Abstract

See full text

Use of the barrier property effect of nanomaterials to improve the electrical insulation resistance and corrosion protection strength properties of electromagnetic devices. The beneficial effects are realized with nanomaterial loadings of 1-20%, and preferably between 1-5%, parts by weight of coating resins. Nanomaterials include, but are not limited to, silica, alumina, zirconia, and antimony pentoxide, which are dispersed either directly into a coating, or pre-dispersed in a carrier appropriate to the solvent of the resin system. The rheology of the resin system is not significantly altered which would otherwise affect processing of the resins for their intended applications.
