PRODUCT DESCRIPTION
HN-8806, two-component addition type silicone potting rubber which can be cured into high-performance elastomer by room temperature or heating.
This potting silicone rubber has excellent electrical insulation, high moisture resistance, and a wide temperature range of -50°C to 250°C.
Low-viscosity potting compound that Will cure in deep sections. Low shrinkage rate after curing, will not emit heat and by-products, no corrosion for filling and sealing components.
No pollution in the surrounding environment, Complying with RoHs standards.
Its good thermal conductivity function can effectively transfer the heat emitted by the electronic components.
Product Features:

* 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
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.
