2. The ”Achilles Heel” of wood
o Dimensionally unstable
o Poor microbial and insect durability
Acetylated wood offers a solution

3. The Acetylation Process
o Acetylation transforms accessible hydroxyl groups in wood to
acetyl groups
o Reduction in “bound water” content dimensional stability
o Wood is no longer food source for microorganisms
