IOTA GNJ 3250N is a medium-viscosity transparent two-component silicone gel engineered for potting IGBT modules, automotive electronics, and solar cells. Its core advantage lies in ultra-low D3-D10 cyclic siloxane content (<0.1%, far below IEC 61249 standard), ensuring no silicone oil bleeding after curing. With low hardness (Shore 00 20±5) and <0.3% shrinkage, it provides corrosion-free, high-stability protection for sensitive microelectronics—ideal for high-end applications requiring strict cyclic residue control.
