Xyloid: A Wood Preservative for Outdoor Applications

Xyloid is a brand name for a type of wood preservative that contains copper napthenate as the active ingredient. It is used to protect wood from decay and insect damage, particularly in outdoor applications such as decks, fences, and playground equipment. Copper napthenate is a complex of copper ions and naphthenic acid, which is a type of fatty acid. The exact mechanism of how xyloid works is not well understood, but it is thought to involve the release of copper ions into the wood, where they disrupt the growth of fungi and insects. Xyloid is considered to be effective against a wide range of decay-causing organisms, including fungi, bacteria, and insects. It is typically applied to the wood as a liquid solution, and it can be used in combination with other preservatives or finishes to provide additional protection.
