ABSTRACT:
An electrically insulating wire coating material comprised of the heat cured product of a mixture of polyvinylacetal and phenol-aldehyde resins, or a mixture of these resins with epoxy resins, and a catalyst from the special metal containing group of cyclic organic compounds known as chelates and which can be further defined as being a non-ionic inner complex salt. These materials give insulating coatings with improved flexibility and thermal aging properties.
