Product Description

HN-8806A/B Multi-Industry Thermally Conductive Silicone Potting Compound

Hanast HN-8806A/B is a platinum-catalyst addition-cure silicone potting compound engineered for high-reliability electronics encapsulation. While standard compounds target generic power modules, HN-8806A/B extends coverage into electric vehicle battery systems, photovoltaic inverters, and 5G communication infrastructure where long-term durability and supply chain reliability matter most.

Key Differentiators vs. Standard Compounds

Selling Point	Competitor Gap	Hanast Advantage
Customizable Viscosity & Hardness	Most suppliers offer fixed formulations only	OEM/ODM adjustment of viscosity (1500-5000 mPa.s), Shore A hardness (35-55), pot life and cure speed per your process requirements
Full-Line Automation Compatibility	Limited guidance on pump parameters or mixer selection	Technical engineering support for dual-pump dispensing systems, static mixer optimization, and inline production calibration
EV & BESS Structural Grade Protection	Standard compounds lack vibration and shock spec validation	Shore A 45 elastomer provides structural cushioning validated for EV battery modules, motor controllers, and BMS assemblies under road vibration profiles
Photovoltaic Junction Box Endurance	Few competitors explicitly address PV junction box sealing	UV-stable, anti-yellowing formula resists outdoor weathering, moisture ingress, and thermal cycling across 25+ year PV system lifecycles

FAQ

Q1: Can you customize the viscosity for my automated dispensing line?: A1: Yes. Our lab team will adjust the filler content to target your specified viscosity range while maintaining thermal conductivity and electrical insulation targets.
Q2: How does the Shore A 45 elasticity benefit EV battery packs?: A2: The flexible cured elastomer absorbs mechanical stress from battery cell expansion during charge/discharge cycles and road-induced vibrations, preventing micro-cracks in solder joints.
Q3: Does this compound meet outdoor PV system certification requirements?: A3: The formulation is UV-stable and anti-yellowing, suitable for IP67-rated junction box sealing in commercial PV installations. Additional certifications available upon request.
Q4: What is the MOQ for OEM orders?: A4: Standard products require a minimum order of 1 kg for sample testing. Full-size drum orders start at 50 kg/set; OEM quantities follow mutual agreement with dedicated production scheduling.
Q5: What substrates bond well with this potting compound?: A5: Excellent adhesion to PCBs, metal heatsinks, glass, ceramics, and most plastics commonly used in electronics packaging without requiring primer.
