The NFHolzlack research project is dedicated to developing innovative coating systems for wood used outdoors. The aim is to significantly improve protection against weathering and mechanical stress by incorporating natural fibres into wood coatings.
Although existing wood coatings extend the service life of windows, doors and façades, they are susceptible to damage from hail, UV radiation or temperature and humidity fluctuations. Cracks in the varnish layers often lead to moisture penetration and consequential damage to the wood. This is where the project comes in. The fibres incorporated into the coating dissipate forces, bridge microcracks and increase the resistance of the paint. As a result, the coatings remain intact for longer, maintenance intervals are extended and maintenance becomes more economical and sustainable.
There is a particular focus on the use of plant fibres from agricultural residues. Instead of energy-intensive glass fibres, for example, renewable raw materials are used that were previously mostly unused or used for energy production. This opens up new value creation potential – especially for rural regions – while at the same time ruling out competition with food production.
With a combination of improved material performance and resource-saving raw material selection, the project makes an important contribution to climate protection, resource efficiency and a more sustainable construction industry. The research project will test in practice how natural fibre-reinforced coatings can be formulated, applied and tested for durability. The aim is to create a new generation of wood coatings that not only reduce the burden on the environment but also offer economic advantages for builders, craftsmen and industry.
The project, with the funding code 49MF240110, is funded by the Federal Ministry for Economic Affairs and Energy as part of the INNO-KOM module ‘Market-oriented research and development’ funding guideline.
