IOTA GNJ 3250 is a medium-viscosity two-component addition-curing silicone gel, designed for potting automotive electronics, solar cells, IGBT modules, and precision components. With 1:1 mixing ratio, by-product-free curing, and self-healing properties, it stands as a high-performance choice for precision electronics potting. Curing into a transparent soft elastomer (transmittance >95%, yellowing index <1 after 1000h UV aging), it combines electrical insulation and mechanical buffering, suitable for new energy, industrial control, and other harsh scenarios.

Key Performance Highlights

• Efficient & Safe Application: 1:1 weight mixing ratio enables easy use without precise measurement, adapting to automated and manual potting; addition-curing with no low-molecular by-products (VOC <0.1%), corrosion-free to PCB and metal pins, SGS certified. Medium viscosity (3000-5000 mPa·s at 25℃) ensures controlled flowability, filling component gaps (0.2-3mm) and self-leveling without bubbles in 5 minutes, improving potting efficiency.
• Rapid Curing & Wide Temperature Adaptability: 4h initial cure at 25℃, full cure in 24h; 30min at 80℃ for mass production. Wide temperature resistance (-60~200℃), >90% elasticity retention after 1000 thermal cycles (-40℃~125℃), dielectric strength >22kV/mm, volume resistivity >10¹⁴Ω·cm, ensuring stable operation in extreme environments.

Application Solutions

• Automotive Electronics Potting: Used for on-board radar, ECU modules with IPX7 waterproof rating, stable insulation in humid environments, resisting vibration and temperature shock, improving product reliability by over 30%.
• IGBT & Power Devices: Transparent softness allows visual inspection of internal components; self-healing function (scratch recovery <24h) reduces micro-crack risks, buffering thermal stress from power cycles and extending module lifespan.
• Solar Cells & Sensors: High transmittance ensures <5% power attenuation (5000h outdoor test), excellent yellowing resistance; sensor potting maintains sensitivity while isolating environmental interference.

Storage & Usage Advantages

Packaged as 20kg sets (10kg A + 10kg B), 12-month shelf life at room temperature, 95% material utilization with static mixing tubes. Low crosslink density (0.5-1.0 mmol/cm³) enables easy peeling after curing, excellent reworkability reducing maintenance costs.

IOTA GNJ 3250 integrates "efficient potting + self-healing protection + transparent weather resistance" to provide full-cycle protection for electronic components, enhancing product reliability and market competitiveness—especially suitable for new energy and automotive electronics requiring high potting efficiency and long-term stability.
