Corrosion Prevention: What is Corrosion?

Experts have estimated the annual global cost of metallic corrosion to be $2.5 trillion. It is believed, however, that with proper corrosion prevention and protection techniques, this cost can be reduced by up to 30%. Corrosion can indirectly be costing to manufacturers by leading to weaker equipment and products, which can cause accidents, safety concerns, a damaged reputation and in some cases, serious payouts.

So, what exactly is corrosion?

Corrosion is the transformation that takes place when a refined metal reacts with oxygen or sulfates, oxidising to a weaker version of itself. The most common type of corrosion is rusting, where iron or steel reacts with oxygen and water, forming an orange-brown substance.

Corrosion is a common phenomenon across many industries, namely automotive, aerospace and marine.

What Causes Corrosion?

Corrosion is a process that takes place naturally. Factors that can accelerate the rate of corrosion range from:

  • Exposure to moisture in the air – high humidity
  • Extreme temperatures
  • Presence of salts – acidic water environment
  • Surface moisture
  • Exposure to electric currents
  • Exposure to dirt or bacteria
  • Build up of liquid in small gaps – causes crevice corrosion
  • Continous or changing tension in a corrosive environment – causes stress corrosion.

Car Underbody Protection

In the automotive industry, manufacturers must protect their vehicles from corrosion damage by rust-proofing the car underbody with a car underseal. Cars that are regularly driven on rough roads or in countries with varying weather conditions are especially prone to rusting on their underbody through contaminants, stone chipping and other damaging conditions. This can lead to damage to the car by allowing water and dirt to get through the underbody – a problem that can only be solved through a costly repair that either comes under warranty or leaves the owner with a large bill to pay.

Top Solutions for Corrosion Prevention

Common ways of preventing corrosion include choosing non-corrosive metals, such as stainless steel or aluminium, using a sacrificial anode, or ensuring a clean and dry metal surface.

Although, one of the most effective techniques to prevent corrosion, is using anti-corrosion coatings that are tailored to protecting vehicles to allow for longer, high-quality performance. Tectyl high-performance anti-corrosion sprays and coatings provide protection for this exact purpose. Anti-corrosion coatings protect materials by preventing contact between the material and harsh environments such as temperature and chemicals. Tectyl coatings are cost-effective and long-lasting solutions that can be applied to a wide range of applications, including pipes, roofs, exteriors, tanks, machinery and panels; providing a reliable solution to an array of automotive corrosion pain points.

Opting to use corrosion prevention coatings allows manufacturers to increase the reliability of their vehicles to reduce unexpected costs by limiting repair needs.

Tectyl 506

Tectyl 506 is a multi-purpose corrosion prevention compound that can be used in various applications. It provides excellent protection of metallic surfaces against corrosion in the automotive, bus & truck, marine, rail and aviation industries. It is wax-based and fast-drying. Various grades of Tectyl 506 exist, including Tectyl 506-WD (water displacement), Tectyl 506-EH (extra-heavy) and Tectyl 506-G (gelled).

Tectyl Amber

Tectyl Amber is a wax-based, water-displacing corrosion prevention compound that is ideal for use on door panels, side sills and frames. It is available as an aerosol and is effective even in small seams and crevices.

Tectyl 5750W Black

Tectyl 5750W Black is a water-based, non-volatile and quick-drying corrosion preventive compound designed to be used as a car underbody coating. It provides excellent abrasion resistance and protection against stone chipping and corrosion in trailers, railroad carriages, buses, truck cabins and cars.
