Abstract
A multi-level sealing method wherein an electrical element to be sealed is heated. Once heated, a quick curing first seal is applied to the electrical element thereby preventing the introduction of moisture, and other elements, into an electrical element as the seal cures. A second seal is applied, over the first seal and the element, that is high temperature and slow curing. As a result, the second seal has a different grain structure and the likelihood of a common moisture path into the electrical element is substantially eliminated. Therefore, once the high temperature, slow curing, second seal has cured, the reintroduction of moisture into the electrical element is prohibited. Additional layers of sealant may be added, if desired.
