Utilization of Merban Wood Extract to Bind Laminated Bamboo Products

The report describes the use of adhesive made from merbau wood extract ( Spp ) which is allowed to copolymerize Intsia . with resorcinol, formaldehyde under alkaline conditions, and tapioca as an extender. The adhesive was used to manufacture three-ply composite board consisting of a back and core layers sengon ( ), and jabon made from Falcataria mollucana ( ), while the face layer was made either one of three bamboo species, namely, andong Anthocephalus chinensis ( ), mayan ( ), and bitung ( Gigantochloa pseudoarundinacea Gigantochloa robusta Dendrocalamus Kurz. asper .). Result shows that physical-mechanical properties of the composite board with using adhesive by Schult. F formula (% of weight ratio) Merbauextract : Resorcinol 50% : Formaldehyde 37% : Extender = 100 : 10 : 10 : 5)were similar with to those of products made of synthetic phenolic adhesive and classified as an exterior quality type with E or 0 F**** types of low formaldehyde emission
