A coating material having specific resistivity and secondary emission characteristics. The coating material described herein is especially well-adapted for coating a spacer structure of a flat panel display. In one embodiment, the coating material is characterized by: a sheet resistance, rho sc, and an area resistance, r, wherein rho sc and r are defined as: rho sc>100( rho sw) and r< rho sw(l2/8).In the present embodiment, rho sw is the sheet resistance of a spacer to which the coating material is adapted to be applied, and l is the height of the spacer to which the coating material is adapted to be applied. By having a coating material with such characteristics, the present invention eliminates the need to place rigorous secondary emission characteristic requirements on the material comprising the spacer structure in a flat panel display. More specifically, the present invention eliminates the need for the spacer material to meet rigorous secondary emission characteristic requirements in addition to meeting requirements such as, for example, high strength, precise resistivity, low TCR, precise CTE, accurate mechanical dimensions and the like.
