Epoxy zinc-rich primer: The zinc content is usually between 65% and 85%. Epoxy zinc-rich primer has excellent adhesion and chemical resistance, and is suitable for metal protection in industrial and marine environments.
For steel structures that are exposed to high temperatures or for a long time outdoors: Choose inorganic zinc rich primer, which provides better weather resistance and high temperature resistance. For locations requiring high adhesion and chemical resistance: Choose organic zinc rich primer.
