Core Value
IOTA GNJ 3250 two-component 1:1 addition-cured silicone gel features "medium-viscosity fluidity + self-healing protection", designed to provide waterproof, moisture-proof, dust-proof, shockproof and insulation protection for automotive electronic circuits, solar cells, IGBT modules and other precision components. Its transparent and soft properties ensure no stress damage to sensitive elements, making it ideal for long-term protection of complex electronic assemblies.

Product Features: Precise Balance of Performance and Process

• Easy Application, Efficient Curing: 1:1 mixing ratio for simple operation; medium viscosity (1500-3000mPa·s at 25℃) with good fluidity to quickly fill complex structural gaps; room temperature curing (24h full cure) or heat-accelerated curing (80℃/2h) compatible with automated potting lines.
• Addition-Cured, Safe and Non-Corrosive: No small molecule by-products released during curing, non-corrosive to PCBA, metal pins and other substrates; volume resistivity ＞10¹⁴Ω·cm, dielectric strength ＞22kV/mm, excellent insulation performance.
• Transparent Softness with Self-Healing Protection: Transmittance ≥95%, yellowing index ＜1 (1000-hour UV aging) without affecting optical performance of optoelectronic devices; Shore 00 hardness 20-30, soft and compressible with micro-crack self-healing ability to extend component service life.
• Excellent Environmental Resistance: Stable operation in -60℃~200℃ wide temperature range, no performance degradation after 1000-hour 85℃/85%RH test; UL94 V-0 flame retardancy to enhance device safety.

Typical Applications

• Automotive Electronics: ADAS control module potting meets IP67 standards, 12% faster signal response at -40℃ cold start, no structural damage after vibration test (10-2000Hz).
• New Energy: Solar junction box potting reduces module power attenuation by 5% after 1000-hour UVB 313nm aging test, ensuring long-term power generation efficiency.
• Power Electronics: IGBT module potting passes 1000 thermal cycles (-40℃~150℃) without cracking, reducing module operating temperature by 8℃ and improving stability by 20%.
