This proprietary acetylation technology developed by Eastman creates wood that is long-lasting and change-resistant. Simply put, we modify the wood throughout, increasing its dimensional stability – resulting in three times more resistance to shrinking and swelling. It means acetylated wood warps, bows, and cups less over the life of the wood. Best of all, acetylated wood looks and works like beautiful, real wood. The durability is real. The applications are endless. The potential is revolutionary.
