Klenasol NPB is an alternative solvent for use in surface cleaning and formulating.
Klenasol NPB is a stabilised, n-propyl bromide (nPB) based solvent. It is a low boiling point solvent
(70º C) and is particularly useful in surface cleaning because of its high solvency for oils, greases and
fluxes and can be used in most vapour and ultrasonic degreasers.
Klenasol NPB has no flash point and has physical characteristics and performance similar to
Trichloroethylene and 1,1,1 Trichloroethane, so equipment changes and conversion costs can be kept
to a minimum.
Klenasol NPB can be used for both vapour degreasing and cold cleaning.
As with the chlorinated products, Klenasol NPB can be recycled by Solvents Australia, making its use
more economical and lowering environmental impacts.
