Patent number: 4081427Abstract: This invention relates to a process of reformulating a solvent polyester-type resin, such as employed in electrical insulation, for example in wire enamels, to a solventless polyester-type wire resin of similar properties which is characterized by increasing the relative hydroxy-functionality of said polyester-type resin as compared to the hydroxy-functionality of a corresponding solvent-type wire resin.In the preferred embodiment the increased hydroxy-functionality, in whole or in part, is derived from the use of, or the increased content, of tris(2-hydroxyethyl) isocyanurate. The polyester-type wire enamels include polyesters and polyesters containing other groups such as polyester-amides, polyester-imides, polyester-amide-imides, etc. By doing this, resins having the desired properties as well as viscosities suitable for wire insulation can be made and applied in solventless systems.Type: GrantFiled: December 20, 1974Date of Patent: March 28, 1978Assignee: The P.
