Momentive ECC3011 is a one-component, low viscosity silicone conformal coating material that cures on exposure to atmospheric moisture to form a flexible elastomer protective coating. ECC3011 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. ECC3011 conformal coating can help reduce the potential for corrosion of electronic components, and under certain tests, conditions have been found to surpass other polymers such as acrylics, polyurethane, polyolefin and other silicone polymers in corrosion prevention.
FEATURES AND TYPICAL BENEFITS:
- Fast tack-free time
- Solvent-free formulation (100% solid content)
- Contains UV indicator for ease in an 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
