ABSTRACT:
A method includes: immersing a semiconductive substrate in an electrodeposition composition, wherein at least 20 percent by weight of resin solids in the composition is a highly cross-linked microgel component, and applying a voltage between the substrate and the composition to form a dielectric coating on the substrate. A composition for use in electrodeposition includes a resin blend, a coalescing solvent, a catalyst, water, and a highly cross-linked migrogel, wherein at least 20 percent by weight of resin solids in the composition is the highly cross-linked microgel. Another composition for use in electrodeposition includes a surfactant blend, a low ion polyol, phenoxypropanol, a catalyst, water, a flexibilizer, and a highly cross-linked migrogel, wherein at least 20 percent by weight of resin solids in the composition is the highly cross-linked microgel.
