    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.
