Copolymer varnish. II. Application test results

摘要

In 1997, a new copolymer technology, utilized in the formulation of a family of electrical varnishes, was introduced. Laboratory test results were utilized to illustrate the superior performance characteristics of the new technology. A comparison was made to typical polyester and epoxy varnishes through performance results in a series of benchmark tests. The purpose of this paper is to provide a technology update based on information garnered through two years of field testing in a variety of end use applications.
