Product Introduction
Momentive ECC3051S is a one-component, low viscosity silicone
conformal coating material that cures upon exposure to atmospheric
moisture to form a flexible protective coating. It achieves rapid
curing under ambient conditions without requiring specialized
equipment, and its tack-free time can be further accelerated with
mild heat exposure. This coating significantly reduces the
potential for corrosion in electronic components. Under specific
test conditions (based on 2016 comparative tests per IEC standards
for salt spray and mixed gas corrosion), it has demonstrated
superior corrosion prevention performance compared to other
polymers such as acrylics, polyurethane, polyolefin, and other
silicone polymers.
Enhanced Special Properties
- Fast Tack-free & Solvent-Free: 5-min tack-free time (100μm) with 100% solid content, eliminating
VOC emissions and environmental hazards.
- Enhanced Protection Certifications: UL94 V-0 flame retardancy (File E135148), compliant with
IEC60068-2-52 Severity 5 Salt Spray and IEC60068-2-60 Method 4
Mixed Gas Corrosion standards.
- Inspectability & Stability: UV tracer enables inspection under black light. Volume
resistivity of 1×10¹⁵ Ω·cm and ultra-low siloxane content (0.01%
D4-D10) minimize migration risks.
Application Scenarios
- High-Reliability Electronics: Ideal for conformal coating on automotive ECU boards and
industrial sensor PCBs, withstanding -45℃~200℃ thermal cycling and
salt spray environments.
- Outdoor Moisture Protection: Moisture-proof sealing for solar inverters and outdoor LED
drivers, certified by IPC-CC-830B for humidity resistance.
- Thin Section Potting: Local potting for inductors and connectors, with 2-min cure time
at 60°C accelerating production throughput.
