Product Overview
Our Electronic Potting, also called transparent electronic glue or power encapsulation silicone, is a professional Silicone Encapsulant specially engineered for railway traction control units—the core component ensuring stable traction power supply and safe operation of trains. As a professional supplier of High transparency mold silicone and industrial silicone solutions, we optimize this product for railway scenarios: it is a dual-component liquid silicone with high transparency, solvent-free and environmentally friendly. It has excellent fluidity, can fill tiny gaps of traction control components, cures quickly and deeply, and its high transmittance allows visual inspection of internal components, while providing reliable insulation, anti-vibration and anti-ultraviolet protection. Technical Specifications
Our Electronic Potting has stable performance, with HY-9320 as a typical model (customizable parameters): dual-component Addition Curing Silicone, A/B weight ratio 1:1, colorless transparent liquid appearance, viscosity 500±100 mPa.s (each component). After curing, hardness is 20±3 Shore A, refractive index 1.41, transmittance 95% (450nm, 2mm), volume resistivity 1.0×1015 Ω.cm, thermal expansion coefficient 280 ppm/℃. It can be used for a long time at -50℃ to 250℃, cures quickly with adjustable speed via temperature. Shelf life is 12 months (cool and dry storage), non-hazardous for transportation; A/B components need sealed storage to avoid moisture contact.
