Anti-corrosion coatings create a chemical-physical barrier that protects the metal substrate from oxidation, chemical attack, and surface degradation, ensuring long-term durability even under extreme environmental conditions.
Thanks to tailored polymer formulations and high-adhesion applications, these coatings provide effective protection for steel, stainless steel, aluminum, light alloys, and non-ferrous metals. They ensure resistance to humidity, salt spray, industrial detergents, and severe environmental cycles.
They are widely used in industries such as mechanical engineering, energy, electronics, plant engineering, medical, transportation, and packaging, where stable and certified protection against corrosion is required, whether in continuous exposure or intermittent contact with atmospheric agents or technical fluids.
Main benefits and advantages of anti-corrosion coatings
Effective corrosion barrier
Protects metal components from humidity, salt spray, and acidic or alkaline agents, extending their service life
Food-contact compliant chemical protection
Polymer coatings specifically formulated for corrosive environments, ideal for components in contact with food and compliant with current food contact regulations
Stability in aggressive environments
Maintains performance under critical conditions: temperature changes, chemical exposure, and environmental stress
Combined chemical and mechanical resistance
In addition to corrosion protection, some coatings also provide abrasion resistance and withstand industrial cleaning processes
Suitable for various materials and geometries
Applicable to smooth, complex, or micro perforated surfaces, with both protective and aesthetic finishes available
Process reliability and compliance
All coating cycles are controlled and repeatable, compliant with industry regulations, and tested according to international standards

Frequently asked questions (FAQ): anti-corrosion coatings
What is the difference between epoxy, polyurea, and zinc coatings?
Epoxy coatings based on epoxy resins, often two-component systems that cure through chemical reaction. Typically applied by spray, roller, or brush.
Polyurea coatings obtained from the reaction between isocyanates and amines, applied via hot-spray at high pressure.
Zinc coatings (hot or cold galvanizing): a cathodic protection process that coats steel with a zinc layer. This can be performed by hot-dip immersion or by cold-applied painting systems.
How long does an anti-corrosion coating last in industrial environments?
The actual service life of a coating depends on the chemical environment, exposure conditions, and abrasive factors it is subjected to.
In industrial practice, accelerated tests are available that simulate real working conditions and help predict long-term performance.
Are they safe for food-contact environments?
Depending on their chemical composition, some coatings are suitable for and can be certified for food-contact applications.
Is it possible to repair or touch up a damaged coating?
In some cases, depending on the type of coating and the nature of the required repair, small touch-ups or local repairs can be performed.
