Most of the trichloroethylene produced is used for metal degreasing. Other important uses are in the scouring of wool and as an extractive solvent, e.g. for olive and soya bean oils. Minor uses are as a heat transfer medium, anaesthetic, insecticide and fumigant, paint remover and fire extinguisher. 

Trisodium phosphate is strongly alkaline many of its appHcations depend on this property. For example, many heavy-duty cleaning compositions contain trisodium phosphate as a primary alkalinity source. The crystalline dodecahydrate itself is marketed as a cleaning compound and paint remover. Traditionally, trisodium phosphate has been used in water softening to remove polyvalent metal ions by precipitation as insoluble phosphates. Because the hypochlorite complex of trisodium phosphate provides solutions that are strongly alkaline and contain active chlorine, it is used in disinfectant cleaners, scouring powders, and automatic dishwashing formulations. 

Trichloroethylene is also known as Triclene and Vitran and by other trade names in industry. It is a nonflammable, colorless liquid at room temperature with a somewhat sweet odor and a sweet, burning taste. Trichloroethylene is now mainly used as a solvent to remove grease from metal parts. It is also used as a solvent in other ways and is used to make other chemicals. Trichloroethylene can also be found in some household products, including typewriter correction fluid, paint removers, adhesives, and spot removers. Most people can begin to smell trichloroethylene in air when there are around 100 parts of trichloroethylene per million parts of air (ppm). Further information on the physical and chemical properties of trichloroethylene can be found in Chapter 3, and further information on its production and use can be found in Chapter 4. 

For impact tests, ASTM-02794, a ball of known mass was dropped a fixed height through a tube, impacting the coated metal panel. Indirect impact resistance is reported as the fraction of paint removable (pickoff) from the impact site when the panel is struck on the uncoated side. Direct impact resistance is reported as the pickoff at the impact site when the panel is struck on the coated side. Optimally, no coating is loosened by this test. 

Uses Solvent for cellulose acetate, crude rubber, natural resins, nitrocellulose, vinyl resins, waxes, fats, oils, shellac, rubber, DDT, and other pesticides preparation of adipic acid and caprolactum additive in wood stains, paint, PVC paints, lacquers (to prevent blushing or improve flow), and varnish removers degreasing of metals spot remover lube oil additive in PVC adhesives to control evaporation rate leveling agent in dyeing and delustering silk. 

In the chemical industry and in research alone more than 1700 trade name products and chemicals are used as solvents (Ash and Ash, 1996). The worldwide solvents market is estimated at over 30 billions pounds per year. Solvents are used in a wide range of industries and applications including metal cleaning and degreasing, dry cleaning operations, automotive and aviation fuel additives, paints, varnishes, lacquers, paint removers, plastics and rubber products, adhesives, textiles, printing inks, pharmaceuticals, and food processing. 

Tetrachloroethane is used as a solvent, for cleansing and degreasing metals, in paint removers, varnishes, lacquers, photographic film, resins and waxes, extraction of oils and fats, as an alcohol denaturant, in organic synthesis, in insecticides, as a weedkiller and fumigant and as an intennediate in the manufacture of other chlorinated hydrocarbons (Lewis, 1993). 

Recommended Dilutions as is Applications Paint remover for wood and metal surfaces Notes Paint on with brush and remove with putty knife, steel wool, etc. 

The main uses of methylene chloride are in paint remover, aerosols, chemical processing, urethane foam blowing agents, metal degreasing, and electronics. 

Methylene chloride, a volatile chlorinated hydrocarbon, is used as a paint remover, metal degreaser, and aerosol propellant. The odor threshold for methylene chloride in the air is 100 ppm. According to Shelton (1989), it has been shown to induce tumors in mice. 

Oxalic acid is used in the manufacture of dyes, inks, bleaches, paint removers, varnishes, wood and metal cleaners, dextrin, cream of tartar, celluloid, tartaric acid, purified methyl alcohol, glycerol, and stable hydrogen cyanide. It is used in the following industries photographic, ceramic, metallurgic, rubber, leather, engraving, pharmaceutical, paper, and lithographic. 

Use Water softeners, boiler-water compounds, detergent, metal cleaner, textiles, manufacture of paper, laundering, tanning, sugar purification, photographic developers, paint removers, industrial cleaners, dietary supplement, buffer, emulsifier, food additive. 

Under certain conditions, dichloromethane (often the major constituent of chemical paint removers) can be converted into phosgene [238,747]. Tobacco smoke, exhaust gases from oil-fired furnaces or petrol engines, and hot metal surfaces are all reported to have a catalytic effect on the reaction [238] ... 

Trichloroethylene is widely used in industry for cleaning metal parts. It is also an ingredient in adhesives, paint removers, typewriter correction fluids, and spot removers. Its water solubility (1 g/L) ensures that, if contamination occurs near a water source, it is possible it will be present in drinking water at unacceptable levels. 

Methylene chloride (CH2CI2) is used as an aerosol propellant, paint remover, and a blowing agent in polymers. It also is used as a solvent in the metals and in the electronics industry. Methyl chloride will react with benzene to form dimethyldibenzyl methane, an ingredient in the perfume industry because of its orange color [159].

Tribasic sodium phosphate is used in a variety of cleaning agents, such as detergents, industrial cleaning products, and metal cleaners to treat boiler water for the tanning of leather in the manufacture of textiles and paper products in the purification of sugar as a dietary supplement for humans and farm animals in paint removers and for various photographic purposes. 

MAJOR USES Used in the production of paint removers, resins, waxes, insecticides, weed killers, fumigants, trichloroethylene and tetrachloroethylene photographic development degreasing and cleaning of metals. 

MAJOR USES Used in manufacture of paint removers, adhesives, typewriter correction fluid refrigerant degreaser of metal parts used as an extraction solvent in greases, oils, fats, waxes, tars. 

OTHER COMMENTS used as a solvent in paint removers and as a solvent for cellulose acetate vapor degreasing solvent for metals and plastics major use as a solvent and cleaning agent in the chemical processing industry used in the pharmaceutical industry as a solvent in the production of antibiotics, steroids, and vitamins chemical intermediate for bromochlo-romethane.
