Elantas Zhuhai manufactured Epoxylite 478 Thixo is a low viscosity resin supplied as a single part impregnant for use with uncatalysed tapes. Similar in composition to Epoxylite 477, except it is slightly higher in viscosity and has thixotropic properties that provide greater retention on loosely wound structures and an improved surface build on enameled wire wound coils and taped apparatus.
Specifically designed as a V.P.I. impregnant for use on all types of electrical apparatus, taped coil, and enameled wire wound systems. With the proper processing cycle, it can be used throughout the low voltage range up to 7kV.
Applications of Epoxylite 478
Impregnation of medium voltage motors and generators
Random wound motors
Processing of Epoxylite 478
Please note: DO NOT PLACE units heated over 54°C into the resin. Heating the resin over this threshold will significantly shorten the shelf life of the material.
