A formulation comprising, by weight, 4.7-39.7 percent polymethylmethacrylate (PMMA), 0-9.1 percent plasticizer and 60.3-93.0 percent dielectric glass (along with an appropriate amount of solvent) is ball milled to an appropriate size for spraying. After the formulation is sprayed onto a substrate, it is baked at a temperature of approximately 620 DEG C. for approximately 2 hours. During the baking step, the PMMA decomposes to a methylmethacrylate monomer. The resultant dielectric coating will contain a small amount of residue (less than 1 percent) of the monomer and the plasticizer.
