2 days ago · A metal primer is a product that you usually spray or paint on metal to help prevent rusting and corrosion and at the same time creating a good surface for paint to stick to. The primer is made of chemicals and acids that go deep within the rusty metal and bonds with the rust to prevent the rust happening on the main piece of metal. What is the Process for Coating Metal with Zinc Jun 25, 2014 · The process for coating metal like iron or steel with a thin zinc layer is known as galvanization. The zinc layer serves to protect the metal from rusting. There are three different processes that can be used for galvanization. The two less-common processes are electrodeposition and electrochemical, while the one used the most often is hot dip galvanization. The basic idea

Aug 14, 2010 · I need to paint some Simpson hold downs that will be exposed on a deck I'm building. They are zinc plated. I went to a very good paint store, Dunn Edwards here in Los Angeles, and they offer two metal primers. One is a rust inhibitor primer, curiously water based. The other is for galvanized metal and I believe that is oil based. I'm not sure which would be the best choice. Introduction to structural steel primer selection SSPCZinc primers intentionally create a dissimilar metal relationship that provides cathodic protection to the steel. Because zinc corrodes preferentially to steel, zinc powder is added to primers. The corrosion of that zinc protects the steel beneath it. Its the same principal as attaching sacrificial anodes to ship hulls or other marine structures. Organic zinc primers use conventional binders like epoxies,
