In the finishing industry today, the most common cleaning system is based on water technology. Since the move away from the two most common vapor degreasing solvents (CFC113 and 1-1-1-trichloroethane) over the past decade due to suspected ozone depletion, aqueous cleaning has become a tried-and-true process. But aqueous cleaning systems tend to have large footprints,…

“nPB” is an abbreviation for “Normal Propyl Bromide” or “1-bromo-propane” indicated by the CAS #‎106-94-5 on Safety Data Sheets.  It replaced ozone depleting Freon and 1-1-1 Trichloroethane.It is a relatively inexpensive, nonflammable, versatile chemical that removes many types of contamination, such as oils, grease and fluxes. It was formerly used in aerosol cleaners, but due to environmental restirctions,…

In the finishing industry today, the most common precision cleaning system is based on water technology. This is understandable, because aqueous cleaning has become a tried-and-true process since the elimination of common vapor degreasing solvents due to suspected ozone depletion. But aqueous cleaning systems tend to have large footprints, require significant capital investment, guzzle electricity…

Viscosity is a chemical characteristic that describes a fluids ability to flow quickly, smoothly and without outside effort.  It is an indirect measure of the molecular attraction within a fluid for itself; highly viscous fluids are strongly attracted to their own molecules and resist separation.In terms of critical cleaning, highly viscous fluids are not very good cleaners…

Fluid mechanics is the study of how fluids move, and one of the most important parameters of fluids is their viscosity. Most people think of “viscosity” in terms of a fluid’s ability to flow. Chemists have a slightly different feel for the phenomenon; viscosity is defined as its resistance to gradual deformation. This corresponds to…

nPB is an abbreviation for “Normal Propyl Bromide” or “1-bromo-propane” indicated by the CAS #‎106-94-5 on Safety Data Sheets. This nonflammable fluid is a powerful cleaner with a low global warming potential. It is used as an alternative to CFC-113, methyl chloroform, hydrochlorofluorocarbons (HCFCs) and perfluorocarbons (PFCs) in many critical cleaning, drying, carrier fluid and…
