Core Value
IOTA GNJ 3450 two-component addition-cured silicone gel features "1:1 mixing + self-healing properties", designed for potting protection of precision electronic components such as IGBT modules, LED lampshades, and automotive electronics. Low viscosity and fast curing adapt to complex structure potting, while transparent and soft texture combines high light transmittance and low yellowing, making it ideal for balancing protection performance and optical requirements.

Product Features: Dual Advantages of Efficient Potting and Long-Term Protection

• 1:1 Mixing, Easy Application：Two components mixed at 1:1 weight ratio, no precise measurement needed, suitable for manual or mechanical stirring; fully cures in 24 hours at room temperature, or 1.5 hours at 80℃, improving production efficiency by 30% and adapting to automated potting lines.
• Addition-Cured, Safe and Eco-Friendly：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.
• Low Viscosity & High Flow, Gapless Filling：Viscosity as low as 800-1500mPa·s (25℃), quickly penetrating fine gaps to fill complex structures like LED lampshades and IGBT modules; excellent self-defoaming property ensures no bubble residue after potting, guaranteeing uniform heat dissipation and insulation.
• Transparent & Self-Healing, Optical and Durable：Light transmittance ＞94% (400-800nm), yellowing index ＜1 (1000-hour UV aging), without affecting LED color rendering; Shore 00 hardness 20-30, soft and compressible with slight self-healing ability to absorb thermal cycle stress and extend component service life.

Typical Applications

• Power Electronics：IGBT module potting passes 1000 thermal cycles (-40℃~150℃) without cracking, reducing operating temperature by 10℃ and improving electrical stability by 20%.
• LED Lighting：LED lampshade potting increases light transmission uniformity by 15%, color temperature deviation ＜50K, no atomization or yellowing after long-term use, meeting indoor and outdoor lighting optical requirements.
• Automotive Electronics：Vehicle radar sensor potting ensures signal transmission error ＜0.3% after vibration test (10-2000Hz), adapting to high-temperature and high-humidity engine compartment environment.
