Patent ID: 7964236

Claim:
A process for producing a storage stable liquid coating composition for an electromagnetic device to improve the electrical insulation resistance and corrosion protection properties of the device the process comprising: formulating a coating resin using a liquid, thermosetting resin material; forming a suspension of a nanomaterial in the liquid resin material by: (1) adding to the resin material between approximately 1-20% part by weight of an inorganic material having a particle size of between 1 and 150 nanometers; and (2) mechanically dispersing the inorganic material in the liquid resin material by mixing the liquid resin material and the inorganic material together to obtain a homogeneous liquid coating mixture; the liquid coating mixture being free of anti-settling agents; and storing the liquid coating composition in a liquid state and as a substantially homogeneous suspension until the liquid coating composition is applied to a substrate to form a coating on the substrate.
