ABSTRACT

The major aim of this project research work is to produce emulsion paint from locally sourced pigment & extenders.

The materials used for the production was of local source.

The major raw materials used for the production of the emulsion paint: water, titanium iv oxide, calcium carbonate, kaoline, calgon, natrosol, biocide P.V.A, ammonia, deformer (Ginap) kerosene, yellow iron oxide and red iron oxide.

Emulsion paint of two (2) samples was produced, and calcium carbonate locally obtained was used in larger quantity in order to reduce the cost of production of the paint with little of the expensive titanium iv oxide added.

The first sample was a creamy white colour paint, while the second sample has a result of the mixture of blending of locally sourced yellow iron oxide and red iron oxide. Pigment, that was added to it. The two (2) samples gave high quality emulsion paints in terms of its brush ability, opacity, coverage, stability etc.

Quality control test carried out on the two (2) samples of emulsion paint showed that the local pigment and extenders used (titanium iv oxide, calcium trioxocarbonate iv, kaoline, yellow iron oxide and red iron oxide) fitted in so well in the paints to give the necessary adhesion, opacity and coverage, with excellent binding effect observed.
