Abstract
Air-drying white paint based on palm stearin alkyd resin was prepared with conventional and nano-ZnO and ZnS pigments. The effects of used pigments on air-drying time and some physical-mechanical characteristics of the paint were investigated by comparing them with conventional counterparts. It was found that ZnS has little effect on the drying time of alkyd paints, and the time of paint drying does not depend very much on the volume concentration of this pigment. ZnO pigments had outstanding effects on drying time and physical–mechanical properties of the air-drying paints, but the best result was observed for paints containing nano–ZnO. Zinc-containing pigment systems, if composed of the nano-type, provide excellent results.
