JORGE, Fernando Caldeira et al. Métodos de Extracção de Taninos e de Preparação de Adesivos para Derivados de Madeira: Uma Revisão. Silva Lus. [online]. 2002, vol.10, n.1, pp.101-109. ISSN 0870-6352.

With the objective of increasing the use and value of maritime pine bark in Portugal, which is an abundant residue, this paper reviews several methods for the extraction of tannin-rich extracts from the bark or heartwood of some forest species, with an emphasis on pine bark. The utilisations of such extracts are discussed as applied to the preparation of adhesives for wood and wood-derivatives, including resins based solely on these extracts, with extract and synthetic resin, with cold set resins and as formaldehyde scavengers.

Palabras clave : tannins; extraction; adhesives; review.
