1.1 BACKGROUND TO THE STUDY
Paint Factory or plant is an industrial site, usually consisting of buildings and machinery, or more commonly a complex having several buildings, where workers process raw materials into paint.
Factories arose with the introduction of machinery during the industrial revolution when the capital and space requirements became too great for cottage industry and workshops.
Paint is a subdivision of surface coating. It is a relatively opaque solid coating applied as thin layer whose films are usually formed by polymerization of polyunsaturated oil. However, other subdivisions of surface coating include: varnishes (clear coating), enamels (pigmented varnishes), lacquers (film formed by evaporation only), printing inks and polishes. Paints generally have very low thermal conductivity, electrically inert and can be washed and cleaned. The various raw materials for making paints include pigments, vehicle, alkyd resins, surfactants, solvents (thinners) and colouring matters.
