Corrosion protection and resistance to weathering

Besides being decorative and functional, the most important requirement of a coating is to protect surfaces. The high diversity of materials, ranging from metals, mineral materials through to plastics and composites, means that coatings have to fulfil very different and very high demands. As well as being adapted to the material and requirement concerned, it also has to be possible to apply these coatings using industrial processes that are both cost-effective and environmentally friendly.

We help companies develop and assess coating systems fulfilling the necessary requirements. We carry out publicly-funded as well as contract research projects for our customers in the following key areas:

  • Corrosion protection coatings for steel and galvanized steel in the steel industry
  • Tests on polymer dispersions for water-dilutable, one-component corrosion protection systems
  • Tests on corrosion protection pigments and fillers for corrosion protection coatings
  • Surface pre-treatment and corrosion protection in the automobile and vehicle industry
  • Multi-metal substrates and corrosion protection in the automotive industry
  • New pre-treatment methods as alternatives to treatment with zinc phosphate
  • Surface pre-treatment and coatings to protect aluminium materials against corrosion
  • Development of short-time tests for corrosion-protective coatings
  • Corrosion protection testing techniques, such as conventional methods, new VDA and electrochemical testing methods
  • Barrier properties of coatings, transportation of water by coatings
  • Artificial weathering of coatings
  • Photocatalysis on pigments and coatings
  • Chemical resistance of coatings
