Abstract

Waste expanded polystyrene was dissolved in toluene and used as a binder for an emulsion paint formulation and also snail shell was ground to powder and used as a filler for replacement of PVA and CaCO3 respectively, in five different proportions, the filler loading A, B, C, D and E. The iso – 12944 standard emulsion paint formulation and method of production was employed. All the five samples gave good quality emulsion paint in terms of density, drying time and pH except for samples A and B with pH 8 which is within the range where bacteria strive. Samples A, B, D and E had better rub fastness. However, the situation was observed that the paint viscosity decreased with increase in EPS. The higher the EPS and water content, the lower the viscosity of the paint produced. This study has found EPS solution as a potential binder and snail shell as filler in the coating industry.
