Applications

• Cleaning solvent for vapor degreasing, immersion cleaning and spray cleaning

• Solvent cleaner for heavy greases, oils, waxes, silicones and non-polar flux residues

• Lubricant deposition applications where increased solvency is desired

Comparison of Safety Profiles

Margin of safety is calculated by exposure guideline divided by exposure. The larger the safety margin, the safer the

product is in its intended use.

Regulations on Chlorine-Containing Solvents

Because of its favorable health and environmental properties, trans-1, 2-dichloroethylene (t-DCE) is subject to less

Engineered Fluid include volatile organic compound (VOC) emissions of t-DCE and reporting requirements if

t-DCE is emitted into water or if a spill of 1176 lbs. or more of Novec 73DE fluid occurs. t-DCE is not considered a

Hazardous Air Pollutant (HAP).
