EMI Shielding Sealant from China Suppliers - Silver Filled Epoxy with 60dB Effectiveness for Radar Systems
Product Introduction
Features
Delivers exceptional electromagnetic shielding over a broad frequency spectrum via optimized micron conductive fillers.
Eliminates complex mixing ratios, providing easy handling with rapid thermal cure acceleration for uniform properties.
Establishes a low volume-resistivity, unbroken electrical path across complex enclosure seams to prevent EMI leakage.
Forms a dense elastomeric barrier that blocks moisture, dust, and salt spray, preventing galvanic interface corrosion.
Perfectly tailored for automated precision dot-dispensing and robotic trace layout without stringing or tailing.
Application
Frequently Asked Questions
It is primarily applied in automated form-in-place conductive gasketing, EMI shielding, and environmental sealing for high-frequency communication modules, drone flight controllers, automotive radar housings, and rugged electronic enclosures.
The single-component formulation eliminates the need for premixing, preventing human error and material waste. Its tailored rheology allows smooth dispensing through automated robotic systems without stringing, tailing, or nozzle clogging.
The sealant withstands thermal shocks across a wide temperature range from -40°C to 125°C while remaining flexible and resistant to structural vibrations.
It forms a dense elastomeric barrier that blocks moisture, dust, and salt spray. Additionally, an anticorrosion binder prevents phase separation and galvanic interface corrosion, preserving shielding integrity over years of service.
Yes, its resilient cured structure absorbs mismatched thermal expansion between metal and plastic substrates, preventing cracking and delamination.
The polymer matrix is loaded with submicron conductive silver particles. Upon heat-curing, it forms a continuous low volume-resistivity electrical path across housing seams to block electromagnetic interference over a wide frequency band.
