Dialylphtalate impregnating resins

Dialylphtalate impregnating resins are one-component impregnating resins based on unsaturated polyester resin diluted in dialylphtalate. They are designated for impregnation of highly mechanical and temperature stressed electrical rotors and transformers of thermal class H (180 °C) by discontinuous technology of dipping, flooding by atmospheric pressure or by vacuum and pressure and by trickling. Dialylphtalate impregnated windings are cured by temperatures 135 – 150 °C in winding. Inconsiderable quantities of emissions are released by curing time. They do not pollute working environment and do not cause fire danger. Exhaust air does not have to be cleaned. Impregnated windings provide extraordinary high mechanical resistance; they are resistant to solvent vapors, freons, transformers oils and radioactivity.

It is designated for trickling impregnation of mechanically and thermally stressed windings of alternators and electrical rotating machines for domestic appliances and hand tools of thermal class H (180°C).
They are designated for impregnation of mechanically and thermally stressed windings of electrical rotating machines and transformers of thermal class H (180°C) by discontinue dipping or flooding technology under atmospheric pressure or under vacuum and pressure. Impregnating resin NH 91 is delivered according to TP VUKI - 0174/93, impregnating resin NH 91 LV according to TP VUKI - 0207/97.
