Comparative Analysis of Different Carboneous Waste for the Formulation of Erasable Ink for White Board Marker Refill

This article is aimed at carrying out comparative analysis of prepared erasable ink from locally sourced carboneous wastes (lampblack, tyre and coconut shell soot). Different formulation and modification were adapted in this research with effect to three different pigments for the produced inksusing non- oleoresinous varnish preparation method for the assessment and evaluation of the physiochemical properties. Standard test methods for adhesion, viscosity, opacity, drying time, erasability, eligibility were done on the formulated samples as described by SONS 1990.It was found that the size and shape of the pigment particles affects the colorstrength, hue, saturation, viscosity as well as other properties. Increasing gum Arabic increases viscosity which is inversely proportional to the drying time and as seen to give the ink a better performance and stability. This work is hoped to profferalternative sources of pigment in ink formulation.
