Acetylated wood is known to be a durable and dimensional stable alternative for high performance materials, and has high potential for exterior timber structures. Research has shown that acetylated wood can be effectively bonded by various adhesive types. However, one of the most common used adhesives for timber constructions, Melamine Urea Formaldehyde (MUF), shows a high degree of delamination of the bond line in acetylated wood. A Norwegian project is investigating the use of glued acetylated wood (GlAceWood) for load-bearing constructions for application in service class 3. Poor wettability and remaining free acetic acid from the modification process influence the bonding to various degrees. The project aims to improve the bonding properties of acetylated softwood and hardwood by manipulating a MUF-based adhesive system.
