In recent study, waste fly ash, a by-product from coal power stations was converted into zeolite NaY for its successful utilization as an anticorrosive pigment in paints.The synthesized zeolite NaY was modified by exchanging its nominal cation Na+1 with Mo+1 ion. The Mo+1 exchanged zeolite was used as an anticorrosive pigment in coatings. Coatings were formulated using various percentages of the synthesized pigment in epoxy resin. The coatings in epoxy resin were applied on mild steel substrate.The results indicate effective anti-corrosive properties of the fly ash based zeolitic pigments containing Mo+1.
