Impregnating resins and varnishes are a key component of modern motor, generator and transformer production. They turn the laminated core and the wire winding into a homogenous and mechanically stable unit. The advantages are excellent protection from a wide variety of environmental factors as well as improved heat transfer between wire winding, slot insulation and core.
Know-how derived from experience The development of impregnating materials is closely related to one name: DuPont™ Voltatex®. It is the result of a continuous exchange of know-how with all leading manufacturers in the electrical and electronics industry. As a result, manufacturing processes have been improved continually while products have been tailored to a wide variety of differing requirements. Today, impregnating resins from DuPont™ Voltatex® are available for all common processing techniques: dip & bake, trickle and encapsulation.
