Ask the Expert Question-and-Answer Archive by Ron Joseph June, 2010Zinc Chromate Primer and Red Oxide Zinc Chromate Primer Q. Is there any difference between zinc chromate primer and red oxide zinc chromate primer? Please clarify. A. Zinc chromate is a chemical that is added to a primer to prevent or retard corrosion. Red oxide is also chemical that provides excellent exterior durability. A red oxide, zinc chromate primer contains both chemicals; one to prevent or retard corrosion, and the other to provide excellent exterior durability. You get the best of both worlds.
