Anticorrosive pigments containing lead have already been used for corrosion inhibition
for a long time.
The anticorrosion action of these pigments is based on certain amount of water soluble
chromate which migrate to the metal surface to initiate and sustain the formation of
passive layers. Which is the basis for anticorrosive effect of chromate containing
pigments.
The particle shape and size, particle size distribution and dispersibility of the pigment
have to be adjusted to achieve optimal corrosion inhibition.
Zinc Chromate, Strontium Chromate & Barium Chromate are most effective
anticorrosive for application in aircraft and coil coating primers.
The objective of the pigmentation in all cases is to prevent the contact of water, oxygen
and other corrosion supporting components. (Ions from salt, acids and hydroxides) with
the metal surface to be protected.
