The protection of metals from corrosion has been a major concern in Australia. Thanks in large part to the proximity of the ocean, metal is quite vulnerable to rusting. This requires effective coating systems to protect the metal and rust remover to get rid of the existing corrosion.
For outdoor constructions made from metal, providing proper corrosion protection and removal of existing rust can be a time-consuming effort. However, if you choose the right approach, you can maximize the protection of metal and effectively deal with the formation of rust in the early stages. All this with less effort, especially when using the correct products.
Liquid Corrosion Inhibitors
Most coatings provide some protection to the metal underneath. But using a liquid corrosion inhibitor helps prevent the formation of rust to a far greater degree. Such inhibitors can be found in paint or in clear coating products. This means you can improve the resistance of the metal to corrosion, lower the cost of rust removal, and protect the environment at the same time.
However, before you race off to the nearest store, it helps to understand exactly how it all works.
Why Metals Corrode in Australia
In truth, some metals in Australia are not subject to corrosion. But iron-based metals which constitute most of the building materials made of metal can corrode quickly when unprotected. The corrosion itself is caused when the iron-based metal meets with oxygen. This produces a reaction that causes the rust to form.
Because the conductivity of the oxygen is greater in sea water compared to fresh water, the rust forms even faster. This leads to weakening the metal, damaging parts that are adjacent, and altering the surface as it is covered in rust. The rust is not just a change of appearance, but a change in the metal itself.
Corrosion Protection Coating Systems
The corrosive reaction may be augmented by contaminants on the surface of the metal. Depends on how well the coating layer that provides protection comes into contact with the surface, and the overall quality of the corrosion protection itself.
How to Reduce Corrosion Effectively
Adding a corrosion inhibitor is essentially providing a layer between the metal and the outside air or water. This prevent the corrosion from occurring as long as the layer is strong, durable, and prevents all contact that otherwise would start the corrosive process.
A conversion coating is often used in paints designed to inhibit the formation of rust. Zinc or iron phosphates are normally part of the coating that cling to the surface of the metal once it has been immersed in the solution.
This process applies a thin film, such as a primer or paint to the surface. A four-step process, it also offers a barrier to prevent corrosion from occurring.
There are other corrosion protection coating systems as well. They provide solid protection that can prevent the metal from forming rust. If you see rust on the surface, a rust remover is recommended. Plus, the sooner it can be applied, the better it will work. For those living along the coast of Australia, having the right combination of rust prevention and removal will help protect metal structures for a long time.
