Core Value
IOTA GNJ 3250LC two-component silicone gel features "medium-viscosity transparency + by-product-free curing", designed for potting protection of precision microelectronic components such as automotive electronic circuits, solar battery modules, and sensors. Low hardness and wide temperature range ensure stress-free protection for sensitive elements, while no small molecule precipitation and weathering resistance guarantee long-term reliable operation—ideal for moisture and corrosion protection of complex electronic assemblies.

Product Features: Dual Advantages of Protection Performance and Process Adaptability

• Medium-Viscosity Two-Component, Flexible Application：Mixed at 1:1 weight ratio, medium viscosity (2000-4000mPa·s at 25℃) for moderate fluidity, suitable for manual or mechanical potting; supports room temperature curing (24h full cure) or heat-accelerated curing (80℃/2h), adapting to automated lines and small-batch production.
• By-Product-Free Curing, Clean Protection：Addition curing with no small molecule release or silicone oil precipitation, non-corrosive to PCBA and metal pins; volume resistivity ＞10¹⁴Ω·cm, dielectric strength ＞20kV/mm, meeting electronic component protection standards.
• Low Hardness & Low Shrinkage, Stress Buffering：Shore 00 hardness 15-25 after curing, soft and compressible to absorb vibration impact; shrinkage ＜0.3% to avoid structural stress on precision components like sensors and smart water meters.
• Wide Temperature & Weather Resistance, Strong Environmental Adaptability：Stable operation in -60℃~200℃ range, no performance degradation after 1000-hour 85℃/85%RH test; excellent damping performance reduces poor contact risk of automotive electronic circuits caused by vibration.

Typical Applications

• Automotive Electronics：New energy vehicle BMS module potting passes 1000 thermal cycles (-40℃~125℃) without cracking, improving signal transmission stability by 18%.
• New Energy：Solar junction box potting reduces power attenuation by 6% after 2000-hour UVB 313nm aging, ensuring stable long-term power generation efficiency.
• Industrial Sensing：Smart water meter sensor potting remains mold-free and short-circuit-free after 2 years in humid environments, with measurement accuracy error ＜0.5%, better than traditional potting materials.
