DEVELOPMENT OF EMULSION PAINT USING HYDROXYLATED AVOCADO SEED OIL MODIFIED POLYVINYL ACETATE COPOLYMER AS A BINDER

A.B. Abubakar, J. A. Gidigbi

Abstract


The study explored the use of modified Polyvinyl acetate (PVAc) binder to produce emulsion paint. Hydroxylated Avocado seed oil (HASO) was extracted manually, and subsequently copolymerised with conventional polyvinyl acetate. The result of this physico-chemical properties of HASO/PVAc copolymer resin were in conformity with the literature values, and the standard. The result of physical properties of the copolymer resin (HASO/PVAc) analysed, shows better improvement in water resistant, flexibility and better packaging density, as against conventional PVAc binder. The results of the physico-chemical analysis of the emulsion paint formulated with HASO/PVAc copolymer resin show improved physico-chemical properties when compared with paint formulated from conventional PVAc, and the standard acceptable values. The paint formulated from the copolymer resin shows better performance in physical parameters such as pH, the Viscosity, Flexibility, Adhesion, Opacity, Hardness test, Tackiness. It also exhibit better resistance to blistering; acidic, alkaline and salt medium compared to the paint made from conventional PVAc.
