Variation in coating hardness during the EN 927-6 weathering test: influence of pigmentation
2016 - IRG/WP 16-40739
The objective of the SERVOWOOD project is to develop and establish European Standards that will facilitate the prediction of service life for exterior wood coatings. Within this project an extensive round robin exercise has been carried out by five partners to establish the repeatability and reproducibility of the EN 927-6 artificial weathering test. This round robin included the exposure of the I...

Development of methodologies to evaluate tanning blocking coatings
2016 - IRG/WP 16-40760
In Europe an increased interest in using home-grown hardwoods as sustainable and renewable construction materials started a few years ago. Amongst these species oak and chestnut are two interesting candidates as their heartwood contain a significant amount of tannins which contribute to their natural durability. To avoid wood greying and dimensional variations, oak and chestnut must be protected b...

Fungal growth on coated wood exposed outdoors: influence of coating pigmentation, cardinal direction and inclination of wood surfaces
2017 - IRG/WP 17-10896
The objective of the SERVOWOOD project was to develop and establish European Standards that will facilitate the prediction of service life for exterior wood coatings. One of the objective of this project was to study fungal growth of the field exposed panels. Two coatings applied in 2 and 3 coats were exposed for one year outdoors at 45° south: one solventborne (alkyd based) and one waterborne (a...

Functional silicones used for wood protection: preliminary study
2017 - IRG/WP 17-30720
Due to worldwide regulation the wood preservation domain is constantly changing. Silicones are used for different industrial applications as hydrophobic agents. This property could enable to reduce water uptake of wood treated with these compounds. Treated wood could then be less prone to dimensional variation and fungal attack, those parameters being driven by variations in wood’s moisture cont...

UV-curable coatings developed for aesthetic and biological protection of wood outdoors
2017 - IRG/WP 17-40821
To avoid wood greying, dimensional variations, and degradation by biological agents wood is protected with preservation products and coatings when used outdoors. For some wood species used for cladding, a treatment with a preservation product is required, and is frequently additionally protected with a coating. In this study, Mäder Group developed a new UV-curable coating for outdoors application...
