Thinners for paints

Cumene in minor amounts is used as a thinner for paints, enamels, and lacquers and to produce acetophenone, the chemical intermediate dicumylperoxide, and diisoprop5lben2ene. It is also a good solvent for fats and resins and, as such, has been suggested as a replacement for ben2ene in many of its industrial appHcations (22).

Use and exposure There are three forms of xylene meto-xylene, ortho-xyltnt, and para-xylene (m-, o-, and p-xylene). These different forms are referred to as isomers. Xylene is a colorless, sweet-smelling liquid that catches tire easily. It occurs naturally in petroleum and coal tar. Chemical industries produce xylene from petroleum. Xylene is used as a solvent in the printing, rubber, and leather industries. It is also used as a cleaning agent, a thinner for paint, and in paints and varnishes. It is found in small amounts in airplane fuel and gasoline. Xylene is used extensively in the manufacture of many other chemicals, such as plastics, synthetic fibers, pesticides, insect repellents, and leather goods. ...

Small amounts of cumene are used as thinners for paints, lacquers, and enamels, and as solvents in paints and other types of coatings. By far the greatest amount of cumene, however, is used as a raw material in the manufacture of phenol, acetone, and methyl styrene. These compounds, in turn, have a great many chemical and industrial uses. Some of the most important uses are the production of plastics, such as polystyrene, phenol-formaldehyde resins, and polycarbonates.

Uses Toluene is a clear, colorless, flammable, and sweet- pungent-smelling liquid. It is extensively used as a solvent in different industries, (e.g., rubber chemical manufacture, drugs and pharmaceuticals, thinner for inks, paints dyes, perfume manufacture). 

Turpentine. Turpentine is used directly as a solvent, thinner, or additive for paints, varnishes, enamels, waxes, polishes, disinfectants, soaps, pharmaceuticals, wood stains, sealing wax, inks, and crayons, and as a general solvent. The chemistry of its mono-terpenes offers many possibilities for conversion to other substances, as illustrated in Fig. 28.20. There is increasing use of turpentine to produce fine chemicals for flavors and fragrances. An important use of turpentine is in conversion by mineral acids to synthetic pine oil. It also is a raw material for making terpin hydrate, resins, camphene, insecticides, and other useful commodities. These uses are included in the following summary of its applications. 

Coverage. The spreading rate, expressed in square meters per liter. Poor coverage is a defect related to either sticky application because the viscosity of the paint is too high, resulting in too much paint being applied, or to an absorbent substrate. In the latter case, reduction with the appropriate thinner for the first coat only will provide the remedy. 

Solvents or thinners control paint consistency and application properties. Slow solvents evaporate slowly and leave the film open (workable) for longer periods than fast solvents, which evaporate rapidly in water-thinned paints, water is the thinner and there is no control over rate of evaporation. 

Undifferentiated connective tissue disease (UCTD) is a term used to describe conditions where people have symptoms and laboratory test results that resemble known musculoskeletal diseases such as SS and SSc, but do not have enough of the symptoms to meet the requirement for a well-defined diagnosis of a single disease. A study of patients with UCTD found statistically significant associations with exposures to paint thinners and paint removers.1311... 

The hazardous waste issues will decrease with the reduction of the hazardous waste generation below 22001b/mo from 45271b/mo. By use of the previous recommendations and with the possibility that sludge may be recovered with thinner, the reduction can be significant. This will reduce the burden on the facility as well as the cost for paint and hazardous waste disposal. The cost reduction for hazardous waste disposal is estimated to be 25,550/yr. This cost reduction is affected by the reduction in evaporated paint and reduced sludge loss. 

Choice of substance can make a difference. Although most any substance (and activity) can become psychologically addictive, only some tend to become physically addictive. Stimulants (cocaine, for example), depressants (alcohol, for example), and narcotics (heroin, for example) are more likely to become physically addicting than inhalants (paint thinner, for example) or hallucinogens (LSD, for example). Whether marijuana can be physically addictive seems open to debate (it meets the criterion of tolerance but not withdrawal, see "physical addiction" on page 53). 

Kerosene — A flammable oil characterized by a relatively low viscosity, specific gravity of approximately 0.8, and flash point close to 55°C. Kerosene lies between the gasolines and fuel oils in terms of major physical properties and is separated from these products during the fractional distillation of crude oils. Kerosene is used for wick lamps, domestic heaters and furnaces, fuel or fuel components for jet aircraft engines, and thinner in paints and insecticide emulsions. (See also Jet fuel.)...
