China EMI Shielding Sealant Suppliers - Silver Filled Epoxy with >60dB Shielding Effectiveness for Airborne Radar Systems Factory
Product Introduction
Gaps along enclosure mating lines allow external EMI noise to disrupt sensitive circuits while letting humid air and dust penetrate devices. As an electrically conductive epoxy, it addresses both threats in a single application, eliminating leakage paths that traditional mechanical gaskets fail to seal.
Songxi Technology EMI Shielding Sealant is engineered to eliminate these gaps. Its singlecomponent system features a highpolymer matrix loaded with submicron conductive particles. Upon heatcuring, it transforms into a conductive elastomeric gasket with exceptionally low volume resistivity. This silver epoxy adhesive establishes an uninterrupted electrical path across housing interfaces, ensuring ultrahigh shielding over a broad frequency spectrum.
For automated production, this sealant eliminates manual gasket placement. Its optimized rheology allows smooth dispensing through automated systems without stringing or clogging. The singlecomponent formulation removes premixing, human error, and waste.
In the field, durability determines lifetime. As a high temperature silicone gasket sealant, it withstands salt spray and high operating temperatures. The anticorrosion binder prevents phase separation and interface corrosion, retaining shielding integrity for years.
Through thermal shocks from -40°C to 125°C and structural vibrations, this high temp conductive epoxy remains flexible. Its resilient structure absorbs mismatched thermal expansion between metal and plastic, resisting cracking and delamination to safeguard communication, aerospace, and automotive systems.
