The effectiveness of corrosion protection provided by paints and coatings cannot be fully evaluated solely through acceptance inspections of the finished coating. Factors such as environmental conditions and application methods also play a crucial role. However, many coated products and structures do meet the requirements for extended service life. Such coatings often successfully provide long-term protection against corrosion as specified by their design and performance requirement.
This seminar offers newest insights into overcoming the challenges of achieving long-term durability for coated surfaces. It will cover both fundamental principles and mechanisms, as well as real-world industrial case studies and ways of monitoring coating performance i.e., water uptake and adhesion as well as real time monitoring of coated structures under atmospheric conditions. Additionally, the seminar will address the opportunities and limitations of current testing methods and standards.
Participants will have excellent opportunities for networking and sharing experiences across various industrial sectors and academic disciplines, with the goal of developing solutions, technologies, and tools to enhance corrosion protection.
The program will continuously be updated.

How to specify the right coating system for your project? Claus Weinell, Senior Consultant, DTU Chemical Engineering Selecting the right coating system for your project is key to obtaining the longest service life of your asset. There is no “one-size-fits-all”. The coating system should be selected with careful considerations to several factors. E.g. the environment the coating system should serve in, the expected durability of the system, the possibility of maintenance and repair, anticipated extended service life, any special stress on the coating system during service, and many other things. |

Atmospheric paint systems for offshore wind structures – experiences and risk areas Anders Rosborg Black, Senior Corrosion Engineer, Ørsted Wind Power Protective coating systems in the atmospheric zone offshore requires the right specification, surface preparation, application and quality control. If executed correctly very long lifetimes of the overall system can be expected. However, corrosion issues are still experienced in “risk areas”, e.g. areas with field repairs, around welded attachments, bolted joints, and other assembly connections. |

Insights in coating performance through impedance measurements Vadimas Verdingovas, Senior Scientist, Hempel Electrochemical impedance spectroscopy (EIS) is a standard method for evaluation of coatings performance. Typically, these are single time measurements conducted either at different stages of coating testing, or during sampling campaigns / inspections in the field. This presentation introduces two new setups enabling continuous monitoring of coatings performance through impedance measurements. The first setup utilizes embedded sensors and has been developed for testing of coatings under harsh cyclic conditions such as typical for corrosion under insulation (CUI). The second setup utilizes a dedicated sensor board, the use of which allow real time monitoring of coating curing/drying, and characterization of water uptake. Vadimas Verdingovas is a Senior Scientist at the Technology Centers, R&D Denmark at Hempel A/S. His current focus is on development of new setups and test methodologies based electrochemical methods and sensors with the aim of improving development and testing of new coatings and materials. |

The significance of Coating inspection Nana Eckhardt, Specialist, FORCE Technology Steel structures are exposed to aggressive environment, that will cause premature break down by corrosion if not sufficiently protected. Coating as paint or galvanization are widely used as protection, but they are not efficient unless correctly applied. FORCE Technology performs independently consultation and third-party inspection regarding corrosion protective coatings. In this contribution, we will present why thorough preparation and inspection is of great significance, when and how it is performed and give examples of what kind of flaws we are typically finding and correcting during our inspections. I have been employed as Specialist at FORCE Technology’s Materials Consultancy department since 2009. I am mainly working with corrosion protection issues, and the tasks spread over all phases of the structure’s lifetime from the design phase where the corrosion protection is specified, over production inspection, hand-over inspections to repair and renovation specification and supervision. Typical are also cases where the client and supplier or other parties disagree over the quality of the corrosion protective coating delivered |

The wetting and adhesion of epoxy coatings to contaminated substrates - a comparison between solvent- and waterborne coatings Qiong Li, Post Doc, DTU Chemical Engineering The presentation will focus on understanding why waterborne and solvent-borne epoxy coatings exhibit inadequate surface tolerance when applied to non-ideal surfaces contaminated with engine oil, silicone oil, and flash rust. The wettability mechanisms are uncovered by analyzing the interactions between the surface tension of liquids and the surface free energy of solid surfaces using the Owens, Wendt, Rabel, and Kaelble (OWRK) approach, as well as the acid-base theory. The mechanistic insights gained from this work can contribute to enhancing the wettability and adhesion performance of organic coatings, particularly on substrates contaminated with oil and rust. Qiong Li is a Postdoc at the Hempel Foundation Coatings Science and Technology Centre (CoaST) within DTU Chemical Engineering. She completed her PhD on Curing Induced Internal Stress in Epoxy Coatings at CoaST in 2022. Currently, her research focuses on uncovering the fundamental mechanisms responsible for the reduced wettability and adhesion performance of waterborne and solvent-borne epoxy coatings when applied to non-ideal surfaces contaminated with oil stains and flash rust. |
