Suitable Substrates
Apply ZRC to properly prepared:
- Carbon steel
- Cast iron
- Hot-dip galvanized surfaces
- Aluminum
Proper surface preparation is essential for achieving reliable adhesion and coating performance.
95% Metallic Zinc Protection
The dried ZRC coating contains approximately 95% metallic zinc. As a result, it provides galvanic corrosion protection to suitable metal surfaces.
Furthermore, ZRC can be used without a topcoat in appropriate applications or as a high-performance base coat beneath compatible coating systems.
Temperature Resistance
ZRC offers excellent temperature resistance in non-immersion applications:
| Condition | Maximum Temperature |
|---|---|
| Continuous | 350°F / 177°C |
| Non-Continuous | 750°F / 399°C |
Therefore, it is suitable for many industrial environments where coated components experience elevated temperatures.
