Anti-corrosion Coatings
Guaranteed Long-term Corrosion Protection with IGP Powder Coatings.
Therefore, to retain its positive properties over time, steel requires an anti-corrosion primer and a weather resistant, practically impervious coating. IGP-KORROPRIMER powder coatings are the ideal two-coat systems for your steel constructions. They actively protect substrates such as steel or galvanized steel against all forms of corrosion and also enrich surfaces with an outstanding aesthetic appeal.
Corrosion Factors: Environmental and Man-made
Factors that cause corrosion include environmental conditions, such as high humidity or salt content in coastal atmospheres, as well as pollution and increasingly intensive UV radiation.
Residues from metal-machining processes can also accelerate corrosion. The most well-known example of corrosion is rust formation on iron. This is caused by the production of an oxide that is a solid substance. As the corrosion advances, it builds up on the metal surface in the form of a thick, porous coating. This reduces the positive properties of the steel such as its load-bearing capacity, strength, and toughness.
However, corrosion not only affects steel substrates. Filiform corrosion attacks coated aluminum substrates exposed to chlorides in combination with high humidity.
Corrosion Categories: the Right Protection at every Location
Tests in accordance with DIN 55633 and DIN ISO 12944-6 have confirmed the benefits of IGP’s eco-friendly, highly durable powder coating systems for corrosion protection.
To achieve optimal corrosion protection, choose the right coating structure for your substrate and application field. Professional application is vital to ensure that the powder coating system fulfils its optimal anti-corrosion function.
Simply call or write to us if you have any questions regarding product application. The IGP corrosion specialists will be happy to give you expert advice.
C3 – moderate:
Application fields: urban areas and industrial atmospheres with moderate sulfur dioxide pollution, food industry, breweries, laundries, mild coastal climate with low salt load
C4 – severe:
Application fields: industrial atmospheres, severely polluted urban regions, swimming baths, chemical plants, coastal areas with medium salt load
C5 – extreme:
Application fields: industrial atmospheres with high relative humidity and aggressive atmospheres as well as coastal and near-coastal areas with high salt load, extreme humidity, extremely corrosive atmospheres, industrial plants in subtropical and tropical climates
IGP-KORROPRIMER
The Ideal Powder Coatings for Galvanized and Cast Components.
IGP-KORROPRIMER powder coatings are the ideal two-coat systems for your steel constructions. They actively protect substrates such as steel or galvanized steel against all forms of corrosion and also enrich surfaces with an outstanding aesthetic appeal.
Porous metal substrates such as hot-dip galvanized steels tend to exhalate during the curing process. This is why blisters often form beneath the surface of conventional powder coatings.
Certificates: Tested Quality
Powder Coatings with High Corrosion Protection for all Application Fields.
The eco-friendly and extremely hardwearing IGP-KORROPRIMER systems for corrosion protection of steel are characterized by outstanding properties. Renowned institutes have certified them in accordance with the corrosion categories set out in DIN EN 12944-2. Furthermore, they meet the requirements of powder coating systems according to DIN 55633 for alloyed and non-alloyed steel as well as DIN EN ISO 1461 for hot-dip galvanized steel components in thicknesses of at least 3 mm. IGP regularly engages independent laboratories and institutes to test our corrosion protection systems. We also carry out extreme stress and endurance tests in our own labs. At your request, we would be happy to provide you with certificates for the IGP corrosion protection systems at any time.
IGP products are certified by these organizations:
Qualisteelcoat – The IGP powder coatings
IGP-KORROPRIMER 10 and IGP-KORROPRIMER 60 in combination with the top coats from the IGP-DURA®face 58 series are certified for application on blasted and galvanized steel structural components. Depending on the structure and substrate, the powder coating systems offer corrosion protection up to class C5-H.
Qualicoat International – certification body for the coating of aluminum for architectural applications
IGP-KORROSYSTEM 60: Qualicoat-certified two-coat system (No. P-1854) for aluminum substrates, consisting of IGP-KORROPRIMER 60 and any Qualicoat-tested IGP top coat (e.g. IGP-KORROPRIMER 6007A70xx0A00 and top coat 5903A90050S70).
SP – Technical Research Institute Sweden, Chemical and Material Technology
The Swedish institute tested and approved coatings with IGP-KORROPRIMER systems in accordance with STD VCS 1027.149 “Accelerated corrosion test”. This test is a high-level version of the salt spray test widely used in the automotive industry, for example.
IGP Certified Coater Program: Certified Expertise
Damage to substrates can only be avoided if the corrosion protection work is carried out professionally. Otherwise, corrosion can progress unnoticed under the surface and increasingly weaken the substrate.
Only qualified personnel with special expertise can ensure effective corrosion protection. The IGP Certified Coater Program guarantees expert application of corrosion protection systems for the prevention of damage. IGP technical consultants inspect coating partners and certify them in accordance with IGP standards.
The internationally recognized DIN label quality mark, plus confirmation by a renowned certification institute, give our customers the security they need. They can count on the top anti-corrosion properties of IGP primers and powder coatings.
IGP Corrosion Testing: our Service for your Security
The most important functions of corrosion protection systems from IGP are guaranteed surface quality and permanent corrosion prevention. Benefit from a special IGP service – using standardized testing equipment, IGP carries out corrosion testing on your specific coated structures.
You get the results of this corrosion testing in accordance with DIN 55633 or DIN EN ISO 12944 for your own records. You can also request tailored advice from IGP expert consultants. They will tell you all you need to know about the correct coating structure for corrosion protection of your substrates.
