Product Description
10:1 Bulk Liquid Silicone Potting Gel HN-8808 Flame Retardant High Dielectric Strength for Power Module Electronics
10:1 Bulk Liquid Silicone Potting Gel HN-8808
Flame Retardant * High Dielectric 18-25 kV/mm * Soft 25A Gel for Power Electronics
HN-8808 is a bulk-packaged two-component room temperature curing silicone potting gel delivering industry-leading 18-25 kV/mm dielectric strength in a soft, stress-relieving 25 Shore A elastomer. The flame retardant formulation combined with an extended 1-2 hour pot life makes it the ideal material for high-volume PCB potting lines, power module encapsulation, and industrial electronic assembly where reliable insulation and production efficiency are paramount.
Key Features
⚡ 18-25 kV/mm Dielectric Strength
Exceptional breakdown voltage rating of 18-25 kV/mm provides a robust safety margin for high-voltage power modules, AC-DC converters, and industrial motor drive circuits. Combined with a low dielectric constant of 2.5-3.0 at 1 MHz, this compound minimizes signal loss in high-frequency switching applications.
???? Flame Retardant Protection
Engineered with inherent flame retardancy to prevent fire propagation in electronic assemblies. Suitable for consumer electronics, household appliances, and industrial control equipment that require enhanced fire safety compliance. Maintains flame retardant properties across the full -57°C to 250°C operating range.
???? Extended 1-2 Hour Pot Life
Unlike fast-cure formulations, HN-8808 offers a generous 1-2 hour working time at 25°C, enabling relaxed manual potting operations and accommodating larger batch mixing for automated dispensing lines. Cures fully in 8-12 hours at room temperature without oven post-cure.
???? Bulk Industrial Packaging
Supplied in 10kg/20kg Component A barrels with matching 1kg Component B containers optimized for 10:1 metering. Bulk packaging reduces per-unit packaging waste, lowers shipping cost per kilogram, and integrates seamlessly with production-floor dispensing stations. Multi-ton batch consistency guaranteed.
???? Ultra-Soft 25A Stress Relief
At just Shore A 25, HN-8808 is significantly softer than standard potting compounds, minimizing thermal expansion stress on delicate wire bonds, SMD solder joints, and ceramic capacitors. Ideal for densely populated PCBs where rigid encapsulation could cause component lifting or solder fatigue failure.
???? Wide Temperature Resilience
Maintains elastomeric integrity from -57°C to 250°C. Non-toxic, odorless condensation cure releases no corrosive by-products. Excellent adhesion to aluminum, iron, acrylic, and PC plastics provides reliable moisture sealing for outdoor and harsh environment electronics.
