Abstract:

Potato peels were obtained from bean cake (akara) sellers at Sabon Gari metropolis of Zaria LGA, Kaduna State, Nigeria. Starch was extracted from the peels and the starch was used for the production of the adhesive. The adhesive produced was characterized based on the following physical properties: pH, density, viscosity, curing time, bond strength, and shelf life. Commercial synthetic adhesive was used as a control to compared with the produced starch-based adhesive. The result revealed the pH of the starch-based and commercial synthetic adhesives were the same (7.00), their densities were 1.09 and 1.19 g/ml respectively. The viscosity of the starch-based and commercial synthetic adhesives are 10.9 pa.s and 10.1 pa.s, their curing time was 20 and 15mins respectively, their bond strength was 26.72 and 27.09Nmm-2 respectively. Both adhesives showed no signs of deterioration after 4weeks of storage. The findings from the result of this research suggests that the working properties of the starch-based adhesive produced compared favourably with the synthetic adhesive sold commercially. This however, indicates that starch-based adhesive can to some extent be a good replacement for synthetic adhesives in bonding of footwear upper components such as light leather, fabrics, etc. and other articles such as paper and fiberboard. Furthermore, it is recommended that further research should be carried on starch-based adhesive to improve its working properties and shelf life in order to replace the synthetic adhesives and thus prevent the environmental and health hazard posse by the synthetic adhesives sold commercially.
