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.

One hour Fast-curing;
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;
- Flexible Rubber – 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
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.
