Preliminary investigation of the durability and performance of 1,3-dimethylol-4,5-dihydroxyethylene urea (DMDHEU) treated aspen strandboard
2024 - IRG/WP 24-30804
Wood modification technologies are growing in popularity because of their potential to improve wood properties by permanent covalent chemical modifications rather than chemical impregnation. These features can be utilized in wood composites to help improve dimensional stability and composite resistance to fungal decay. In this study, 1,3-dimethylol-4,5-dihydroxyethylene urea (DMDHEU) was used to m...

Influence of the substitution of phenol with lignin cleavage products in phenol-formaldehyde impregnation resins for wood modification on the fungal decay resistance and impregnation depth
2024 - IRG/WP 24-30805
The impregnation modification of wood with phenol-formaldehyde (PF) resins increases the woods dimensional stability and resistance against fungal decay. However, to decrease the usage of non-renewable resources, the substitution of phenol has been a topic of scientific interest. Lignin is a currently underutilized resource with a chemical structure that contains phenolic units. For adhesive appli...
