      Аннотация: Increasing student skills in the field work, and linking theory with application, become the motivation to students to join to factories and companies for achieving this target. One of chemical process industries is the paints industry. Paints is a main part of coatings, paints composed of five components which are; resin (binder), solvent, filler, pigments, and additives.From the point of view of chemical engineering; paints manufacturing, requires number of unit operation which are mixing, milling, and filtration. These of operations done using several industrial units which are; mixers, mills, and screen filters.Paints manufacturing done by adding binders, solvents, and thickeners to provide a gel phase which its existence is a mark for starting of adding fillers and pigment, through and after manufacturing processes a samples send to laboratory to done some tests, by which the manufacturer be sure from his products quality, the main tests are density, viscosity, and hiding power test, there several tests can be done also such as wash-ability and impact test.
