Kersol Stabilized nPB (N Propyl Bromide)
Degreasing and Cleaning Solvent
Kersol Stabilized nPB (N-Propyl Bromide) is a degreasing and cleaning solvent specially formulated to remove contaminants such as oils, greases, adhesives, resins, and flux residues.
Kersol nPB has physical properties and solvency characteristics that are similar to chlorinated solvents such as 1,1,1-trichloroethane and trichloroethylene.
Its use as a vapor degreasing solvent is suitable for removing a wide variety of soils. It can also be used in immersion cleaning applications.
Kersol nPB is a direct replacement for 1,1,1-trichloroethane, HCFC-141b, HCFC-225, hydro fluorocarbons, and methylene chloride in vapor degreasers.
Kersol Stabilized nPB (N-Propyl Bromide) is designed for use in a vapor degreasing process. Kersol nPB can be used in existing vapor degreasing equipment (batch or inline), but emission control retrofits may be useful in reducing vapor losses.
If existing equipment is utilized, it is necessary to adjust temperature control settings.

Kersol Stabilized nPB (N-Propyl Bromide) was tested for compatibility with metals according to MILT- 81533A.
In this test, metal coupons were submerged halfway in the refluxing fluid for twenty-four hours.
The following metals showed no signs of corrosion.
Aluminum, Brass, Carbon Steel 1010, Copper, Inconel, Monel, Nickel, 316 Stainless Steel, Titanium and Zinc.
The compatibility of aluminum with Stabilized n Propyl Bromide was further tested by scratching an aluminum coupon beneath the surface of the solvent. Several hours elapsed before signs of corrosion were noticed.
In contrast, when 1,1,1 -trichlorethane is subjected to the same test, corrosion can be seen immediately.
The table on the following page details the results of compatibility testing with selected plastic and elastomeric materials.
The table is intended only as a general guide.
Kersol recommends that you test compatibility with the particular materials in question under your actual use conditions.
