Operation and use process
- Before sizing, stir A and B components evenly in their respective packages, because the filler may partially settle during storage.
- The A and B components are weighed at a ratio of 1:1, mixed evenly, and injected directly into the components (or modules) that need to be potting and protected. It is best to slowly inject along one side of the wall, which can reduce the generation of bubbles.
- The pot-sealed component is left to stand and let it bubble itself. After the bubble has basically disappeared, it can be heated and cured, or it can be cured directly at room temperature, which takes about 12hr.
- Please consult the Marketing Department of our company for the potting equipment that needs quantitative gluing.
