Rail freight transportation is a system service where a multitude of players, participants and systems providers bear a high degree of responsibility for its attractiveness and performance. It shows high efficiency as transportation means, in terms of land use and energy consumption and low greenhouse gas emissions. However rails market share of freight transportation and its economic efficiency continues to be limited. Aimed at overcoming such uncertainty, this project addresses one of the most important key resources for further developing rail freight transportation: the optimization of the performance of the rail freight wagon. The continuous pressure on environmental issues and energy efficient transport is forcing the rail transportation sector to enhance the rail logistics services and to incorporate innovative solutions to improve load capacity to keep the best-in-class position and, therefore, acquiring a much privileged position beyond alternative terrestrial transport source, as truck transportation. Thus, aimed at optimizing rail freight transportation, the main objective of this project is to holistically address the aspects that may improve freight wagon performance: enhanced logistics, improved multimodal operative, higher load capacity, optimized filling/emptying time and flexibility to transport multi-products. This project aims to achieve such optimization by combining industrial expertise on the freight wagon design and construction, advanced materials for lightweight construction and logistics with the research capabilities to incorporate innovation solutions and optimize material performance.


The present invention relates to a method for the establishment of a crack resistant epoxy paint coat and paint compositions suitable for said method. The method is developed for use in ballast tanks e.g. a ballast tank of a vessel. The method involves the steps: (i) applying a paint composition comprising an epoxy-based binder system onto the surface thereby forming a curable paint film on the surface, and (ii) allowing the curable paint film to cure thereby forming the epoxy paint coat. The paint composition has a viscosity of at the most 140 KU, when ready to be applied. The paint composition comprises 35-80% by solids volume of the paint of an epoxy-based binder system having a ratio between the hydrogen equivalents and the epoxy equivalents in the range of 20:100 to 120:100. The paint composition furthermore comprises 0.5-30% by solids volume of the paint of one or more fibres. The fibres have an average length, of at the most 250 m.


The present application discloses a fouling release cured paint coat comprising a polysiloxane-based binder matrix constituting at least 40 % by dry weight of the coat, 0.01-20 % by dry weight of one or more non-reactive fluorinated oils, and 0.1-10 % by dry weight of one or more biocides. The application further discloses a marine structure comprising on at least a part of the outer surface thereof an outermost coating prepared from the specified coating composition, and the combination of one or more fluorinated oils and one or more biocides for improving the antifouling properties of a polysiloxane based coating composition.


The application discloses a method for applying a fouling-release coating system to a surface, said surface suitably provided with an anticorrosive coat, and an article comprising a substrate, said substrate having a surface, preferably an anticorrosive coat on at least a part of the surface of said substrate and a tie-coat on said substrate. A curing agent composition comprising an amino-silane adduct comprising a high molecular weight amine, HMWA, as well as a tie-coat comprising said curing agent composition are also provided.
