Abstract
A process for preparing an insulated product comprises forming an electrodeposited layer having high inorganic powder content by dipping a substrate in an electrodeposition varnish prepared by admixing an inorganic powder with a water dispersion varnish and electrodepositing the inorganic powder, and impregnating an organic or inorganic insulation varnish into the spaces of the electrodeposited layer.
Claims8
A process for preparing an insulative product which comprises:
- immersing a substrate in an electrodeposition varnish prepared by mixing an inorganic powder having a particle size smaller than 20 mesh with a water dispersion varnish;
- electrodepositing the inorganic powder from said electrodeposition varnish to form an electrodeposited layer of high inorganic powder content on said substrate;
- and immersing said varnished substrate in an organic or an inorganic insulation varnish to impregnate the spaces of the electrodeposited layer with said insulation varnish.
