Core Value
IOTA GNJ 3250H high-temperature resistant two-component silicone gel features "ultra-high temperature resistance + low-stress protection", designed for potting protection of precision electronic components under high-temperature conditions such as IGBT modules, automotive electronic circuits, and solar cells. Medium-viscosity transparency adapts to complex structure potting, while no low-molecular precipitation and chemical stability ensure long-term reliable operation—ideal for solving electronic component protection challenges in high-temperature environments.

Product Features: Dual Breakthroughs in High-Temperature Resistance and Protection Performance

• Medium-Viscosity Two-Component, Flexible Curing：Mixed at 1:1 weight ratio, medium viscosity (2000-4000mPa·s at 25℃) for moderate fluidity, suitable for manual or mechanical potting; supports room temperature curing (24h full cure) or high-temperature acceleration (120℃/1h), adapting to different production rhythms.
• Ultra-High Temperature Resistance, Wide Temperature Stability：Superior high-temperature resistance compared to ordinary silicone gels, stable operation in -60℃~250℃ range, short-term temperature resistance up to 300℃; after 1000-hour 200℃ thermal aging test, hardness change rate ＜10%, insulation performance retention ＞90%.
• Low Hardness & Non-Corrosive, Stress Buffering：Shore 00 hardness 15-25 after curing, soft and compressible to absorb thermal cycle stress; shrinkage ＜0.3%, no low-molecular silicone oil precipitation, non-corrosive to PCBA and metal pins, protecting sensitive components like sensors from damage.
• Chemically Stable, Long-Term Protection：Volume resistivity ＞10¹⁴Ω·cm, dielectric strength ＞20kV/mm, excellent insulation performance; no cracking or mold after 1000-hour 85℃/85%RH test, reliably protecting microelectronic components from moisture and corrosion.

Typical Applications

• Power Electronics：IGBT module potting operates continuously at 200℃ for 500 hours, reducing junction temperature by 12℃, electrical performance attenuation ＜5%, meeting high-temperature requirements of new energy vehicle inverters.
• Automotive Electronics：Engine compartment ECU module potting passes ISO 16750 high-temperature aging test, no delamination after 1000 cycles of -40℃~150℃ thermal shock, stable signal response speed.
• New Energy：Solar combiner box potting reduces power attenuation by 8% after 2000-hour UVB 313nm aging, adapting to high-temperature and strong ultraviolet environments in desert areas.
