Electrical insulating varnish is applied by spraying, trickling, and brushing method. Based on method of application, the electrical insulating varnish market can be segmented into trickle impregnation method, Vacuum-Pressure impregnation (VPI) method, and dip and flood impregnation method. Based on type of varnishes, the electrical insulating varnish market can be divided into impregnating varnish and finishing varnishes. Trickle impregnation, dip and flood impregnation, and VPI methods are used to impregnate varnish. On the other hand, brushing and spraying methods are used to apply finishing varnishes. The major disadvantage related to the dip and flood impregnation method is that the coating is applied on unwanted parts of winding. The trickle impregnation method is advantageous, as it offers no drain loss, high retention & consistent quality. In terms of demand, the trickle impregnation method segment is anticipated to account for significant share of the market during the forecast period.
