of the two adherends. Wait for 3-6 minutes. The two adherends will be aligned and bonded. Apply a little The pressure makes the bonding surface adhere more closely, and it can be left for a few hours, and the optimal bonding strength will be reached after 48 hours;
2. Materials with high bonding requirements such as metals and hard plastics can be roughened with iron sand and other materials. The effect of applying glue twice (wait a few minutes after the first application of glue before applying the second glue, let it dry and close it) is better. .
3. If there is rust, dust, oil, etc. on the metal surface, it can be polished, cleaned with industrial alcohol-based chemical solvents and dried before applying glue.
