IOTA GNJ 3250H is a high-temperature resistant silicone gel designed for high-heat electronic components, featuring medium viscosity, transparent two-component formulation, and room/high-temperature curing capability. With significantly improved heat resistance over standard silicone gels, it operates continuously at 200℃ (peak 250℃), offering low hardness (Shore 00 25±5), <0.3% shrinkage, corrosion-free performance, and no silicone oil bleeding—ideal for moisture/corrosion protection of IGBT modules, automotive electronics, and solar cells.

Key Performance Highlights

• Extreme Temperature Stability: Maintains elasticity >90% after 1000h/200℃ aging, with dielectric strength >22kV/mm across -60℃~200℃, solving high-temperature failure issues of conventional gels.
• Safe & Clean Curing: Room-temperature (25℃/24h) or high-temperature (80℃/1h) curing with <0.1% VOC, zero corrosion to PCBs/metal pins, UL94 V-0 certified.
• Low-Stress Protection: 0.5-1.0 MPa modulus buffers thermal stress from power cycles, protecting IGBT chips and extending module lifespan by over 30%.

Multi-Scenario Application Solutions

• IGBT Module Potting: Transparent for internal inspection, suitable for new energy vehicle motor controllers and industrial inverters, with 1000h stable operation at 150℃.
• Automotive Electronics: ECU/sensor potting achieves IPX7 waterproofing, vibration resistance (20-2000Hz), and passes AEC-Q100 Grade 2 reliability tests.
• Solar Battery Modules: PV junction box potting with <3% transmittance loss after 5000h UV aging, withstanding 1000 thermal cycles (-40℃~85℃) without cracking.
• High-Power Rectifiers: 0.35 W/(m·K) thermal conductivity aids heat dissipation, with insulation resistance >10¹⁴Ω·cm for short-circuit prevention.

Construction & Storage Advantages

• Easy Operation: 1:1 weight mixing ratio, no precise measurement needed; medium viscosity (3000-5000 mPa·s at 25℃) ensures flowability for 0.1-3mm gaps,fit automated lines.
• Stable Storage: 20kg sets (10kg A + 10kg B), 12-month shelf life at room temperature, >3-month post-opening life under 5℃ refrigeration, 95% material utilization.

IOTA GNJ 3250H redefines high-temperature electronic potting standards with "heat resistance + low stress + long life", empowering new energy, automotive electronics, and industrial control sectors to overcome extreme environment reliability challenges.
