Klenasol NPB is a lower boiling point solvent that is particularly useful in cleaning metals and
electronic components because of its high solvency for oils, greases and fluxes. Klenasol NPB has no
flash point and has physical characteristics and performance similar to trichloroethylene, so
equipment changes and conversion costs can be kept to a minimum.
