ECC3050S conformal coating is a low viscosity, solventless silicone coating that cures very rapidly, at room temperature, to a soft, transparent silicone rubber. ECC3050S conformal coating can also be cured using a low-temperature oven process to reduce cure and handling times, making it an excellent candidate to consider for high volume production conformal coating of printed circuit board assemblies with temperature limited components.

FEATURES:

  • Fast Curing – typically ready to handle in just minutes
  • Solventless Formulation
  • Low Viscosity – may be used in many spray or flow coating applications
  • Excellent Adhesion – outstanding long-term moisture protection
  • Low Modulus/Low Stress – minimizes coating-induced CTE stress to sensitive components
  • Flame retardant: UL94V-0 recognized (File No, E135148)
