GALVAGRID® RUST ANODE PRIMER™ Galvanic anticorrosion protection SYNERDIS
GALVAGRID® RUST ANODE PRIMER™ Galvanic anticorrosion protection SYNERDIS
GALVAGRID® Rust-Anode Primer™ is a galvanic anti-corrosion solution designed for protecting hot-dip galvanized steel structures, especially in high-voltage electrical substations and saline environments. Developed initially with NATO, it offers active cathodic protection by fusing with steel to enhance its longevity.
Specifications
The primer is a single-component galvanic coating with 88% zinc content in the dry film and a zinc purity of 99.995%. It is applied at room temperature and offers a matte gray finish. The product is designed to be used with or without a final paint layer.
Application Scenarios
- Recharge on Old Structures: For structures with depleted zinc layers, GALVAGRID® can recharge the existing galvanization.
- DUPLEX™ System: For new structures in high corrosion classes, it doubles the lifespan of the anti-corrosion system.
Technical Characteristics
- Drying and Curing: Varies with temperature and humidity, with complete curing in 10-15 days.
- Performance: Offers high resistance to rust, blistering, and immersion in saltwater. It is compliant with various ASTM standards for adhesion, abrasion, and impact resistance.
- Temperature Range: Effective from -62°C to +120°C.
Advantages
- Provides active and sacrificial protection similar to hot-dip galvanization.
- Fast drying and high flexibility, suitable for high-voltage towers.
- Can be overcoated with most paints and powder coatings.
- Tested for toxicity under fire conditions.
Conclusion
GALVAGRID® Rust-Anode Primer™ offers a robust solution for extending the life of galvanized steel structures, providing superior protection against corrosion even in challenging environments.

GALVAGRID® Rust-Anode Primer™: GALVANIC ANTI-CORROSION PROTECTION Galvanize at room temperature– 50 years of use in industry and military. GALVAGRID® | TANK™ | PYLONE™ | SUBSTATION™ | INFRASTRUCTURE™ | OFFSHORE™ In high-voltage electrical substations, many components are made of "hot-dip galvanized" steel, which has been dipped in a molten zinc bath to protect against corrosion. HV gantries, electrical towers and pylons, retention tanks, fire protection covers, gratings, transformers, etc. are very often hot-dip galvanized. However, as they age, this zinc layer thins out and leads to rust formation,...
