Starch Based Adhesives Made from Durian Seed Through Dextrinization

Abstract

In order to utilize durian seeds waste, production of wood adhesive made from them was carried out. Method of dextrinization was applied and characterizations of the adhesive's properties were evaluated, namely specific gravity, viscosity, gel time, pH, clarity, color, and microscopic description including the particle's size of the adhesives. The properties were compared to other starch based adhesives, such as sago and tapioca. For further utilization as wood adhesive, application for particleboard binder was investigated. Parameter of internal bonding of the board then was evaluated. Result of this work showed fundamental properties of dextrin adhesive made of durian seed were similar with sago and tapioca's dextrin excluding the colour. Values of internal bonding of particleboard were varied that indicated many factors affected the quality of particleboard for instance the distribution of the adhesive.
