Predictive power for life and residual life of the zinc rich primer coatings with electrical measurement
Zinc rich primers with lamellar and spherical shaped zinc pigments and their combinations
were formulated. These zinc rich primers were used to measure the electrical conductance
and subjected to the corrosion analysis for 3000h. The lamellar shaped pigments at lower
PVC were found to be better than spherical shaped pigments, whereas the typical
combination of spherical and lamellar zinc was the best in providing corrosion protection. A
set of equations were developed to predict the life and residual life for pigment of both …
