All You Need to Know about Corrosion Protection Products

Rust Prevention

Corrosion is the primary chemical reaction between any type of metal and its environment or elements from that environment. When corrosion occurs, the metal begins to oxidise. Metal oxidation or corrosion comes in different types. However, the most severe type is atmospheric corrosion. For instance, the combination of rain followed by the sun’s heat can be the onset of rust, thereby corrosion.

So, what are the different types of corrosion protection methods?

Active Corrosion Protection

The objective of this type of protection is to influence the reactions which proceed during corrosion. It is to control not only the corrosive agents but also the response itself in a way that can prevent corrosion. Examples using this protection method is the development of corrosion-resistant alloys or the addition of inhibitors to metals.

Passive Corrosion Protection

For passive corrosion protection, rust is prevented by mechanically isolating the metals from the aggressive corrosive agents, for instance, by using protective layers, membrane films, or other coatings. This type of rust prevention method will neither change the general structure or ability of the metals to corrode nor the aggressiveness of the corrosive agent. This is what makes this method passive. So long as the protective layer or film is intact, corrosion will never penetrate the metals.

Permanent Corrosion Protection

This protection method is mainly to provide protection at the place of use. It is preventing the stresses from climatic, biotic, and chemical factors from reaching the metals. For instance, heavy equipment or machines are located in factory sheds that offer protection from the weather and other extreme temperature variations that may be the cause of condensation. The factory sheds may also have additional external protection such as tin plating, galvanisation, coating, enamelling, and copper plating.

Temporary Corrosion Protection

Stress factors will always occur, such as sudden weather changes, extreme variations in temperature, and high salt content from sea salt aerosols. This can happen during land and maritime transport. A protective coating method or passive corrosion protection is typically utilised in these situations.   

Corrosion protection products can provide proper protection for all types of metal, either to prevent the onset of corrosion or to get rid of corrosion altogether. Rust prevention or corrosion problems can be solved with the proper use of corrosion or rust protection products. There is a wide variety of products for corrosion protection needs, but so far, one product that stands out is a polyvinyl chloride copolymer solution coating and external application called Unituff 452 (previously Seal’n'Peel).
