Abstract
A sol composition for producing dielectric layers on a metallic substrate including 10 to 30%, by weight of the sol composition, of a precursor including a trialkoxysilane, 10 to 40%, by weight of the sol composition, of titanium dioxide particles whose median size is below 500 nm, 4.5 to 36%, by weight of the sol composition, of silica particles whose particle size distribution D90 is below 100 nm, 5 to 15%, by weight of the sol composition, of a solvent capable of making the precursor miscible in water, 0.1 to 2%, by weight of the sol composition, of an acidic catalyst, the remainder being water.
