Abstract: Ceramic heating devices with a three-dimensional ceramic element are disclosed for protecting surfaces from icing. The shape of the three-dimensional ceramic element can be configured to physically match to the three-dimensional profile of the protected surface, allowing for high thermal coupling with the surface. The shape of the three-dimensional ceramic element can also be configured to form an aerodynamic surface typically found on the exterior of aircraft.

Abstract: Heater assemblies and other electrical components are provided having protective coatings that allow for use in high temperature and highly corrosive environments. Methods for applying protective coatings are also provided. In one embodiment, a component is provided and includes a protective coating that encapsulates at least a portion thereof. The component can be, for example, a heating assembly that includes a heating element and at least one lead operably coupled to the heating element, or a component that is disposed within a dosing tank in a selective catalyst reduction system having an engine that is configured to emit an exhaust stream. Methods for coating components are also provided.

Abstract: Electrical component assemblies and other electrical connectors are provided having protective coatings that allow for use in high temperature and highly corrosive environments. Methods for applying protective coatings are also provided. In one embodiment, a connector is provided and includes a protective coating that encapsulates at least a portion thereof. The connector can be, for example, an electrical lead frame, or a connector having a distal side and a proximal side that is disposed in an automotive fuel system such that the distal side is sealed from the proximal side. Methods for coating connectors are also provided.

Abstract: A sensor assembly with a protective coating and a method of applying the coating is disclosed. The sensor assembly includes a sensor, a first conductive lead extending from the sensor, a second conductive lead extending from the sensor, and a protective coating encapsulating the sensor and portions of the first conductive lead and the second conductive lead proximate to the sensor, wherein the protective coating comprises a fluoroelastomeric polymer. The coating is applied by immersing the sensor assembly into a cooled fluoroelastomeric polymer and then withdrawing the sensor assembly.
