Core Positioning
IOTA GNJ 3250H high-temperature resistant two-component silicone gel features "medium-viscosity transparency + ultra-high temperature resistance", designed for potting protection of precision components such as IGBT modules, automotive electronic circuits, and solar cells under high-temperature conditions. With superior temperature resistance compared to ordinary silicone gels, combined with low hardness and low shrinkage, it builds a long-term moisture and corrosion barrier for microelectronic components.

Product Features: Dual Breakthroughs in High-Temperature Stability and Process Adaptability

• Wide Temperature Range, Excellent High-Temperature Performance: Operates stably at -60℃~250℃ for long-term use, with short-term temperature resistance up to 300℃, 50℃ higher than ordinary silicone gels; after high-temperature aging (200℃/1000 hours), tensile strength retention ＞85% and dielectric properties remain stable, suitable for high-temperature scenarios like engine compartments and power modules.
• Medium Viscosity for Easy Application, Flexible Curing Control: Two-component transparent liquid with medium viscosity (2000-4000mPa·s at 25℃) for good fluidity, filling complex structural gaps; supports room temperature curing (24h full cure) or high-temperature acceleration (120℃/1h) to meet different production rhythms.
• Non-Corrosive and No Precipitation, Safe and Reliable: No small molecule by-products released during curing, no silicone oil precipitation, non-corrosive to PCBA, metal pins, and sensor chips; volume resistivity ＞10¹⁴Ω·cm, dielectric strength ＞22kV/mm, meeting electronic component protection standards.
• Low Stress Protection, Strong Structural Compatibility: Shore 00 hardness 20-30, soft and compressible to absorb thermal cycle stress; shrinkage ＜0.2% to avoid structural damage to precision components, suitable for potting high-power devices like IGBTs and rectifier bridges.

Typical Applications

• Power Electronics: IGBT module potting passes 1000 thermal cycles (-40℃~150℃) without cracking, reducing module operating temperature by 10℃ and improving stability by 25%.
• Automotive Electronics: New energy vehicle motor controller potting ensures signal transmission error ＜0.5% under 150℃ continuous operation, meeting ISO 16750 automotive electronics reliability standards.
• New Energy: Solar inverter power module potting maintains insulation resistance retention ＞90% after 2000-hour 85℃/85%RH test, ensuring long-term stable operation of power generation systems.
