## 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.
[ Use Cases ](https://www.zrcworldwide.com/products/zrc-zero-voc-galvanizing-compound#uses) [ Application Formats ](https://www.zrcworldwide.com/products/zrc-zero-voc-galvanizing-compound#applications) [ Product Specs ](https://www.zrcworldwide.com/products/zrc-zero-voc-galvanizing-compound#specs) [ Product Documentation ](https://www.zrcworldwide.com/products/zrc-zero-voc-galvanizing-compound#docs)
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.
Inorganic Zinc Coatings Repair ZRC is also effective for inorganic zinc coatings repair.
Galvalume® and Zinc Metallizing ZRC 221 can be used for Galvalume® and zinc metalizing projects.
#### Flexible Application Formats
Unlike hot-dip galvanizing, ZRC Zero-VOC Galvanizing Compound is portable, flexible protection that can be applied in a variety of formats.
Brush and Roller
### Brush and Roller
Follow mixing instructions. For brush application, we recommend only 100% Natural Chinese Bristle brushes. For roller application, we recommend rollers with a 3/8” nap, made of mohair or lambs wool (sheepskin).
Spray (Low Pressure Compressor)
### Spray (Low Pressure Compressor)
ZRC can also be applied as a spray. Notes:
- Typical Equipment Specification:
- Binks #95 siphon-fed conventional air gun
- Aircap: 66SK Fluid Tip: 66 SS
- Atomized Air Pressure: 40 psi (1.1 Kg/cm²)
- Fluid Pressure: 15 to 20 psi (0.4-0.6 Kg/cm²)
- Orifice of Tip: 0.080 inches (0.20 cm)
- Viscosity Reduction: Add water only if absolutely necessary
Spray (Airless)
### Spray (Airless)
Recommended Procedure: Connect hose directly to pump ensuring a hose length of 50 ft. max. Use in-pot agitator or continuous recycling. Use the least pressure possible. Start at 1500 lbs. (105 Kg/cm3) and increase as required for good spraying. Notes:
- Pump: 30:1 Ratio
- Hose: 1/2" (1.3 cm)(I.D.) Airless Type
- Orifice of Tip 60° - .026 in. (0.07 cm)
- Type of Tip: Tungsten carbide, reversing
- Filter Screens: Complete removal is recommended. However, if screens are employed, use no less than 30 mesh.
- Viscosity: No reduction required.

## 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.
Doug McLean | President, McLean's Blacksmithing, Inc., Galveston TX
##### Go With The Experts
Imitation is flattering, but the proof is in the paint. ZRC Worldwide created zinc coating technology to combat corrosion and has been a worldwide leader in the space for 70 years.
