Study on the Anticorrosive Behavior of New Hygiene Structured Pigment Based on Waste Core and Nano Shell in Alkyd Paints

Abstract

All the employed pigments, extenders, resins, solvents, additives and chemicals were products of different local and international companies. Silica fume waste was obtained from ferrosilicon factories in Aswan, Egypt. Its chemical composition is represented in Table (1), the waste was collected from the chimneys of the factory and this may be the cause of its gray color as it contains a very high percentage of carbon resulting from the smelting of this alloy preparation.
