Discussion of new developments in solventless polyestervarnishes-methods to meet EPA regulations and improve quality

摘要

An extensive study to determine the factors affecting buildup,flexibility, and mechanical properties of the base resins of solventlesselectrical varnishes is reported. The base resin formulation and monomerselection were found to have a significant effect on all properties. Asa result of this study, a new solventless varnish has been developedthat incorporates the high build and flexible characteristics ofconventional solvent-type varnishes with the high flash point, low VOC(volatile organic compound), and high bond strength of conventionalsolventless varnishes
