Abstract:
An epoxy resin composition is disclosed for joining dissimilar materials. The identified epoxy resin compositions can be used to seal metallic and non-metallic components of a capacitor. Specifically the epoxy resin composition can be applied to joints between a non-metallic capacitor bushing and a metallic tank cover and metallic terminal cap. Once the epoxy resin composition is cured, it can provide a seal that can withstand the stresses and environmental conditions to which a capacitor is subjected.

Abstract:
Thin film ceramic foil capacitors are produced using inline reel-to-reel processing techniques by starting (100) with a length of copper foil which serves as one plate of the capacitor, then depositing (120) a layer of a ceramic precursor on a portion of one side of the copper foil at a first station. The foil is advanced (117, 127, 137, 147) to the next station where the ceramic precursor and the copper foil are heated (130) to remove any carrier solvents or vehicles, then pyrolyzed (140) to remove any residual organic materials. It is then sintered (150) at high temperatures to convert the ceramic to polycrystalline ceramic. A final top metal layer is then deposited (160) on the polycrystalline ceramic to form the other plate of the capacitor
