Product Description
HN-8806 is a two-component addition-type silicone potting rubber
that can be cured into a high-performance elastomer at room
temperature or with heating. This potting silicone rubber offers
excellent electrical insulation, high moisture resistance, and a
wide operating temperature range of -50°C to 250°C. It is a
low-viscosity potting compound suitable for deep-section curing,
with low shrinkage after curing. It does not emit heat or
by-products, is non-corrosive to filled and sealed components, and
complies with RoHS standards. Its good thermal conductivity
effectively transfers heat generated by electronic components.
Applications
Widely used for potting and sealing electronic components, such as
various power modules, circuit boards, high-voltage transformers,
battery packs, fast-charging adapters, LED outdoor drive power
supplies, and other products. It provides flame retardancy,
environmental pollution resistance, vibration resistance, circuit
and component protection, waterproofing, and thermal conductivity,
making it ideal for moisture-proof protection in LED lamps.
Application Method
1.When using, mix components A and B evenly, then weigh them
according to the specified ratio. Thoroughly mix with a clean
stirring device in a clean container before potting. Vacuum sealing
can be applied after removing bubbles.
2.Clean the surface of the potting element. For large products, it
is recommended to pot in stages and then cure at room temperature
(4-12 hours) or by heating (80°C for 0.5 hours).
3.For automated potting production lines, to ensure accurate mixing
ratios of A and B, vacuum each component separately to remove
bubbles (foaming time is 5-10 minutes). Then, pump A and B to a
static mixer in proportion using a metering pump, and pot after
thorough mixing.
