How to use Supex 4005 Electronics Silicone
- Clean the surface: clean the surface of the substrate, remove rust, dust and
- Gluing: Squeeze the product onto the cleaned substrate
- Curing: Cure from the surface to the inside. After curing for 24 hours at 25 ℃ and 55% relative humidity, the curing depth of the glue is 2~4mm, and the curing depth gradually increases with the extension of time.
Note:
- Curing requires humid air, which may take a long time in the case of large bonding
- After the operation is done, tighten the cap immediately and store the unused glue. When used again, if there is a little crust at the nozzle, it can be removed without affecting normal
- Avoid contact with eyes, skin and clothing. Rinse with soapy water immediately after skin If it spills into your eyes, rinse immediately with plenty of water. If you still feel unwell, go to the hospital for examination.
- If the dispenser is used for operation, it is recommended to soak the dispenser needle in a container containing silicone oil when the operation is over or interrupted to prevent curing and clog the needle, and remove a small amount of glue in the needle when working.
