Solvents in Paint Removers

Solvents used for paint removal are able to dissolve or considerably swell physically drying binders (e.g., vinyl chloride copolymers, cellulose nitrate, polyacrylates) and chemically cross-linked coatings (e.g., oil-based paints, dried alkyd resins, cross-linked polyester-melamine resins, cross-linked epoxy and isocyanate coatings) [14.237]. A combination of dichloromethane with low-boiling ketones or esters is particularly suitable. Small amounts of high-boiling solvents with a low volatility (e.g., tetrahydronaphthalene, solvent naphtha, methyl benzyl alcohol, or benzyl alcohol) are added to these mixtures to retard evaporation and increase the solvency. Modern paint removers do not contain chlorinated hydrocarbons, they are formulated on the basis of high boilers (e.g., dimethylformamide, dimethyl sulfoxide, propylene carbonate, and yV-methylpyrrolidone) in combination with alcohols and aromatics, or consist of aqueous, frequently alkaline or acidic systems.

Dichloromethane is used principally as a solvent, in paint removers, degreasers and aerosol products, and in the manufacture of foam polymers. Widespread exposure occurs during the production and industrial use of dichloromethane and during the use of a variety of consumer products containing dichloromethane. Substantial losses to the environment lead to ubiquitous low-level exposures from ambient air and water. 

USE Denaturant for ethanol, mfg flotation agents, flavors, perfumes as solvent in paint removers. Octane booster in gasoline. 

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. 

Trichloroethylene [79-01-6] ( Tri ) is insoluble in water, but is miscible with organic solvents. It dissolves fats, oil, waxes, rubber, and many resins it is used as a solvent and extracting agent. In paints, trichloroethylene raises the flash point, and is used as a solvent in paint removal pastes. It is increasingly being replaced by other systems for environmental protection reasons. 

Other. 2-Nitro-1-butanol is an excellent solvent for many polyamide resins, cellulose acetate butyrate, and ethylceUulose. It can be utilized in paint removers for epoxy-based coatings. 2-Hydroxymethyl-2-nitro-l,3-propanediol is usebil for control of odors in chemical toilets. Its slow release of formaldehyde ensures prolonged action to control odor, and there is no reodorant problem which sometimes is associated with the use of free formaldehyde. 2-Hydroxymethyl-2-nitro-l,3-propanediol solutions are effective preservative and embalming fluids. The slow Uberation of formaldehyde permits thorough penetration of the tissues before hardening. 

The major use of sec-butanol is to produce MEK by dehydrogenation, as mentioned earlier. 2-Butanol is also used as a solvent, a paint remover, and an intermediate in organic synthesis. 

Several epidemiologic studies of scleroderma, undifferentiated connective tissue disease, and multiple sclerosis suggest modest associations with any solvents or with organic or chlorinated solvents Trichloroethylene, paint removers, and mineral spirits are some of the specific solvents implicated in these studies.

Butoxyethanol acetate can pass into air from water and soil. It is directly released to the atmosphere by evaporation while it is being used as a solvent in paints, lacquers, thinners, inks, ink and spot removers, and resins. 2-Butoxyethanol acetate probably exists almost entirely as a vapor in outdoor air. It can be removed from the air by precipitation because it is moderately soluble in water. In air, 2-butoxyethanol acetate may also break down to other compounds...
