| Popis: | Three local extenders obtained from three different locations in the Akure area of Ondo State, Nigeria earlier processed, characterized and reported were used to produce interior decorative emulsion paints of Pigment Volume Concentration within the range of 74 – 76 %. Tests were carried out on the produced paint samples to ascertain their homogeneity, pH, specific gravity, viscosity, opacity, resistance to abrasion, resistance to external exposure, water dropping, dry times, fineness, temperature stability, colour, application properties, resistance to fungal and bacterial attack, application properties, re-coating properties, dry film resistance to fungal growth, adhesion to substrate, chalking, checking and cracking, flooding and floating and settling resistance. The properties of the paints produced with the local extenders were compared with those of the paint produced with commercial kaolin as extender and all properties of the paints were compared with the standard requirements stipulated by the NIS 269:2008 Standard. Results showed that the properties of the paints made with the local extenders met the required service requirements. The paints made with the local extenders offered better opacity on morest chart and substrate as well as higher abrasion resistance when compared with the paint made with commercial kaolin as extender. |
