10:1 Two Part Silicone Potting Gel HN-8808 Soft 25A RT Cure for Solar Inverter Household Appliance Protection

Product Overview

HN-8808 is a soft 25 Shore A two-component silicone potting gel formulated for solar inverter encapsulation and household appliance electronic protection. Its exceptionally low 0.98 specific gravity reduces weight in finished assemblies, while the 1-2 hour pot life and ambient-temperature 8-12 hour full cure provide hassle-free production integration. Non-toxic, odorless, and self-adhesive to metal, acrylic, and PC substrates—the complete solution for consumer and renewable energy electronics.

Key Features

Solar Inverter Optimized

Engineered for photovoltaic micro-inverter and string inverter PCB encapsulation
Withstands outdoor thermal cycling (-57°C to 250°C), UV exposure, and humidity without degradation
18-25 kV/mm dielectric strength provides reliable isolation in high-voltage DC bus circuits up to 1500V systems
Non-corrosive to copper traces and aluminum heatsinks

Household Appliance Protection

Ideal for waterproof sealing and insulation protection of washing machine control boards, refrigerator inverter PCBs, air conditioner outdoor units, induction cooker power modules, and smart home IoT controllers
Non-toxic and odorless cure ensures consumer safety compliance for in-home applications

Ultra-Light 0.98 Specific Gravity

At just 0.98 g/cm³, HN-8808 is lighter than water and significantly lighter than standard potting compounds (typically 1.2-1.6)
Translates to lower shipping weight, reduced assembly mass, and cost savings on high-volume production
Particularly advantageous for portable appliances and weight-sensitive drone/aerospace electronics

Soft 25A Stress-Free Encapsulation

Shore A 25 hardness delivers a compliant, gel-like elastomer that absorbs vibration, dampens mechanical shock, and eliminates thermal expansion stress on delicate components
Zero post-cure shrinkage prevents PCB warping
Ideal for flexible circuits, ceramic capacitors, and fine-pitch SMD assemblies

Extended Working Time

1-2 hour pot life at 25°C enables relaxed manual potting of large or complex PCB assemblies
Full cure in 8-12 hours at ambient temperature—no oven, no post-baking required
Adjustable cure speed by varying the B component ratio to match your production cadence

Multi-Substrate Adhesion

Primerless adhesion to aluminum, iron, acrylic, and PC plastic substrates ensures robust waterproof sealing without additional surface treatment
The non-swelling, non-corrosive formulation preserves dimensional stability of plastic housings and maintains bond integrity under thermal cycling and humidity exposure

Target Applications

Application	Use Case	Key Benefit
Solar Inverters	Micro-inverter PCBs, string inverter control boards, MPPT charge controllers	18-25 kV/mm isolation, -57°C~250°C outdoor rating, 0.98 lightweight
Household Appliances	Washing machine controllers, refrigerator inverters, A/C outdoor units, induction cookers	Non-toxic, odorless, moisture-proof, consumer-safe compliance
LED Lighting	Outdoor LED drivers, floodlight modules, street light power supplies	Weatherproof sealing, UV-stable elastomer, soft stress relief
Industrial Equipment	Motor controllers, power distribution boards, automation modules	Anti-vibration damping, anti-fouling coating, shockproof protection
