China Potting Compound Factory 10:1 Low Viscosity RTV Silicone Potting Compound for Sensor Automotive

HANAST HN-8808AB Low Viscosity RTV Silicone Potting Compound for Sensor and Automotive ECU

HN-8808AB is a low-viscosity, two-component condensation-cure RTV-2 silicone potting compound supplied in a 10:1 ratio. Produced by our China potting compound factory in Shenzhen, Guangdong, it flows readily into densely populated PCB assemblies and narrow sensor housings, then cures at room temperature into a transparent elastomer. The cured compound insulates, cushions vibration and forms a durable moisture barrier for sensors, automotive electronic modules and power converters.

Key Features

• Low viscosity for self-levelling flow into fine-pitch component gaps and sensor housings
• 10:1 mix ratio by weight with room temperature (RTV) curing, no oven required
• Good dielectric insulation with dielectric strength of 14 kV/mm or more
• Wide operating temperature range from -50°C to 200°C for automotive thermal cycling
• Vibration damping that reduces solder joint fatigue on ECU and sensor boards
• Neutral condensation cure, non-corrosive, non-toxic and odorless, releasing no by-products
• Small chemical shrinkage with no exotherm and no post-cure delamination
• Primerless adhesion to aluminium, iron, acrylic and PC plastic substrates
• Transparent cured elastomer for visual inspection of the potted assembly
• RoHS and REACH compliant, supplied as a general chemical with SDS available
• 6 months shelf life with stable storage and easy shipping

Typical Applications

• Automotive ECU modules: engine ECU, transmission TCU, BMS, ABS controller and ADAS camera modules
• Industrial sensors: pressure, proximity, Hall-effect sensors and temperature transducers
• Power converters and inverters: IGBT module potting, DC-DC converters and motor drive PCBs
• IoT and wireless devices: outdoor gateways, wireless sensor nodes, smart meters and GPS trackers
• Aluminium substrate and metal-housed power module potting requiring strong adhesion
• General electronic encapsulation requiring a transparent, waterproof and insulating protection

FAQ

Q1: What is HN-8808AB and which applications does it suit?
A1: HN-8808AB is a low-viscosity 10:1 two-part RTV silicone potting compound. It is used for industrial sensors, automotive ECU/TCU/BMS/ADAS modules, IGBT power converters and IoT device encapsulation.

Q2: Is the viscosity low enough for fine-pitch PCBs and small sensors?
A2: Yes. Its low mixed viscosity allows self-levelling flow into fine-pitch component gaps, under BGAs and into narrow sensor housings for void-free encapsulation.

Q3: What is the mix ratio and curing schedule?
A3: Mix Component A and Component B at a 10:1 ratio by weight. The compound cures at room temperature, with full cure in 8-24 hours at 25°C. After initial cure, gentle heating not exceeding 60°C may be used to accelerate curing.

Q4: Is it suitable for automotive use and is it non-corrosive?
A4: Yes. It withstands -50°C to 200°C thermal cycling, damps vibration and cures by a neutral condensation mechanism that is non-corrosive to copper traces and metal parts, making it suitable for under-hood and in-cabin electronic modules.

Q5: Where is it manufactured and what certifications, MOQ and packaging are available?
A5: It is manufactured in our China potting compound factory in Guangdong, Shenzhen. HN-8808AB is RoHS and REACH compliant with an SDS available and is classified as non-dangerous goods, supplied in 22kg/set or 11kg/set 10:1 kits with OEM/ODM bulk supply supported.
