Overview
The present invention relates to a novel modified zeolitic extender pigment from industrial waste that can be used in anticorrosive paints. Fly ash, an industrial waste from thermal power stations has been modified by alkali fusion followed by hydrothermal treatment to obtain a nanosized mesoporous material. Metal ions specific for corrosion protection were incorporated in its structure. The modified fly ash based material when used in paints as an extender, exhibited significant anticorrosive properties.
