In an era where automotive electronics, new energy, and optoelectronic devices demand increasingly stringent reliability, IOTA GNJ 3250 Two-Component 1:1 Addition-Curable Silicone Gel stands out as the benchmark choice for electronic component potting, combining "high-efficiency protection + easy application" advantages. This medium-viscosity transparent gel features a 1:1 mixing ratio, enabling uniform blending without complex计量, and supports room-temperature (24h) or heat-accelerated (80℃/2h) curing, fundamentally improving production line efficiency. After curing, it forms a soft elastomer with self-healing properties and high light transmittance (≥95%), perfectly suited for long-term protection of high-precision components like IGBT modules and sensors.

Key Advantages: Building a Comprehensive Barrier for Electronic Components

• Addition-Curing, Zero Contamination Risk：Cures via hydrosilylation reaction with no small-molecule by-products, avoiding electrode corrosion or short circuits caused by volatile substances in traditional condensation-type materials, meeting the strict ISO 16232-10 standard for automotive electronics.
• Medium Viscosity Flowability, Full Coverage of Complex Structures：Viscosity controlled at 5000-8000 mPa·s, enabling deep penetration into 0.1mm fine gaps, perfectly filling complex structures such as IGBT module pins and sensor circuit boards for "dead-angle-free" potting.
• Wide Temperature Stability & Self-Healing Ability：Operates stably at -50℃ to 200℃ without embrittlement, maintaining excellent elasticity (Shore 00 30-40) under extreme conditions like automotive engine compartment vibration and photovoltaic power station temperature cycles; minor mechanical scratches self-repair via molecular chain reorganization, extending protection life by over 30%.
• Optical-Grade Transparency & Yellowing Resistance：Transmittance over 95% without affecting optoelectronic signal transmission; UV-resistant additives ensure no yellowing (ΔE＜1.5) after 1000 hours of QUV aging test, meeting appearance requirements for LED lampshades and display modules.

Precisely Adapted to Multi-Field Potting Needs

• Automotive Electronics：ECU control modules and radar sensors pass IP6K9K dustproof and waterproof certification after potting, with no performance degradation after 2000 cycles of -40℃~125℃ thermal shock.
• New Energy Sector：Potting for solar inverter IGBTs, with dielectric strength ＞25kV/mm and volume resistivity ＞10¹⁵Ω·cm, effectively suppressing partial discharge and improving power station safety.
• Industrial & Optoelectronic Equipment：Encapsulation of high-power rectifiers and laser diodes, ensuring no stress damage after curing and stable signal transmission of precision components in dusty, humid environments.
