Water-resistant coating for computer digital data storage device

Abstract

A low cost method of applying a water-resistant coating to the exterior of a computer digital data storage device is provided. The storage device is compatible with industry standard 2.5 inch or 3.5 inch drive sizes and is either dipped into a reservoir of liquid elastomeric, rubberized epoxy compound or by applying a thermoset polyurethane polymer to the exterior surface of the storage device by reaction injection molding. Both methods produce a coating which has high thermal conductivity and high electrical resistance so that the storage device will operate properly. The resultant form of the water resistant coated digital data storage device is compatible with industry standard 2.5 inch and 3.5 inch computer hard drive bays. Both methods lend themselves to high speed automatic application, thereby greatly reducing the applied cost of the coating. The invention also pertains to the coatings, themselves, as applied to the exterior surfaces of a computer digital data storage device compatible with industry standard 2.5 inch and 3.5 inch computer hard drive bays.
