    At a Glance: ZRC Zero-VOC Galvanizing Compound

    ZRC ZERO VOC solves the problems inherent in traditional inorganic zinc coatings like: near-white sandblasting, difficult spraying, and short pot life. We’ve resolved these issues by creating a unique hybrid featuring the best features of organic and traditional inorganic zinc coatings. ZRC ZERO VOC offers the same true cathodic protection as our original ZRC, without volatile organic content, solvents, or solvent fumes.

    Recommended Uses
    ZRC is widely used without topcoats in place of hot-dip galvanizing and is deployed as a high-performance base coat with a variety of topcoats. Used for:
    Hot-Dip Galvanizing Repair & Regalvanizing A more accessible option for repair of worn hot-dip galvanized materials.
    Weldments Repair Our original compound can be used to repair weldments.
    Long-Term Protection It’s proven to be effective long-term protection for: structural steel, water and waste facilities, power plants, transmission towers and antennae, steel decking and bridges, and numerous OEM uses.

    Quotes from Our Customers

    It’s no secret we’re the industry-leading solution that lasts. Here’s what our
    customers have to say.

    Because of my experience in the field with this product, I always recommend ZRC in corrosive applications. I've used ZRC to regalvanize radar towers and catwalk gratings for the Navy at the base in Winter Harbor, Maine. I also used it on metal roofs and on salt water cookers at a canning company. In all cases, it has provided five years or more of rust-free protection.

    Roy Love | President, Loves Painting

    DAI needed a coating that was equivalent to hot-dip galvanizing since many major components are too big to fit in the galvanizing tanks," "ZRC provides the equivalent corrosion protection of ASTM A 123 galvanizing and is applied directly over sandblasted A 36 steel prior to top coating with chlorinated rubber or epoxy.

    Sandy Boog-Scott | Director of Materials, DAI

    Of all the painting systems I have used to protect ironwork in the past ten years, ZRC top coated with epoxy works the best — even in highly corrosive, humid environments.
