Cleaning Fluids

71DA fluid is a hydrofluoroether in an azeotropic formulation with trans-1,2-dichloroethylene and ethanol. Its increased solvency and low surface tension, as well as nonflammability and constant composition during boiling, make it ideal for immersion defluxing and degreasing applications. In addition, the ethanol component of 71DA fluid provides enhanced removal of ionic contaminants.

71DA fluid is non-ozone-depleting, has a low global warming potential and a short atmospheric lifetime. It is low in toxicity and is listed as "acceptable without restrictions" under the U.S. EPA's Significant New Alternatives Policy (SNAP) program.
