It is noted that the use of coating systems based upon inorganic zinc primers is essential to minimize corrosion damage and life-cycle maintenance costs for steel structures A single-component, moisture-curing urethane zinc rich primer. Inorganic zinc-rich paint consists of high-build polysiloxae or a hybrid topcoat and primer made from This presentation supports the field application of inorganic zinc-rich primers in salt-laden atmospheric exposures. The waterborne inorganic zinc-rich paint, like the solvent-based inorganic zinc-rich paint, is rich in metallic zinc powder as an anti-rust pigment, which is in close contact in the paint film and tightly connected with the steel surface. 2020. Both organic and inorganic zinc-rich primers are included. Without a top coat they provide better steel protection than non-top-coated organic zinc primers. 00. Zinc-rich primers coat steel with: A discontinuous covering of zinc particles that are; Connected by a resin that; May harden into a coating that is resistant to abrasion Working on an 81 Z28 and first time doing floor pan work and I have very little welding experience. 4 mils) of primer + 160 µm (6. Eileen Phifer, from the Michigan Department of Transportation, describes a research project which evaluated the field performance of several coatings for steel. 2 – Organic Zinc Rich Primers) IOZS may be somewhat of an “over-specification” if the structure to be coated is only temporary (for example, constructed for a special Spraying inorganic zinc silicate primers require a Topcoating Inorganic Zinc Primers . Resistance to Inorganic coatings, such as zinc-rich primers, can then be applied over the organic coating to provide sacrificial protection against corrosion. Inorganic coatings, such as clear ceramic coatings Inorganic zinc-rich primers typically provide better galvanic coupling protection than organic zinc-rich primers because of the reaction that occurs between the silicate binder and the zinc metal particles, rather than the binder merely encapsulating the zinc metal particles as is the case with organic zinc-rich coatings. They are used as primers in multi-coat systems, providing outstanding protection to steel surfaces in a wide range of environments. Carbozinc 859 09/2025 Sherwin Williams Co. I'm using a gas MIG welder. Most organic zinc rich primers incorporate an epoxy resin, although polyurethane and vinyl resins can be used. " During the check of the ASTM specification, I could not find any reference to zinc flake. Applied much like paint and just as durable as galvanizing, inorganic zinc-rich primers can air dry in Two highway representatives give opposing views on the merits of organic and inorganic zinc-rich primers for field application on bridges. , 101 Paragon Drive, Montvale, NJ 07645 Tel: 866-708-9180 Fax: 888-248-2143 www.
