Çapa 1 ACETYLATION PROCESS How Does the Modified Wood Process Work? 1 Hydroxyl Groups Wood's Water Sensitivity Natural wood contains water-attracting hydroxyl groups, which cause swelling and shrinkage. Over time, this leads to deformation and reduced durability. 2 Acetyl Groups Natural Water Resistance By replacing hydroxyl groups with acetyl groups, wood becomes more water-resistant and stable, reducing the risk of swelling and rot. 3 Acetylation Chemical Transformation for Moisture Resistance Wood is treated with acetic anhydride, which chemically changes its structure to enhance moisture resistance, minimize swelling, and extend lifespan. 4 Acetylated Wood Maximum Durability & Sustainability Accoya retains the same elements as natural wood but with increased acetyl content, resulting in outstanding durability, minimal maintenance, and superior dimensional stability. Acetylated Wood Accoya The Foundation of Superior Durability Accoya gains exceptional durability, dimensional stability, and high resistance to decay compared to traditional wood through an innovative modification process called acetylation. This advanced technology strengthens the wood’s cellular structure permanently, minimizing swelling, shrinking, and deformation. Thanks to this innovative process, Accoya becomes a long-lasting wood solution backed by a 50-year warranty. Additionally, it stands out as an eco-friendly building material since it is produced from FSC® certified sustainable sources and contains no toxic substances. Developed with acetylation technology, Accoya sets a new standard in the construction industry in terms of sustainability, durability, and low maintenance requirements.
