Corrosion protection
Functional corrosion protection is particularly important for coating systems that are used in an aggressive climate - for example, offshore in the energy industry, in coastal regions or in hydraulic engineering. Here, many high-performance coating systems are now available, some of which also allow high protection durations on an aqueous basis.
Lars Baumgürtel: How we can save our industry
Die mittelständische Industrie steht vor großen Herausforderungen: Hohe Energiekosten, übermäßige Bürokratie, marode Infrastruktur und ein akuter Fachkräftemangel beeinträchtigen die Wettbewerbsfähigkeit. Lars Baumgürtel, geschäftsführender Gesellschafter der ZINQ Gruppe, spricht über notwendige wirtschaftspolitische Weichenstellungen, stabile Energieversorgung, wettbewerbsfähige Kreislaufwirtschaft – und wie wir unsere Industrie mit Innovationen zukunftsfähig machen müssen.
Decorative problem caused by waterlogging
Corrosion damage is not always due to errors in pre-treatment or coating. Sometimes constructive peculiarities coincide with particularly unfavourable environmental conditions.
DFO: Fehler durch falsches Strahlen
In the current defect of the month, DFO is investigating damage that originated in the blasting process. Severe blistering had occurred on a component coated with powder coating.
DFO: Too much of a good thing
Time and again, coating problems such as adhesion problems or insufficient corrosion resistance are caused by inadequate pre-treatment. In this case, excessive concentrations of substances in a silane-based pre-treatment process led to adhesion problems.
DFO: What zinc coatings don't like
Lack of adhesion of galvanised coatings not only affects organic coatings, but often the underlying inorganic coatings, as shown by three different cases in which DFO Service GmbH determined the cause.
Atotech: More sustainable and better
Nearly 80 participants came to the Corrosion Protection Summit in Frankfurt. Here there was news about coating systems, testing standards and exciting guest lectures directly from the industry, from the screw manufacturer Nedschroef to Porsche.
DFO: Edge covering in corrosion protection
When discussing the performance of anti-corrosion coatings, the word edge coverage is often mentioned. The term refers to the ability of the coating material to achieve a sufficiently high film thickness in relatively sharp-edged areas of the object to be painted.
30 percent lighter
Tests have shown that improved corrosion protection with zinc flakes makes it possible to reduce the material thicknesses of chassis parts without compromising safety.
Protecting CFRP and GFRP effectively
Composite components are often exposed to harsh environmental influences. The right coating protects them effectively and helps them last longer. A leading paint manufacturer offers solutions for coating modern composite materials.
No splitting hairs
The series of standards of DIN EN ISO 12944 and DIN 55633 contain requirements for corrosion protection by coating systems on unalloyed and low-alloyed steel. However, the standards differ in essential points that should be considered before tendering and ordering.
Durable protection and chromium(VI)-free decorative coatings
High corrosion protection, improved depth scattering, optimised friction behaviour - a leading specialty chemicals manufacturer is presenting new solutions at the fair. Of particular interest are the improved processes for corrosion protection and TriChrom decorative coatings.
Stellantis is using Zinkflake-Technology: Protected on good and bad roads
Increasingly longer service lives with simultaneous weight savings - especially in the area of long-term corrosion protection, classic coating processes can only partially meet the requirements in the chassis area. Zinc flake technology is a promising alternative here.
More corrosion resistance and less seizure tendency
A special process for surface hardening of stainless steel makes it possible to improve the seizure and corrosion resistance of stainless steel. This is shown by the results of long-term corrosion tests on fittings, for example.
Corrosion and fire protection for Hamburg's public transport system
The steel structures at Hamburg's new "Elbbrücken" stop and transfer point for underground and suburban railway passengers are protected against corrosion and fire in the long term with coating systems.
Refurbishment instead of new acquisition
Steel components near the sea must be highly resistant to damaging environmental influences. Humidity, salty air and evaporation of chemicals cause accelerated corrosion. A coating system against such aggressive conditions can significantly extend the service life of components.
Nano coating for zinc die castings
A manufacturer of zinc die-cast parts uses a novel nano-coating to coat components for the automotive industry. Tests show that this also offers a very good protective effect in terms of abrasion and corrosion compared to galvanic coatings.
Rio anti-corrosion protection
A new process for metal pre-treatment is now being used successfully in Hanghzou, China. With the Betenio process, Rio GmbH has developed a genuine innovation in surface technology to series production readiness.
Interpretation involves risks
Standards sometimes offer some room for interpretation. If the client and contractor do not recognise and clear up these ambiguities, there is a lot of potential for problems.
