Epoxy primer equals zinc chromate in corrosion resistance, revolutionizing coating industry.
The study compared the corrosion resistance of zinc chromate primer and epoxy primer on aluminum panels. They found that both one coat of epoxy primer and one coat of epoxy primer over zinc chromate primer showed equal resistance to salt spray corrosion. This means that using only epoxy primer can provide sufficient protection against corrosion, even without the zinc chromate primer.
