Silicone Conformal Coating

Conformal coating material is a thin polymeric film which conforms to the contours of a printed circuit board to protect the board’s components. Typically applied at 25-250 μm(micrometers) thickness, it is applied to electronic circuitry to protect against moisture, dust, chemicals, and temperature extremes.  Coatings can be applied in a number of ways, including brushing, spraying, dispensing and dip coating

We offer Momentive Conformal Coatings. Maintaining the appearance and functionality of a surface requires a coating that delivers protection from harsh weather, high temperatures and abrasive chemicals. Momentive’s specialty coatings portfolio offers this line of defense for an array of hardcoat, weatherstrip, anti-fog, release and electronic applications. Our coatings can provide excellent thermal, chemical, solvent and abrasion resistance, as well as improved adhesion to substrates for applications from automotive lighting, exterior trim and interior parts, to sensitive electronic components, tapes and

Momentive’s ECC3011 and ECC3051S silicone conformal coating materials employ a distinct formulation that helps 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 corrosion prevention. In corrosion tests performed by Momentive in accordance with IEC standards, Momentive’s new silicone formulations out-performed a select group of conformal coating materials,  including acrylics, polyurethane, polyolefin and competitor silicone formulations.
