How can I protect electronic goods from moisture and sea air damage?

Dr.sunil V June 5, 2014

How to safeguard electronic items against moisture and sea air? For example , a music player is exposed to sea air and moisture in rainy season. It is said that sea air contains salt and can quickly damage exposed electronic items. In the past , few electronic items have got spoilt with direct exposure to sea air and wind.

    Conformal coating helps, but does nothing for the exterior of the device. When I built units for use in dangerous environments, I used Pelican cases, and put cable gland passthroughs into the sides for power or other connectors. Waterproof and vapour proof. You can get Pelican cases as small as a wallet or as big as a steamer trunk.

      Thanks. Please tell , does pelican refer to nature of material used?

      Pelican is a brand name. There are others that are built in a similar manner, but I've found Pelican to be the best.

    Yes, conformal coating should do the trick.

      Thanks. I viewed the link and observed that it protects circuitry boards. So it can be sprayed after opening the gadget or externally without opening the gadget?

      Conformal coating material is applied to electronic circuitry to act as protection against moisture,

      Please tell , can simple plastic covers be used to protect sea air and moisture accessing device interiors ( say , music player's interior through the player's openings or columns communicating to exterior )? If yes , are such custom plastic covers available on online shops which can generally fit music player?
