China Manufacturer Potting Material Flexible Silicone Sealant 1:1
Thermally Conductive 2 Part Silicone Adhesive Electronic Component
For Power Modules battery Packs Fast-charging Adapters
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.
Product Features:
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.

* 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.
