Nigeria produces four grades of Acacia species in commercial quantities which are not used for local
industrial applications but exported for foreign earnings. The grades 1 and 2 that are preferred by exporter
countries are used in the pharmaceutical, confectionary, food, textile and beverage industries. Nigerian
foundries use imported materials for binding their synthetic casting sands due to non development of locally
available materials like Acacia species exudates. This research investigated physical and chemical properties
of Nigerian Acacia species to determine its viability for binding sand. Standard experimental tests and
equipment were used in laboratories of the National Research Institute for Chemical Technology and National
Research Institute for Leather Technology, Zaria to determine the melting point, optical rotation, specific
gravity, water solubility, PH, moisture/volatile matter, metal/sulphate ion content and macro-structural analyses
of each grade of the Nigerian Acacia species. In comparison w ith foundry requirements it satisfies major
physiochemical properties desired of good sand binders. The material can be investigated further for mechanical
properties as potential high quality sand binder for Nigerian foundries.
