PROCESS FOR PROTECTING AN ELECTRONIC DEVICE WITH A HYDROPHOBIC COATING

摘要

Methods for protecting an electronic device from contaminants by applying multiple polymeric layers on the vital components of a device are disclosed. In one embodiment, the method comprises applying a multilayered, hydrophobic coating that is inert to electrical conductivity on one or more components of the device. The method includes applying to a component of a device a first layer comprising a first polymer, such as a silicone-based polymer, and a second layer comprising a second polymer, such as an acrylic-based polymer on top of the first layer. Each of the first and second layers exhibits a water contact angle greater than 90°, such as at least 110°. Electronic devices that are protected by such multilayered, hydrophobic coatings are also disclosed. Non-limiting examples of such devices include smart phones, computers, and gaming devices.
