Core Value
IOTA GNJ 3250 two-component addition-cured silicone gel features "1:1 mixing + medium-viscosity fluidity", designed for potting protection of precision electronic components such as automotive electronic circuits, solar cells, and IGBT modules. Transparent and soft with self-healing and low yellowing properties, it provides comprehensive protection against water, moisture, dust, shock, and insulation—ideal for long-term stable operation of complex electronic assemblies.

Product Features: Precise Balance of Protection Performance and Process Adaptability

• 1:1 Mixing, Easy Application：Two components mixed at 1:1 weight ratio, no complex measurement needed, suitable for manual or mechanical stirring; fully cures in 24 hours at room temperature, or 2 hours at 80℃, adapting to automated and manual potting, improving production efficiency by 35%.
• Addition-Cured, Safe and Reliable：No by-products released during curing, no silicone oil precipitation, non-corrosive to PCBA and metal pins; volume resistivity ＞10¹⁴Ω·cm, dielectric strength ＞20kV/mm, meeting electronic component protection standards.
• Medium Viscosity & Flow, Gapless Filling：Viscosity 2000-4000mPa·s (25℃) for good fluidity, quickly filling gaps in complex structures like sensors and rectifiers; excellent self-defoaming property ensures no bubble residue after potting, guaranteeing uniform protection.
• Transparent & Self-Healing, Strong Environmental Resistance：Light transmittance ＞93% (400-800nm), yellowing index ＜2 (1000-hour UV aging); Shore 00 hardness 15-25, soft and compressible with slight self-healing ability to absorb vibration impact; stable operation in -60℃~200℃ wide temperature range, no performance degradation after 1000-hour 85℃/85%RH test.

Typical Applications

• Automotive Electronics：ADAS controller potting meets IP6K9K standards, 12% faster signal response at -40℃ cold start, ensuring driving safety.
• New Energy：Solar junction box potting reduces power attenuation by 7% after 2000-hour UVB 313nm aging, extending service life.
• Power Electronics：IGBT module potting passes 1000 thermal cycles (-40℃~150℃) without cracking, reducing operating temperature by 8℃ and improving stability by 20%.
