PRODUCT DESCRIPTION of Silicone Potting Glue
HN-8806, two-component addition type silicone potting rubber which can be cured into high-performance elastomer by room temperature or heating.
Product Features of Silicone Potting Glue
-
Excellent electrical properties and Thermal conductivity;
-
Flame retardant, high and low- temperature resistance from -50ºC to 250ºC (58°F to 432°F);
-
Aging resistance and moisture-proof;
-
Low shrinkage rate, will not release heat and by-products, no corrosion of potting components after curing;
- Protects components against thermal cycling stress and mechanical shock.

* UV-94 Fire retardant: After two times 10s burn tests on a 3mm-thick sample, the flame was extinguished within 30s, and no burnt fell. [1]
* Noted: The data after curing are all measured after the silicone is completely cured.
HOW TO USE Silicone Potting Glue
1. When used, weigh A and B according to proportion and then mix them evenly.
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.
