In the quest to develop sustainable materials for the coating industries, the surface coating potentials of two Nigerian local clays were evaluated in alkyd paints. The highly import-dependent coating industry in Nigeria gulps over N10b annually on materials that can be sourced locally, therefore, developing technically, and economically viable extenders for use in coatings, and thus, bringing down the cost of painting to acceptable limits in line with the sustainable development goals is very important. The local clays were analytically evaluated to study their chemical composition, structural morphology and physico-chemical properties. Alkyd paint samples were prepared using the clays, the clays containing varying amounts of TiO2 pigment and xylene as solvent. Analysis on the local clays revealed that they are inorganic silty clays, moderately acidic, and containing over 32% grains of size < 0.150 mm. The major compositions of the clays are SiO2 and Al2O3 in that order, with small amounts of TiO2 and Fe2O3. Paint sample formulated using TiO2 pigment only had the least viscosity value while the 100% Obowo clay formulated paint sample exhibited the highest viscosity value among the alkyd paint samples studied. The formulated paint samples shaded their colours on exposure to rain and sunlight, with only 100% Obowo clay paint formulation losing its adhesion after exposure. The alkyd paint dry film samples generally performed well in distilled water, 2% Na2CO3, and 2% H2SO4. The present study has demonstrated the utility of Obowo, and Ihitte-Uboma clays in formulating alkyd paints and shown they possess properties equivalent to the expensive imported extender pigments. The expectation is that these clays should find utilizations in the surface coatings industry which will help to reduce the over dependence on imported extender pigments. The clays are easy to process, stable and indigenously available.
