The new corrosion protection coating, “SikaCor® SW-1000 RepaCor,” developed in a research association, promises a significantly simplified, faster, and more cost-effective on-site repair of wind turbines. Following the successful start in February 2018, a free product training course this year in Rostock provides an insight into the possible applications on wind turbines and technical information. The event will again be organized by WindSourcing.com GmbH together with Sika Deutschland GmbH on February 12, 2019 (German) and February 13, 2019 (English) in Rostock.
The four- to five-hour event is aimed at all service companies involved in the maintenance and repair of wind turbines. It consists of a theoretical part and practical exercises.
“The aim is for the participants to be able to reliably use the product themselves after the training and pass on the knowledge to their employees,” said Stefan Weber of WindSourcing.com, managing director of the Hamburg-based trading company. “Various practical applications in recent months have confirmed this: The product is a revolution in the repair of corrosion damage to onshore and offshore wind turbines.”
The use of wind power, especially on the open sea, demands the highest standards of corrosion protection — and thus maintenance — due to the mechanical and climatic conditions.
“A long and thus profitable service life of the turbines can only be achieved with conscientious maintenance,” Weber said. “The systems cannot simply be transported away, especially on the high seas. All work has to be carried out on site in wind and weather — often by industrial climbers who can only handle heavy tools and material to a limited extent.”
In addition, protective coatings have to dry and harden quickly due to the weather, Weber saod. This is exactly where SikaCor® SW-1000 RepaCor comes into play.
The solvent-free 2-component coating material is the result of the three-year research project RepaKorr, which sought — and found — solutions to the problems mentioned above. The Fraunhofer Institute for Manufacturing Technology and Applied Materials Research (IFAM), among others, was involved in the joint project funded by the Federal Ministry of Education and Research.
Between 2013 and 2016 Sika Deutschland GmbH was in charge of the material requirements and launched SikaCor SW-1000 RepaCor on the market in summer 2017.
“The coating dries four hours faster than conventional systems,” Weber said. “The practical packaging in the form of mixed cartridges facilitates processing and thus guarantees absolute process reliability with minimum waste at the same time. Industrial climbers are thus loaded with low weight.”
Other properties include single-layer performance (corrosion protection as with multi-layer systems), UV and colour stability and Norsok M501 approval with ISO 20340 testing.
On February 21, 2018, WindSourcing.com, together with Sika Deutschland GmbH, welcomed, for the first time, customers from the service sector for wind turbines in Hamburg to present the new corrosion protection SikaCor SW-1000 RepaCor in a product training course. Besides other participants, the team of Christian Schulte, managing director of Windspektrum GmbH, also took part in the training.
“The product training with WindSourcing.com and Sika appealed to my team and me very much,” he said. “The product ‘SikaCor® SW-1000 RepaCor’ was professionally presented. In addition, all participants were able to test the product extensively and direct their questions to the two trainers. The networking on the evening before the training was not neglected either.”
