ECC3051S is a one-component, low viscosity silicone conformal coating material that cures on exposure to atmospheric moisture to form a flexible protective coating. ECC3051S conformal coating cures quickly in ambient conditions without the need for curing equipment, and can achieve faster tack-free time with exposure to mild heat. ECC3051S conformal coating can help reduce the potential for corrosion of electronic components, and under certain test conditions* has been found to surpass other polymers such as acrylics, polyurethane, polyolefin and other silicone polymers in corrosion prevention.
FEATURES:
- Fast tack-free time
- Low volatility
- Solvent-free formulation (100% solid content)
- Contains UV indicator for ease in inspection under black light
- Continuous operating temperature range of -40 ~ 150 °C
- Flame retardant: UL94V-0 certified (File No. E135148)
- Meets IEC60068-2-52 Severity 5 standard for Salt Spray performance
- Meets IEC60068-2-60 Method 4 standard for Mixed Gas Corrosion performance
- Meets IPC-CC-830B / MIL-I-46058C standard for Appearance, Fluorescence, Thickness, Flexibility, Dielectric Withstanding Voltage, Moisture and Insulation
