Momentive’s SILTRUST™ ECC3011 and ECC3051S silicone conformal coating materials employ a unique formulation that can prevent the occurrence of corrosion on vital PCB components and surfaces.

These coating materials have been shown to dispel the commonly held perception that silicones, due to their higher gas permeability, are at a disadvantage in the prevention of corrosion. In corrosion tests performed by Momentive in accordance with IEC standards, Momentive’s new silicone formulations outperformed a select group of conformal coating materials in including acrylics, polyurethane, polyolefin and competitor silicone formulations.

Momentive’s silicone conformal coating materials are currently available in two grades varying in levels of hardness and required cure time. Technical documents for these products are available in the table below.
