Steel constructions of all kinds must be protected against corrosion in order to maintain static safety and fatigue strength.
The new and innovative powder coating system of ENVIRAL® Oberflächenveredelung GmbH is based on an intelligent and highly effective corrosion protection (SmartCorr®) as well as an excellent antifouling protection against the permanent formation of microorganisms and the adhesion of e.g. mussels.

The SmartCorr® product developed by ENVIRAL® Oberflächenveredelung GmbH is based on the basic research of the Max Planck Institute of Colloids and Interfaces in the field of nanotechnology. It is patented and exclusively licensed to ENVIRAL® by Max Planck Innovation GmbH.
On this basis, Prof. Dr.-Ing. Bernd Bachert is working on the further development of an innovative and sustainable powder coating system for hydraulic steel construction as part of an R&D project in cooperation with ENVIRAL®. Independent testing institutes such as the Federal Waterways Engineering and Research Institute (BAW) and the Institute for Antifouling and Biocorrosion Dr. Brill and Partner are also integrated.
The new powder coating system is free from bisphenols, VOCs (volatile organic compounds) and halogens. It does not contain PVC, phthalates or other plasticizers.
- excellent corrosion protection
- convincing antifouling properties
- longer service life
- less maintenance cycles and costs
- reduces downtimes and thus improves profitability
- responsible towards environment
- water-friendly and harmless to flora and fauna
A fatigue test simulating 35 years of fatigue strength stress showed very good results for the colour samples coated by ENVIRAL® with SmartCorr® and antifouling.
"The samples only show slight deformations at the fixing points, but these do not have a negative effect on the functional properties. In addition, the samples were tested for their insulating properties before and after the test using 'poro-Scan porosity detection' and found to be good," states Prof. Dr.-Ing. Bernd Bachert, who is highly satisfied with the results.
After almost four years of exposure in an extremely corrosive environment, the SmartCorr® coating shows excellent behaviour under real-life conditions. Corrosion attack is minimal even on artificially created damage. Classically coated comparison samples tend to be close to failure.
"The innovative SmartCorr® corrosion protection has already been successful proven in real life in recent years. We are all the more pleased to be able to use and further develop the high requirements as a basis for hydraulic steel construction," says Ing. Rainer Rogovits, Managing Director of ENVIRAL®.
