Unituff Coatings: Tips on Keeping Rust Away from Metal Parts and Equipment
Rust is the orange-brown flakes of iron oxide that form on the surface of any metal-containing iron and has been exposed to water, air, or chemicals. Rust is a type of corrosion that is both unsightly and highly destructive.
The process of rusting usually starts when iron reacts with oxygen as water, saltwater, acids, or harsh chemicals are present. As iron oxide flakes off the metal surface, it exposes new iron molecules, and the rusting process continues unabated. Eventually, large areas of rust will form and will cause the whole metal structure to disintegrate.
Only iron can rust, but ferrous metals contain iron as well. Common ferrous metals include alloy steel, carbon steel, and stainless steel. Aluminium and copper are examples of non-ferrous metals and contain very little iron, if any, and will only corrode, but will not rust.
Regular Maintenance: Keep it dry and clean
Rust can spread quickly, so it is vital to scrape it off as soon as it appears. Either the whole metal or the portion of scraped- off rust can be scrubbed with warm water and applied with a protective coating to prevent further oxidation. A new coat of paint can also be applied when necessary. Remember that water is the main enemy of metals. Metal exposed outdoors to the elements is more likely to rust, or if the metal is stored in a humid indoor environment, such as the basement or warehouse. Keep metals clean as mud or dirt adhering to the surface can also hold water.
Cracks and scratches in metal might hold water, making it come in direct contact with iron. A protective coating can prevent rust from forming after the metal has been repaired or the scratch covered up.
Use Galvanised or Stainless Steel
Galvanised steel keeps steel rust-free for many years. When steel is galvanised, the steel is coated with liquid zinc. This zinc coating acts as a barrier preventing oxygen and water from reaching the steel. With stainless steel, though it contains some iron, it also includes a high percentage of chromium. The chromium in the alloy oxidises quickly to form a protective layer of chromium oxide on the metal that prevents water and oxygen from reaching the metal.
A Protective Coating
To provide strong corrosion resistance for metals, a protective coating such as polyvinyl chloride copolymer can be applied. Commercially available rust prevention products such as Unituff 452 can be applied to protect all kinds of metal objects, tools, outdoor metals, and large metal parts.
