SI-COAT 579 CM Corrosion Maintenance Coating for Long Term Steel Protection
South Africa’s climate is as diverse as its terrain — from the salty coastal air of Durban to the dry heat of the Karoo and the unpredictable storms of Gauteng. These conditions can be brutal on infrastructure, especially metal surfaces exposed to the elements. That’s where SI-COAT 579 CM comes in — a high-performance corrosion maintenance protective coating designed to withstand the toughest environments. It offers exceptional durability, reducing maintenance costs and extending the life of steel structures in harsh environments.
Built for South African Weather
Whether you’re dealing with coastal corrosion or inland UV damage, SI-COAT 579 CM offers reliable protection. Its silicone-based formulation creates a flexible, breathable barrier that resists:
- Salt spray and humidity (ideal for coastal regions)
- Extreme temperature fluctuations
- UV degradation
- Rain, wind, and dust exposure
This isn’t just a coating — it’s a long-term solution for preserving infrastructure, reducing maintenance costs, and extending the life of your assets.
Corrosion Protection for Mining: SI-COAT 579 CM
SI-COAT 579CN is trusted across the worlds mining operations for its exceptional durability and chemical resistance. Designed to perform in the harshest environments, this silicone-based coating offers long-term protection against corrosion, even in areas exposed to aggressive chemicals and acidic conditions common in copper mining.
Its primerless application and resistance to acid make it ideal for steel structures, equipment, and infrastructure in processing plants and open-pit operations. Whether you’re dealing with sulphuric acid exposure or abrasive dust, SI-COAT 579 CM delivers reliable performance where traditional coatings fail.
Easy Application, Long-Term Results
SI-COAT 579 CM is engineered for ease of use:
- Single-component system — no mixing required
- Fast drying and low VOC
- Can be applied to a variety of surfaces including steel, aluminum, and previously coated substrates
It’s ideal for use on bridges, pipelines, towers, and industrial structures — especially in regions where maintenance access is limited and durability is essential.

Hi,
I’m currently searching for an alternative to hot dipped galvanizing for our prop range, ideally the props to be dipped to coat internal and external surfaces including adjustment nuts and threads, it must also be resistant to the wear on the threads and adjustment nut, would SI-COAT 579 CM suit this application?
Good Day Gavin,
Thank you for reaching out to us, Silicone dipping is absolutely a viable option for props, and it brings several meaningful advantages. The coating offers strong chemical resistance, excellent hydrophobic properties and a consistent, attractive finish when applied by dip. Because it’s a high-solids formulation, it releases cleanly from threads, doesn’t become gummy and doesn’t interfere with adjustment mechanisms. Another practical benefit is that if the coating is damaged through normal handling, it can be touched up or repaired easily on-site without needing to redo the entire prop.
It’s important to note that silicone works as a barrier coating and doesn’t provide the sacrificial protection associated with zinc. That said, it performs very well in environments where chemical resistance, surface cleanability and easy maintenance are key priorities. Many clients use it either as a standalone barrier in moderate-wear conditions or as an added top layer over existing zinc systems to enhance overall performance.
A practical next step is an on-site test. Applying the coating to a small batch of props under real working conditions provides clear, direct feedback on performance. It also gives us the opportunity to visit, assess the environment and ensure the coating is matched correctly to their application. This approach keeps everything evidence-based and gives you the client confidence in the outcome.
Please let us know if a onsite meeting at your establishment is possible to discuss further.
