Application
- Automotive electronics, modules
- LED power drive module
- Solar module junction box
- Electric vehicle charging column module
- Lithium battery pack, capacitor pack
- Magnetic induction coil
- Inverter power supply
Operation process
- Before use, stir components A and B evenly in their respective packages, because the filler may partially settle during the storage process.
- Weigh the components A and B at A ratio of 1:1, mix them evenly, and directly inject them into the components (or modules). It is best to inject slowly along the side of the wall to reduce the generation of bubbles.
- After the bubbles disappear, it can be solidified by heating or directly solidified at room temperature, which takes about 8
