Increase your knowledge in bio-based coatings for construction

To reduce its environmental impact the construction industry is continuously looking for alternative solutions. One of them is the use of bio-based coatings and paints. The improvement and replacement of components of paints and coatings formulations is a challenging process, because of a possible impact on the final properties of the coating. A new project aims to establish and validate novel bio-based coating systems for use in the construction industry, by replacing fossil ingredients with bio-based ones with the same or better performance and durability.

The construction industry must limit its major environmental impact. Worldwide, construction is responsible for about 50% of carbon emissions, 20–50% of consumption of natural resources, and 50% of total solid waste. Therefore, construction companies look for alternative materials that have less negative impact on the environment. One of these alternatives is the use of bio-based coatings and paints. The construction industry is by far the biggest user of paints and lacquers and responsible for at least 50% of the total consumption.

Most of current coatings used are still based on fossil materials. Switching to to bio-based materials would have a positive impact on the climate, environment and the image of the construction industry. However, the improvement and replacement of any components of paints and coatings formulations is a complex, challenging process, because small changes to the chemistry of one component nearly always entails a re-formulation of the entire coating and have a possible impact on the final properties of the coating. That means that every company, who wants to develop or use the new developed products has to test, adapt and optimise.

The main objective of the European CORNET-project BIOCoCo is to establish and validate novel, bio-based coating systems for use in the construction industry by replacing fossil ingredients with biobased ones with equal performance and durability or even surpass the performance of fossil-based coatings.

Combined expertise

Within BIOCOCO, research institutes Sirris in Flanders, Materia Nova in Wallonia and Fraunhofer in Germany combine their expertise in bio-based resins, fillers and functional additives to develop new bio-based coatings for the construction industry: 

  • Sirris will screen, modify and evaluate solvent and water-based epoxy systems from which the most promising will serve as a basis for addition of biobased additives developed by the research partners.
  • Materia Nova will develop in-can preservatives with lower toxicity and compliance to regulation, allowing anti-moss activities, based on biotechnology development
  • Fraunhofer IFAM will develop vegetable-based capsules for self-healing corrosion protection coatings.
  • Fraunhofer IPA will develop multifunctional fillers such as keratin and chitosan for UV and bacterial protection

The knowledge gathered is a basis for industrial companies for development of new bio-based coating formulations with high sustainability for application in construction.

Participate to this project!

Interested in accelerating your knowledge building? We are looking for cooperating companies from Belgium and Germany to become member of the steering committee. Joining the steering committee will give you the opportunity to integrate your challenges into the research and present use cases for which the new developments can be demonstrated. The project will give you first-hand insight in the results obtained and networking opportunities with companies from the value chain.

In order to make the steering group as relevant as possible, we are looking from companies, especially SMEs, in the full value chain including, companies developing bio-based materials for coatings, paint manufacturers, paint applicators and end users in the construction industry.

If you are interested in this research, don’t hesitate to fill in the following document and give some information why this research would be of interest for you. As we believe this research is important for our companies, we offer free membership to the guidance group for Flemish companies expressing their interest before 17 September 2021.
