Production of Emulsion Paint with the Available Materials
This project is on the production of paint from the available materials. The first process involved sourcing the available material, which includes calcium carbonate (detonate) water etc. The next step is the proper production procedure. The same product patterns were employed while the production was valued to obtain high-quality paint.
From the result obtained, it was observed that high-quality paint was produced in production category C(3), consisting of 10kg water, 0.1kg titanium dioxide (TiO2), 0.3kg taleranol, 0-3 ethylene glycol, 0.3kg welting agent, 0.1kg defrayer, 0.2kg thickness 10kg CaCO3, 4kg PVA, 2kg NH3 and 0.5kg white spirit.
The above fact was ascertained by subjecting the various paint produced from different production procedures to quality control tests. The quality of this paint in production category C(3) was opacity 2 coat, PH 8, drying time 1 hour, chalking 190 cycle scrubs, PVA 20%, viscosity 3.8 poises, and binder gravity 1.17, and its quality marched with the Standard Organization of Nigeria (SON) approved quality.

Standard quality of paint
Until recently, paint production was regarded as art, and use was made of it principally for decorative purposes. The production then was by trial and error with no standard principle and little or no regard for the quality of the final product. With the application of science in the production of paint, a product of high quality is now possible. This time, it does not only give appearance but, more importantly, surface protection. Thus, the modern paint industry firm a small but essential part of the chemical industry. It is closely related to the plastics and petroleum industries and, like them, is based on modern chemistry, physics, and engineering knowledge.
THE PURPOSE OF THE PROJECT RESEARCH WORK
The purpose of this work is to make use of available source materials in the production of Emulsion Paint, test the properties of the paint and its performance against weather, and thus set a standard for future works.
THE SCOPE OF THE PROJECT RESEARCH
Paints are classified according to their application and functions, ie. Varnishers, leaguers, fillers, etc. Emulsion paint is water-based paint used for external and internal surface coatings, mostly in building for appearance and as a surface protector. Besides their protective action, varnishers and leaguers increase the protective action of manufactured goods.
The process involved in paint production, qualities, and performances of emulsion paint, in particular, is mainly dependent on the properties of its constituents. The ratios of these constitutions include pigments, pigment extenders, additives, and vehicles. Failure to make proper formulation before production causes deterioration and film degradation.
Emulsion paint production from available materials must meet the present need for a high-performance standard to cater satisfactorily to the needs of society at a particular point in time and to demonstrate a credible record of an ability to challenge external and future influences.
