Product Overview

ECC3050S is a low-viscosity, solventless silicone conformal coating that cures rapidly at room temperature to a soft, transparent rubber. It offers efficient protection for printed circuit board assemblies (PCBA) with tack-free time as short as 5 minutes. Optimized for spray or flow coating, its oven cure capability (≤60°C) reduces handling time to 2 minutes, making it ideal for high-volume production with temperature-limited components.

Key Advanced Features

  • Flame Retardancy: UL94V-0 certified (File No. E135148) to suppress flame propagation during electrical faults.
  • Low Stress: Low modulus (22 Shore A) minimizes CTE stress on sensitive components during thermal cycling.
  • Moisture Resistance: Superior adhesion ensures long-term humidity protection with ultra-low siloxane content (0.01 wt%) to prevent electrochemical migration.

Applications

  • Protects BGA chips and microprocessors in automotive ECUs against vibration, condensation, and chemicals per ISO 16750-4.
  • Ensures signal stability for MEMS sensor solder joints in harsh environments (85°C/85% RH).
  • Prevents arcing in high-voltage LED drivers while maintaining thermal management capability.
