Extended service-life and improved properties of wood products through the use of functional nanoparticles in clear coating and adhesive systems

Objective

The long term objective of the WOODLIFE project is to provide coated and glued wood products with substantially improved durability for a more sustainable society. The project aims to develop new water-based clear coating systems for wood with improved UV-absorbing properties, and to develop new water-based thermoplastic wood adhesives with improved mechanical properties. The new coating and adhesive systems will be designed through molecular manufacturing of inorganic nanoparticles, nanoclays and composite organic-inorganic binders with predictable and controllable properties. Wood is an excellent building material with a high strength/density ratio and it is a renewable resource. For outdoor use it is, however, necessary to enhance the durability of wood materials due to the high sensitivity for UV degradation. Traditionally, organic UV-absorbers are used in clear coatings for wood, however these substances degrade upon outdoor weathering. New UV-absorbing systems for clear coats will be developed in the project based on nanoparticles of CeO2, ZnO and TiO2. With these new systems the service-life of the coated wood will be extended and the cost for maintenance and wood replacement will be decreased. If the mechanical properties of water-based thermoplastic wood adhesives such as PVAc can be improved it would be possible to use the wood products based on these systems for a longer time, leading to a more sustainable society. It would also be possible to use PVAc adhesives instead of the more expensive MUF/PRF adhesives in some load-bearing applications. Engineered nanoparticles will be developed in the project and will be introduced into wood adhesives in order to improve the properties of wood-adhesive joints. The nanoparticles and nanoclays that will be developed in the project will either be added directly to water-based systems or incorporated in hybrid binders in order to improve the dispersion of the nanoparticles and to improve storage stability.
