First comes the pretreatment stage. After rust removal and alkaline degreasing, a zinc phosphate formulated pretreatment (see Section 15.2) is applied by dip or spray-dip. Crystalline iron-rich zinc phosphate forms on the metal surface at a coating weight of 0.5-4.5 g/m. ... 

Degreasing small parts can be achieved with solvent sprays. Chlorinated hydrocarbons such as trichloroethylene (tricho) are sometimes used, normally in a heated vapor bath, although special handling, solvent recovery, and disposal methods are required. 

The solution was applied to the surface of cold-rolled steel, dip-galvanized steel sheet, and aluminum strip for degreasing and passivating in a single operation at 40°C for 90 s. The surfaces were then lacquered (85-100 pm thickness) and tested in a salt-spray test for 480 h without showing subsurface migration and blistering. The method is especially useful in the automobile industry for coated sheet [191]. 

Roy Plunkett did not set out to invent Teflon. He discovered this polymer by accident while working in a lab in 1938. Plunkett was trying to make a new chlorofluorocarbon (CFC)—a chemical compound that contains chlorine, fluorine, and carbon and used to be a common ingredient in aerosol spray propellants, degreasing agents, foam packing material, and refrigerants. 

A solvent is a substance that can dissolve another substance, and a volatile solvent is a liquid that vaporizes at room temperature. Volatile solvents include adhesives such as airplane glue and rubber cement aerosols such as spray paint, hair spray, and air freshener solvents such as nail polish remover, paint remover, and lighter fluid and cleaners such as dry cleaning fluid, spot remover, and degreasers. 

Uses 1,1,1-Trichloroethane is a colorless, nonflammable liquid with a sweet smell similar to that of chloroform. It is absorbed by the system mainly by inhalation but also can penetrate the skin. 1,1,1-Trichloroethane does not occur naturally in the environment. It is found in many common products such as glue, paint, industrial degreasers, and aerosol sprays. In view of its impact on the ozone layer, all attempts have been made to stop its production in different countries of the world.116 1163 125... 

Trichloroethylene and 1,1,1-trichloroethane are used in correction fluids, dry-cleaning products, degreasing sprays, and solvents and spot removers. Bromochlorodifluoro-methane is a compound found in halon fire extinguishers that is abused. Freon is used for refrigeration and air conditioning systems. Anesthetics include halothane, chloroform, and the local anesthetic ethyl chloride. Methylene chloride is a component of rubber cement, paint strippers, and degreasing agents, and fluorocarbons are present in many types of aerosol sprays.
