Montmorillonite as corrosion protective pigment (original) (raw)

 MMTs are not inert; rather, they may act as smart pigments with complementary properties being activated as the coating is damped with corrosive medium.  Beyond barrier properties, montmorillonites (MMTs) may improve coatings performance by active corrosion inhibition.  Also, regulation of pH suggests smart anticorrosive action of hydrophylic MMTs for acid media.  Organophilization treatments of MMTs may have collateral effects on coatings performance.  Benefits may depend on testing conditions, MMT type and content.
