As trichloroethylene and other solvents come under increased scrutiny for their health and environmental impacts, solvent users are left seeking more sustainable operating alternatives. In response, the use of toxic solvents to clean contaminants from metal parts has given way to aqueous-based options.
Alternatives to solvents have emerged largely due to ongoing regulatory recognition of their potential health and environmental liabilities. Traditional solvents are flammable, emit volatile organic compounds (VOCs) and can be hazardous to use. Depending on its chemical constituents, a solvent may be classified as a hazardous material that requires special handling, recycling and disposal procedures. These requirements increase the cost of solvent use and can raise liability risks.
A preferred option is the use of aqueous-based cleaners, which are non-flammable, pose lower health risks and Continue Reading
