Anticorrosion Protection

Kortec and Anticorrosive Protection

Kortec specify an extremely wide range of all types of anticorrosive coatings, from cost-effective zinc phosphate and zinc-rich primers in the Ferroteq range, through Libert's moisture-cured inhibitive primers to specialist barrier coatings from the German brand Brantho-Korrux.

The team are expert in analysing the potential corrosive attack for each project and selecting the optimum system to ensure protection in the most efficient manner.

What is Corrosion?

Corrosion is the deterioration of a metal as a result of chemical reactions between the metal and its environment. Rust is the most common example of corrosion, but the oxidisation of iron is just one example of corrosion. The type of metal and the environmental conditions (particularly gases in contact with the metal) combine to decide the form and speed of deterioration.

The World Corrosion Organisation has estimated the annual global cost of corrosion to be approximately US$ 2.2 trillion, and that up to 25% of this could be avoided by the application of clear and uncomplicated prevention procedures. Utilising existing corrosion control technology could save US$ 660 billion worldwide.

Types of Anticorrosion Coating

There are three main methods of anticorrosion protection by coating. They all have advantages and disadvantages that also vary according to circumstance, so typically an efficient coating system will combine two or more types of protection to achieve the lifespan required in the specific environment of the product to be coated. Please see below for a text and video overview of each type of protection.

Barrier

The coating forms a non-porous layer that prevents the surrounding environment from accessing the metal. If these are used without any other coating and the film is damaged by impact or chemical attack, the substrate is then unprotected. Solid content and film thickness significantly affect the lifespan of the protection.

Inhibitive

Porous coatings that contain chemicals which react with the metal and with humidity as it penetrates the film, to form a passive layer on the steel surface. This reaction becomes less effective over time, due to this inhibitors are commonly used in primers that will be overcoated

Cathodic/Sacrificial

There are additives (commonly zinc) in the coating that react with the metal, and form a sacrificial anode that corrodes instead of the metal. This is effective even if the film is damaged, although the level of protection is dependent on the additive content level and the type of paint binder used.
