Chlorinated Solvents and Replacements
METHYLENE CHLORIDE

Uses: Paint, varnish & carbon removers, solvent degreasing, blowing agent in foams, extraction medium in food and pharmaceutical processes, solvent for cellulose acetate, solvent and flammability suppressor in aerosol formulation, bitumen testing.
Process solvent for plastics in polycarbonate production, cellulose esters, triacetate fibre production and triacetate films.

TRICHLOROETHYLENE

Uses: Metal degreasing; extraction solvent for oils, fats, waxes; solvent dyeing; dry cleaning; refrigerant and heat exchange liquid; fumigant; cleaning and drying electronic parts; diluent in paints and adhesives; textile processing; chemical intermediate and for flushing liquid oxygen systems.

The best alternative which should be considered as the "drop in replacement" for this product is Highly Stabilised Methylene Chloride.

PERCHLOROETHYLENE
Uses:  Dry-cleaning solvent for garments, highly stabilised versions used as vapour degreasing solvent, drying agent for metals and certain other solids, vermifuge, heat-transfer medium, manufacture of fluorocarbons.
1,1,1, TRICHLOROETHANE 

Uses:  Solvent for vapour and cold cleaning of precision components prior to further processes such as plating or painting, PCB defluxing.

The product ceased manufacture in the latter part of 1995 as it was to be phased out under the Montreal Protocols on Ozone Depletion as it was alleged to damage the Earth's Ozone layer.

The withdrawal of this product has posed problems for engineering users who used it for the cold cleaning of precision components as it was moderately volatile, left no residue on evaporation and was safer to use than the other volatile solvents commonly in use for small parts cleaning on the bench. As the product was non-flammable it replaced solvents such as Acetone, M.E.K. and I.P.A. all of which have a flashpoint.

The best alternatives which should be considered as the "drop in replacement" for this product come from the many n-propyl bromide based solvent ranges.
