Soft Shore A 25 Two Part Silicone Potting Gel with 10:1 Mix Ratio for Room Temperature Cure in Solar Inverters

HANAST HN-8808 A/B Soft Two Part Silicone Potting Gel

HN-8808 A/B is a soft, two-component condensation-cure (RTV-2) silicone potting gel supplied in a 10:1 ratio and formulated for solar inverter encapsulation and household appliance electronics protection. Mixed at 10:1 by weight, it cures at room temperature into a soft, stress-relieving transparent elastomer that cushions vibration and mechanical shock while insulating and moisture-sealing the assembly. The cured gel is non-toxic, odorless, non-corrosive and self-adhesive to metal and plastic substrates.

Key Features

• Soft stress-relief elastomer that absorbs vibration and cushions delicate components
• 10:1 mix ratio by weight with room temperature curing for easy, oven-free production
• Light formulation weighing less than water, reducing finished assembly mass
• High dielectric strength of 14 kV/mm or more for high-voltage isolation
• Wide operating temperature range from -50°C to 200°C for outdoor and thermal-cycling conditions
• Primerless adhesion to aluminium, iron, acrylic and PC plastics
• Non-toxic, odorless and non-corrosive curing, suitable for consumer appliance electronics
• Waterproof and moisture proof, protecting boards from humidity and condensation
• Small chemical shrinkage with no exotherm and no post-cure PCB warping
• RoHS and REACH compliant, supplied as a general chemical with SDS available
• 6 months shelf life with stable storage and easy shipping

Typical Applications

• Solar inverters: micro-inverter PCBs, string inverter control boards and MPPT charge controllers
• Household appliances: washing machine control boards, refrigerator inverter PCBs, air conditioner outdoor units and induction cooker power modules
• Smart home and IoT controllers requiring consumer-safe, non-toxic encapsulation
• Outdoor LED drivers, floodlight modules and street light power supplies
• Industrial equipment: motor controllers, power distribution boards and automation modules
• Aluminium substrate and general electronic encapsulation requiring transparent, waterproof insulation

FAQ

Q1: What is HN-8808 A/B and which applications does it suit?
A1: HN-8808 A/B is a soft 10:1 two-component room-temperature cure silicone potting gel. It is designed for solar inverter encapsulation (micro-inverters, string inverters, MPPT controllers) and household appliance electronics such as washing machine boards, refrigerator inverters, air conditioner outdoor units and induction cookers.

Q2: How soft is the cured gel and does it protect delicate components?
A2: The cured gel is a soft, stress-relieving Shore A 25 elastomer that absorbs vibration and mechanical shock and cushions thermal expansion stress, helping protect ceramic capacitors, fine-pitch SMD parts and flexible circuits.

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: Does it adhere without a primer and is it suitable for outdoor use?
A4: Yes. HN-8808 offers primerless adhesion to aluminium, iron, acrylic and PC plastic, and its wide -50°C to 200°C operating range and moisture resistance suit outdoor thermal cycling and humid conditions.

Q5: What certifications, MOQ and packaging are available?
A5: HN-8808 is RoHS and REACH compliant with an SDS available, and is classified as non-dangerous goods. It is supplied in 22kg/set or 11kg/set 10:1 kits, with wholesale and OEM/ODM bulk supply supported.
