MANGROVE TANNIN AS AN ADHESIVE FOR WOOD-BASED PANELS

Abstract

Laboratory investigations on tannin extracted from mangrove bark for the production of adhesive in wood-based panels showed encouraging results. The tannin was found to be reactive and combined well with phenolic resins in the manufacture of plywood and particleboard. Satisfactory bond quality was obtained using a glue mixture comprising 70% mangrove bark extract and 30% phenol formaldehyde in the adhesive formulation of plywood.
