IOTA GNJ 3450 is a two-component 1:1 addition-curing silicone gel, designed for potting IGBT modules, LED lamp shades, and automotive electronic 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 vehicles, 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. Low viscosity (800-1200 mPa·s at 25℃) ensures excellent flowability, filling micro gaps (0.1-2mm) and self-leveling without bubbles in 3 minutes, improving potting efficiency.
• Rapid Curing & Temperature Adaptability: 3h 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

• IGBT Module Potting: 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 by over 30%.
• LED Lamp Shade Protection: High transmittance ensures <5% light attenuation (5000h lighting test), excellent yellowing resistance, suitable for long-term outdoor LED lighting.
• Automotive Electronics: IPX7 waterproof rating, stable insulation in humid environments, ideal for potting automotive radar, ECU and other key components, resisting vibration and temperature shock.

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 3450 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.
