ABSTRACT

The use of adhesives for wood obtained from natural renewable sources comes from the beginning of human technological development. Nonetheless, due to some of its disadvantages such as low durability and low water resistance, sustainable adhesives rapidly lost ground. This situation has resulted in introduction of synthetic resins in the market. These resins captured the market, because they have better mechanical properties and high resistance to humidity. However, synthetic adhesives are based on non-renewable resources of petroleum and natural gas. They not only generate a large uncertainties in terms of the source availability, in the long-term but in some cases could represent a risk to the human health. Thus, in this chapter, suggested another source of raw material for adhesive wood production has been: the rosin obtained directly from trees. Since rosin can be obtained from a large number of tree species in almost all the continents, are a source of the rosin, as an alternative source for commercial adhesive production.
