Wisconsin Zinc Coatings
Galvanic Protection for Illinois Steel Manufacturers
Zinc-rich primers provide long lasting galvanic protection to steel surfaces, protecting your steel or aluminum tanks, equipment and structural members from rust and failure. Symet, Inc.'s Wisconsin industrial coating and painting specializes in the application of zinc coatings to your metal castings, fabrications, weldments, pumps, pipe sections and structural components.
Zinc rich paints possess similar characteristics to a hot-dip galvanized zinc coating. With a high percentage of zinc in the dry film (i.e., after cure), these paints can synergistically combine with the corrosion inhibitive properties of metallic zinc. The zinc dust in paint is integrated with binders. These binders allow the zinc particles to remain in contact with each other so the zinc paint can provide cathodic protection.
Organic or inorganic zinc-rich paints usually are applied to a dry film thickness of 2.5 to 3.5 mils (64-90 µm). Organic zinc paints consist of epoxies, chlorinated hydrocarbons and other polymers. Inorganic zinc paints are based largely on ethyl alkyl silicates. The zinc dust must be at a concentration high enough to provide for electrical continuity in the dry film.
Symet, Inc.’s intensive Illinois abrasive blasting process prepares steel for direct contact with zinc coatings, ensuring perfect galvanic protection.
