Ultra Soft 1:1 Mix Ratio Waterproof Electronic Potting Silicone Gel for Circuit Boards and LEDs

HANAST HN-6607 Ultra Soft Electronic Potting Silicone Gel

HN-6607 A/B is an ultra soft, low crosslink density two component silicone gel engineered for stress free encapsulation of delicate electronic components. Before cure it is a low viscosity transparent liquid that flows easily into tight gaps; after cure it forms a self healing, repairable gel delivering outstanding dielectric insulation over a wide temperature and humidity range.

Key Features

• Ultra soft, low modulus gel for stress free, low stress protection of sensitive components
• Low viscosity 300-500 mPa·s for easy flow, self leveling and deep penetration
• Two component addition cure with convenient 1:1 mix ratio by weight and deep section cure
• Excellent dielectric insulation: 2.8-3.2 kV/mm dielectric strength
• Wide temperature range -60°C to 200°C, humidity and moisture resistant
• Long pot life and working time of 120-180 minutes at 25°C for volume production lines
• Low shrinkage, no by-products, dimensionally stable cure
• Repairable, reworkable and self healing for easy removal and rework
• Non-toxic, non-corrosive, solvent free and halogen free
• RoHS and REACH compliant for EU export

Typical Applications

• ECU and automotive electronics protective potting and encapsulation
• PCB and circuit board conformal protection and waterproofing
• LED driver, LED display and HID module encapsulation
• Pressure sensor, load cell and precision sensor potting
• IGBT power module and power electronics encapsulation
• EV battery, BMS and battery cell encapsulation
• Solar / photovoltaic junction box potting
• Sensors and precision devices sensitive to mechanical stress
