Core Value
IOTA GNJ 3250N two-component silicone gel features "ultra-low D3~D10 cyclic content" as its core advantage, designed for potting protection of precision electronic components 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 electronic assemblies with strict cyclic content requirements.

Product Features: Dual Assurance of Low Cyclic Content and Protection Performance

• Medium-Viscosity Two-Component, Flexible Application：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 heat-accelerated curing (80℃/2h), adapting to automated lines and small-batch production.
• Ultra-Low Cyclic Content, Clean Protection：D3~D10 cyclic content is much lower than industry standards, no low-molecular silicone oil precipitation during curing, avoiding contamination of PCBA and metal pins; volume resistivity ＞10¹⁴Ω·cm, dielectric strength ＞20kV/mm, meeting protection requirements for precision electronic components.
• Low Hardness & Low Shrinkage, Stress Buffering：Shore 00 hardness 15-25 after curing, soft and compressible to absorb vibration impact; shrinkage ＜0.3% to avoid structural stress on precision components like sensors and rectifier bridges, ensuring long-term component stability.
• Chemically Stable, Strong Environmental Adaptability：Stable operation in -60℃~200℃ range, no performance degradation after 1000-hour 85℃/85%RH test; non-corrosive, compatible with glass, metal, plastic and other substrates, ensuring no corrosion risk for potted assemblies.

Typical Applications

• Power Electronics：IGBT module potting shows cyclic precipitation ＜0.1% after 1000-hour high-temperature aging (150℃), reducing electrical performance attenuation by 12%, meeting strict low-volatile requirements of high-end electronic equipment.
• Automotive Electronics：ADAS ECU module potting passes 1000 cycles of -40℃~125℃ thermal shock without delamination, with signal transmission stability better than traditional silicone gels, adapting to automotive-grade reliability standards.
• New Energy：Solar junction box potting reduces power attenuation by 7% after 2000-hour UVB 313nm aging, with cyclic migration meeting RoHS 2.0 limits for the photovoltaic industry.
