Solvent Cleaning and Vapor Degreasing

Novec fluids are a safer alternative to n-propyl bromide (nPB) and trichloroethylene (TCE) because of their high margin of safety. Typical vapour degreaser exposure is 10 ppm and all Novec fluids have a safety margin wide enough for workers to safely use them in this application. In contrast, in order to safely use nPB in vapour degreasing, worker exposure levels need to be reduced to 0.1 ppm, which is 100x lower than typical exposure levels.

Unlike many other cleaning and vapour degreasing solvents, Novec fluids are environmentally sustainable and are not scheduled for regulatory phasedown. Under the U.S. EPA’s SNAP program, they are acceptable substitutes in metals, electronics and precision cleaning applications based on their zero ODP, low GWP, low toxicity and non-flammability. Neat Novec fluids are also exempt from the EPA’s definitions for Volatile Organic Compounds (VOCs).

Because of their low surface tension, Novec fluids can penetrate tight spaces and thoroughly clean hard-to-reach areas. They evaporate quickly without leaving residue, which means parts get clean faster and costly “drag out” solvent losses are reduced. Together, these properties make them a smart choice for a variety of cleaning processes, from light-duty to heavy-duty and everything in between.
