Effect of extractives on gluability of wood. I. Gluability of some tropical woods after solvent extraction


, : Effect of extractives on gluability of wood. I. Gluability of some tropical woods after solvent extraction. Journal of the Faculty of Agriculture, Tottori University ( 26): 19-28

Wood extractives of apitong (Dipterocarpus spp.), teak (Tectona grandis), karin (Dipterocarpus macrocarpus) and bubinga (Guibourtia tessmanii) were removed by solvent extraction (using either n-hexane or a 2:1 mixture of ethanol and benzene) in a study to determine whether removal of extractives would improve gluability. Wood block samples, treated and untreated, were bonded with isocyanate, resorcinol and polyvinyl acetate resins and their glue bond strength properties were investigated.
