AeroTron™ is a Direct nPB Replacement

AeroTron™ cleans as effectively as nPB.

AeroTron™ is as effective as nPB in cleaning a variety of contaminants from fabricating oils to abrasives. AeroTron™ is a high performance parts cleaning solvent that is an environmentally sound, direct nPB replacement solvent. AeroTron™ is a non-chlorinated, non-flammable, affordable vapor degreasing solvent that is ideal for replacing n Propyl Bromide. Use AeroTron™ instead of nPB when you want to have a solvent parts cleaner and vapor degreasing solvent that works like nPB without the detrimental health and safety impacts.

AeroTron technical data sheet


Excellent Health & Safety Profile as Compared to nPB

AeroTron™ Benefits are Significant:
  • EXCELLENT WORK PLACE RECOMMENDATION - Very favorable workplace recommendation of 200ppm TLV-TWA for AeroTron™ compared to 10ppm for nPB.
  • NO TOXICITY - n Propyl Bromide is a suspected human carcinogen based on recent test results from the NTP and n Propyl Bromide has reproductive toxicity. AeroTron's components do not have these characteristics.
  • NO HYDROLYSIS REACTION - n Propyl Bromide is vulnerable to creating acid in the presence of water and is stabilized against this. The amount of stabilizer in nPB needs to be tested frequently to make sure there are sufficient stabilizers in the solution. AeroTron™ is stable in the presence of water.
  • BETTER PERFORMANCE - similar to nPB in that:
    • No residue & fast evaporating
    • Azeotropic formulation
    • Not NESHAP regulated
    • Does not require special reporting
    • Ships via common carrier
    • Can be used in your current vapor degreasing equipment

Works Like nPB Without the Detrimental H&S Impacts


AeroTron™ can be used as effectively as nPB in asphalt extraction.

Because AeroTron™ is non-flammable, it is suitable for use in any asphalt extraction process. It is very fast acting and removes the bitumen / tar easily from samples.
