More specifically, acetylation targets free hydroxyls, an abundance of chemical groups contained within the wood. Free hydroxyl groups readily absorb and release water according to changes in the climatic conditions to which the wood is exposed, which is the main reason why wood swells and shrinks.

The acetylation process modifies the wood to its core. Therefore, unlike pressure-treated wood, it can be cut or profiled without exposing unprotected surfaces. Further, since acetylation is non-reversible, there is no risk of leaching or loss. Due to these characteristics, acetylated wood is appropriate for a number of exterior applications, including:

decking;
cladding;
windows;
; and
structural projects, such as bridges.
The technology behind the acetylation process is different for each species; it is rcs data currently being used for radiata pine.

Better wood through chemistry
The acetylation process alters the wood’s reaction with water by permanently replacing those free hydroxyls with stable acetyl groups that will not bond with water. With a higher level of acetyl molecules, the shrink/swell cycle is improved by 70 percent or more.
