The term wood preservatives defines that the wood preservation is the process of preserving
wood from the wood destroying agents like insects or fungus so that the life span of the wood
can be extended. It refers to the treatment of wood with chemicals to impart resistance to
degradation and deterioration by living organisms. The proper application of chemical
preservatives can protect wood from decay, and stain fungi, insects and marine borers, thus
prolonging the service life of woods for many years.
The wood contents celluloses, hemicelluloses, starches and other susceptible materials that
attract the fungi and insects to be degraded and eaten. After the preservative treatments, the
fungi and insects cannot decompose and feed on these substances, hence the durability of
wood is to be increased.
