VOC-free remedial treatment agent on organic solvent basis with surface cleaning by photocatalysis using titanium dioxide
2014 - IRG/WP 14-40651
Due to the EU Regulations according to the harmonisation of the European market of biocidal products and the EU Regulations regarding emissions of volatile organic compounds in residential properties a new VOC free yet organic solvent based remedial treatment agent is introduced including a potential method to clean up the wooden surface of remaining biocides after a remedial treatment using photo...

Decay resistance of wood treated with bio-friendly preservative systems
2016 - IRG/WP 16-30698
Due to more restrictive toxicological requirements and increased ecological awareness of consumers, wood preservatives containing biocides are no longer desired on the market. Therefore, research on new environmentally friendly formulations is of great importance. One of the possible solutions is to develop new preservatives based on natural substances, which are harmless to humans, animals and th...

The influence of log soaking temperature and thermal modification on the properties of birch veneers
2016 - IRG/WP 16-40749
In veneer manufacture the logs are routinely soaked in heated water baths in order to soften the wood prior to peeling. The temperature of the water may vary greatly between batches; however, the influence of log soaking temperature on veneer properties has had little research attention. Uncontrolled moisture is known to cause problems in wood-based materials, while thermal modification offers a m...

Bio-friendly wood protection systems - resistance to mould and blue-stain fungi
2017 - IRG/WP 17-30713
With stricter restrictions on the use of biocides and increasing environmental awareness there is a pronounced need for effective bio-friendly protection systems in the wood preservative and wood coating industry. One of the possible pathways is to exploit and utilize natural substances with active biological effects. Silanes, caffeine, natural oils and potassium carbonate were chosen as compounds...

Properties and potential use of Irvingia gabonensis and Irvingia wombolu kernel extracts as natural wood adhesives: Towards formaldehyde free wood composite products
2018 - IRG/WP 18-40832
Irvingia species are widely distributed in central and West Africa as well as parts of Asia and are earmarked for domestication due to the multitude of potential products that can be obtained from them. With renewed interest in renewable sources, the current study establishes the feasibility of utilizing extracts from Irvingia gabonensis and Irvingia wombolu kernels as wood adhesives. Proximate an...

Preventivephysical barriers against subterranean termites species for building protection: How to implement innovative materials to reach efficacy requirements
2018 - IRG/WP 18-40845
As the European regulation dealing with the use of biocides (BPR) for preventive protection of buildings against subterranean termites is leading to more and more pressure on physico-chemical barriers currently used (PT18), some existing developments are focusing attention on physical biocides-free barriers. The main target is then to avoid the use of active ingredients, to stay out of the BPR sco...

Promoting Commercially Available Epoxy Resins for Non-biocidal Wood Preservation
2019 - IRG/WP 19-40877
Commercially available epoxy and polyamine resins were evaluated with the aim of developing new non-biocidal wood preservation treatments. A simple method allowing the impregnation of wood by vacuum double impregnation followed by a curing process was developed for two reference species, beech Fagus sylvatica and Scots pine Pinus sylvestris. The tested products were evaluated for their ability to ...

Effects of preservative impregnations on wettability and surface free energy properties of Eucalyptus grandis wood
2023 - IRG/WP 23-40978
Wettability and surface free energy (SFE) are crucial parameters for evaluating the adhesion thermodynamics of solid surfaces. Hence, this study investigated the effects of copper azole (CA) and disodium octaborate tetrahydrate (DOT) preservative impregnations on Eucalyptus grandis wood wettability and SFE. Wettability was determined in terms of contact angles with polar (water) and non-polar (dii...
