Getting the Most from Our Forest Resource
Wood adhesives are important in helping use timber resources efficiently. As large trees become less available, the wood industry has developed new and innovative wood products as alternatives. Wood adhesives have made that possible. These new products can use smaller logs, less desirable species of wood, and even wood that would otherwise be burned or land-filled. These modern engineered products are manufactured from wood and as such they have structural characteristics similar to that of solid-sawn lumber. Because the natural defects of solid wood are removed in the manufacturing process, the structural properties are more uniform. The type of adhesive used to join the individual pieces could, however, affect their fire resistance.
What Adhesives Do
An adhesive is used to bond wood components such as veneer, strands, particles, and fibers. The adhesive must provide the required strength immediately after manufacture as well as for long-term use. Some of the adhesives used in modern wood products are suitable for exterior exposures.
