OEM Low-viscosity Silicone Potting Compound 1:1 for Electronics Insulation Waterproofing

SGS Certified Long Pot Life Silicone Potting Compound for Electronics Insulation

HN-8806 is a two-component 1:1 addition-cure RTV silicone potting rubber that cures into a high-performance elastomer at room temperature or with heating. With SGS certified quality, an extended 3-4 hours working time and excellent electrical insulation, this potting compound is ideal for potting and sealing electronic components such as circuit boards, power modules, high-voltage transformers, battery packs and fast-charging adapters.

Key Features

• Long Pot Life: Extended 3-4 hours working time at room temperature gives operators enough time for large-batch and complex potting jobs.
• Excellent Electrical Insulation: Dielectric strength 18-25 kV/mm and volume resistivity 1.0*10^16 Ω·cm protect electronics from leakage and short circuits.
• Waterproofing Electronics: Cured rubber seals components against water, moisture and humidity for long-term reliability.
• SGS Certified Quality: RoHS and SGS certified materials for safe export to global electronics markets.
• Wide Temperature Resistance: Stable performance from -50°C to 250°C for power and charging electronics.
• Component Safe: Low shrinkage rate, releases no heat or by-products and does not corrode potted components after curing.
• Color Options: Black, white, clear and grey, with clear grade allowing visual inspection of internal components.
• Easy 1:1 Mixing: Equal-weight ratio simplifies dispensing for both manual and automated potting lines.
