NOT RECOMMENDED FOR: contact with potable water, strong acids or strong alkalis
WATER IMMERSION: 100°F (38° C)
SURFACE PREPARATION: Dependent upon surface conditions and intended service. Typical examples are as follows:
| Grease & Oils | Solvent to clean SSPC-SP1 |
| Rust Scale | Power tool clean to SSPC-SP3 or SSPC-SP11 (SIS St 2 or 3) |
| Mill Scale, Paint or Heavy Rust | Sandblast to SSPC-SP6 (commercial) (SIS Sa 2) |
| Water Immersion | (100°F (38°C) Maximum) Sandblast to SSPC-SP10(near white) (SIS Sa 2.5) |
APPLICATION METHODS
BRUSH/ROLLER/AEROSOL
Apply as received in 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 type)
| Atomized Air Pressure | 50 Lbs (1.3 kg/cm²) |
| Fluid Pressure | 15 to 20 Lbs (0.4-0.6 kg/cm²) |
| Orifice of Tip | 0.080 inches (0.20 cm) |
| Viscosity Reduction | 4:1 Mineral spirits -OR- 16:1 Xylene |
SPRAY (airless type)
| 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. |
| Recommended Procedure | Connect hose directly to pump ensuring a hose length of 50 ft. max. Use least pressure possible. Start at 1500 lbs. (680kg) and increase as required for good spraying. |
CLEAN UP: Mineral Spirits or Xylene
DRY TIME (set to touch): When ambient air dried, 20-30 minutes @ 1.5 mil (38µ) thickness
RECOAT TIME (2nd coat of ZRC): 12 hours.
TOPCOATING: After 24-48 hours, ZRC may be topcoated with acrylic, chlorinated rubber, epoxy, urethane or vinyl type products. DO NOT TOPCOAT WITH ALKYD, ALKYD-MODIFIED ACRYLIC, OR LACQUER TYPE PRODUCTS.
Where can you use ZRC?
Bridges
ZRC is used to protect steel structures, such as railings.
Construction
Unlimited uses: on structural channel frames, as part of curtain wall support systems or curtain wall mullions.
Fabrication
Long-term protection of miscellaneous metals.
Public Projects
ZRC is specified as the base coat for the protection of structural support steel.
Transmission Towers
Used as original protection for structural steel and for regalvanizing support cables. Also over worn hot-dip.
Industrial Maintenance
Used for maintenance of structures and equipment inside and outside industrial, petrochemical and food processing plants (Acceptable to USDA and FDA).
Manufacturing
Used by international manufacturers such as Leach Co., Oshkosh, WI to prevent corrosion on the inside surfaces of water tanks.
Instead of Hot-Dip
Makes galvanizing an “in-plant” operation for many manufacturers.
Nuclear Plants
ZRC has many applications in all phases of construction.
Off-Shore Rigs
Protects above and below the water line.
Water & Waste
ZRC is used to protect steel in extremely hostile environments such as water and waste plants.
Tanks
ZRC is used on the exterior surface of water tanks. For example, a tank was protected by ZRC in an extremely corrosive environment for over 20 years.
Parabolic Antennas
ZRC is used extensively as a base coat in a two-coat system for the superior protection required in highly corrosive locations.
