How to use
1. When used, mix A and B components evenly, and then weigh A and B components according to proportion. Mix thoroughly and evenly with a clean stirring device in a clean container, and then potting can be done. It can also be sealed under a vacuum after removing the bubbles. 2. The surface of the potting element needs to be cleaned. If the potting product is too large, it is recommended to potting in stages and then cure at room temperature (4-12hr) or by heating (80ºC-0.5hr). 3. For the automatic potting production line, in order to ensure accurate mixing ratio of A and B, Part A and Part B should be vacuumed respectively to remove the bubbles (the foaming time is 5-10 minutes), and then A and B should be pumped to the static mixer in proportion with a metering pump, and then potting can be done after mixing evenly.
