RTV Two Component Thermal Conductive Waterproof Silicone Potting HN-8808
Shockproof Coating • Custom OEM • RoHS Compliant
HN-8808 is an RTV two-component thermal conductive waterproof silicone potting compound delivering 0.1-0.20 W/m·K thermal conductivity with IP67-equivalent moisture sealing in a flexible Shore A 25 gel. Its shockproof and vibration-damping properties provide robust mechanical protection for PCB assemblies in high-shock environments. Full custom OEM formulation service: viscosity, hardness, color, and cure profile tailored to your production line. RoHS and REACH compliant for global market access.
Key Features
Thermal Conductivity
Thermal conductivity of 0.1-0.20 W/m·K provides a reliable heat dissipation path from PCB components to the enclosure, reducing hot-spot temperatures in enclosed electronics. While not a high-conductivity TIM, this thermal pathway effectively spreads heat in convection-limited sealed assemblies.
IP67 Waterproof Sealing
Creates a continuous moisture barrier with ≥1*1014 Ω·cm volume resistivity that maintains electrical isolation even after prolonged water immersion. Ideal for outdoor-rated electronics, marine equipment, bathroom appliances, and wash-down industrial controls.
Shockproof & Vibration Damping
The soft 25 Shore A gel elastomer absorbs mechanical shock and dampens vibration across a broad frequency spectrum. Protects solder joints, ceramic capacitors, and connector interfaces from fatigue failure in portable power tools, vacuum cleaners, power washers, and automotive under-hood modules.
Full Custom OEM Service
Complete formulation flexibility: adjust viscosity (thinner for deep penetration or thicker for vertical hold), hardness (softer for stress relief or firmer for mechanical support), color (transparent, white, grey), and cure profile. Samples in 3-5 working days. 40,000 m² ISO 9001 facility.
RoHS & REACH Global Compliance
100% RoHS and REACH compliant with no restricted substances. Non-toxic, odorless condensation cure meets consumer product safety standards for household appliances, medical device peripherals, and children's electronic products. Full compliance documentation provided with every batch.
Multi-Substrate Strong Adhesion
Bonds directly to metals (aluminum, iron, copper) and plastics (acrylic, PC, ABS) without primer. Enhances overall waterproof sealing by eliminating moisture wicking paths at the potting-to-housing interface. Maintains adhesion through -57°C freeze-thaw and 250°C bake cycles.
