Wood preservative chemicals and coatings active ingredients are used to protect wood from the insects or fungus to increase the shelf-life of the wood. Chromated copper arsenate (CCA) wood preservatives have been used to protect wood from deterioration. Wood preservatives contain chromated arsenicals include preservatives containing copper, chromium, and arsenic. The primary purpose of preservation of wood is to increase its service life, thereby avoiding the need for frequent replacements adding to deforestation.
Wood preservative chemicals and coatings active ingredients offer resistance to degradation and destruction from living organism in wood. Celluloses, starches, hemicelluloses, and other susceptible materials are some fungi or insects that degrade the wood contents. However, these pests can easily be prevented from rotting and feeding on the wood by applying conservation treatment. Moreover, wood preservative chemicals and coatings active ingredients used to paint the wooden surfaces to provide aesthetic appeal and surface protection. These chemicals or ingredients also provide resistance to wear and tear from external environmental factors.
One of the most popular wood preservatives is boric acid, which is effective against fungi and bacteria. It prevents the growth of mould and spoilage on the surface of timber. Other types of preservatives that prevent the development of moisture-carried diseases in timber are organic bleaches and polymers. Bleaches and polymers are used for timber preservation, which help prevent decay, dermatitis, rot, insect infestation, and structural distortion caused by temperature fluctuations, shifts in humidity, and direct sunlight exposure.
CCA is registered with the U.S. Environmental Protection Agency (EPA) for the treatment of wood products that may be found in agricultural/commercial settings, as well as products found in residential settings. Moreover, EPA has classified all of the chemicals & their contaminants, as known or probable carcinogens.
