    The Proof Is In The Paint


    Our unique formula provides a self-healing galvanic film that is impossible for others to match. The ZRC difference is made possible by ZRC’s high zinc content (95% by weight in the dried film) of “ultra-pure” zinc dust (ASTM D520 Type III) and proprietary, non-encapsulating binder. Here’s why ZRC and GALVILITE are superior.

    Frequently Asked Questions

    What is ZRC?

    ZRC is the brand of the highest quality zinc-rich coatings on the market containing 95% "ultra-pure" zinc dust by weight in the dried film. They bond to clean iron, steel, or aluminum to provide maximum protection against rust and rust creepage through "galvanic action". The ZRC product lines consist of ZRC®, GALVILITE®, ZRC®221, and ZERO VOC ZRC. ZRC Worldwide has been registered to the International Organization for Standardization ISO 9001 Series Standards for Quality.


    What are the major uses for ZRC's zinc-rich coatings?

    ZRC is widely used to prevent rust and rust creepage in place of hot-dip galvanizing, as well as the following major uses:


    • High-performance base coat for a variety of topcoats

    • Repair of damaged hot-dip galvanizing, Galvalume®, and zinc metalizing

    • Regalvanizing worn hot-dip galvanizing, Galvalume®, and zinc metalizing

    • Repair of weldments on galvanized material

    • Repair of damaged inorganic zinc coatings.


    How does ZRC work?
    "Ultra pure" Zinc dust is integrated with our trade secret organic binder. This binder allows the zinc particles to remain in contact with each other so that the ZRC is anodic to the base metal, thereby imparting true galvanic action.

    Is ZRC a paint?
    No. Although ZRC is commonly applied like a paint (brush, roller, aerosol, compressor type or airless sprayer) it is unlike any type of paint because it provides galvanic action and will not allow any rust creepage. Please refer to our "Guide to spray application of ZRC" if you plan to spray ZRC. Paint (any sort of paint) gives only skin-type protection. If this skin is broken, it not only rusts at the break but also allows rust to creep under the film.

    Is ZRC equivalent to hot-dip galvanizing?
    Yes. Based upon the Underwriters' Laboratories, Inc. original (Dated 9/3/58) and continuing yearly re-examination Component Testing Program (#58c2975), ZRC is recognized as an equivalent to hot-dip galvanizing. To our knowledge, ZRC is the only cold galvanizing compound to be considered a recognized component under the Component Program of U.L., Inc.

    Other FAQs

    Where can I buy ZRC?

    ZRC products are non-hazardous for ground transportation, so they can be shipped by UPS as well as a common carrier, factory direct or through our worldwide network of authorized distributors. No minimum order requirements for factory direct shipments paid by MasterCard, Visa, American Express, COD or Prepaid orders and strive to ship within 48 hours of receipt of order. Call our Customer Service Department 1-800-831-3275 or send an email request for your nearest ZRC distributor. Because it works! It is the only cold galvanizing compound on the market that is ISO 9001 registered, U.L. approved and recognized as an equivalent to hot-dip galvanizing. Its low VOC levels are accepted in all 50 states and it is non-hazardous for ground transportation. If you are considering a different brand, check the technical data, specifically the salt-fog corrosion tests, to determine how it compares to ZRC. We think that when it comes to protecting your metals, it makes sense to use the very best.

     

    In most coating jobs, labor is the most expensive element. So, use your labor wisely by applying the maximum protection possible - ZRC and GALVILITE cold galvanizing compound.

    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

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

    Doug McLean | President, McLean's Blacksmithing, Inc., Galveston TX

    The main advantage of ZRC was that it allowed us to provide galvanized protection on site without delays to the project. Another important factor in specifying ZRC is its true cathodic action. With the volume of heavy traffic passing through the transit shed doors, it is likely they will be scratched. ZRC should provide zinc protection even when the doors are scratched to bare metal.
