Core Positioning
IOTA GNJ 3450 two-component 1:1 addition-cured silicone gel features "by-product-free curing + self-healing property", designed for transparent protection of IGBT modules, LED lamp shades, automotive electronics and other precision components. Combining low viscosity and fast curing, it balances process efficiency and long-term reliability, making it ideal for electronic potting applications.

Product Features: Dual Advantages of Performance and Process

• Easy Application, Efficient Curing: 1:1 mixing ratio for simple operation; 4-hour initial cure at room temperature (full cure in 24h), heat curing at 80℃ reduces time to within 1 hour, suitable for automated potting lines; addition-cured with no small molecule by-products, non-corrosive to components.
• Low-Viscosity Self-Leveling, Bubble-Free Filling: Viscosity as low as 800-1500mPa·s (25℃) for rapid penetration into complex structural gaps; curing shrinkage ＜0.2% to avoid stress damage to precision components.
• Transparent Softness with Self-Healing Protection: Transmittance ≥95%, yellowing index ＜1 (1000-hour UV aging) without affecting LED lamp shade optics; Shore 00 hardness 20-30, soft and compressible with micro-damage self-healing ability to extend component service life.
• Excellent Environmental Resistance: Stable operation in -60℃~200℃ wide temperature range, no performance degradation after 500-hour 85℃/85%RH test; volume resistivity ＞10¹⁴Ω·cm, dielectric strength ＞22kV/mm, meeting electronic insulation requirements.

Typical Applications

• Power Electronics: IGBT module potting passes 1000 thermal cycles (-40℃~150℃) without cracking, reducing module operating temperature by 8℃ and improving stability by 20%.
• LED Lighting: Lamp shade potting maintains ＞98% transmittance, color temperature deviation ＜50K, no fogging or yellowing after long-term use, enhancing lamp efficiency and lifespan.
• Automotive Electronics: Vehicle ECU controller potting meets IP67 dust/waterproof standards, signal transmission error ＜0.3% after vibration test (10-2000Hz), ensuring driving safety.
