ZRC® 221 - Lowest VOC for LEED /Green Projects, Battleship Gray Flat Finish, Gallon
The newest innovation in zinc-rich technology, ZRC® Low VOC Cold Galvanizing Compound offers the same superior performance with 40% lower levels of volatile organic compounds — a more environmentally friendly protection option.
ZRC® Low VOC Cold Galvanizing Compound
As the lowest VOC zinc-rich compound available, ZRC Low VOC Cold Galvanizing Compound offers the same protection as the original ZRC® Cold Galvanizing Compound with 40% fewer volatile organic compounds.
Recommended Uses
With it’s unique formulation, ZRC Low VOC Cold Galvanizing Compound is excellent for use in VOC-restricted areas. ZRC- Low VOC may be used without topcoat in place of hot-dip galvanizing. Also used as a high-performance base coat with a variety of topcoats. It’s specially formulated for:
- Hot-Dip Galvanizing Repair & Regalvanizing - It’s a more accessible option for repair of worn hot-dip galvanized materials.
- Weldments Repair - Our original compound can be used to repair weldments.
- Inorganic Zinc Coatings Repair - ZRC is also effective for inorganic zinc coatings repair.
- 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.
- Galvalume® and Zinc Metallizing - ZRC 221 can be used for Galvalume® and zinc metalizing projects.

Flexible Application Formats
Unlike hot-dip galvanizing, ZRC Low VOC is portable, flexible protection that can be applied in a variety of formats:
- Brush, Roller and Aerosol - Apply as received in the container. 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). ZRC can also be applied as a spray. Notes:
- Atomized Air Pressure: 50 psi (1.3 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: 5:1 ZRC-221 : parachloro-triflouromethyl-benzene (vol)
- Spray (Airless) - Recommended Procedure: Connect hose directly to pump ensuring a hose length of 50 ft. max. Use least pressure possible. Start at 1500 lbs. (680 kg) and increase as required for good spraying.
- 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
