AeroTron™-100 is a Direct nPB Replacement

AeroTron™-100 cleans as effectively as nPB in vapor degreasing and cold wipe.

AeroTron™-100 is a direct nPB replacement for cleaning a variety of contaminants from fabricating oils to abrasives in vapor degreasing and cold wipe cleaning. AeroTron™-100 is an alternative to nPB that provides a high performance parts cleaning solvent that is an environmentally sound, direct nPB replacement solvent with an excellent Health & Safety profile. AeroTron™-100 is a non-flammable, affordable, fluorinated vapor degreasing solvent that is ideal for replacing n Propyl Bromide with no boosting or bath testing required.

Use AeroTron™-100 vapor degreasing solvent to replace n propyl bromide (a.k.a. nPB) when you want to have a solvent parts cleaner that works like nPB without the detrimental health and safety impacts.

AeroTron<sup>®</sup>-100 vapor degreasing solvent performance

Excellent for Vapor & Ultrasonic Cleaning

  • No special equipment modifications required for vapor degreasing
  • Health & safety upgrade from n propyl bromide
  • Use as a direct nPB replacement in your vapor degreaser
  • Easy to switch over to AeroTron™-100

AeroTron™-100 Means Improved Health & Safety Profile - 150 PPM

Excellent Health & Safety Profile Makes AeroTron™ an Excellent nPB Alternative

AeroTron™-100 Benefits are Significant:
  • EXCELLENT WORKPLACE RECOMMENDATION - Very favorable workplace recommendation of 150 ppm TLV-TWA for AeroTron™-100 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™-100's components do not have these characteristics, making it a safer replacement for nPB.
  • 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™-100 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

Typical Applications by Industry


Use AeroTron™-100 vapor degreasing solvent as an nPB alternative for the removal of greases, oils, silicone, masking waxes, masking lacquers, NDT dye penetrants, drawing lubricants, coolant residues and adhesives. Also ultrasonic vapor degreasing for removal of metal fines, polishing abrasives and blasting media.


AeroTron™-100 easily removes flux and flux residues, polar and non-polar contamination, and cleans electrical assemblies and fingerprints as effectively as nPB.


Cleaning of potting and masking waxes and fingerprints.

Metal Fabrication & Coating

Cleaning prior to coating, welding, brazing, or adhesive bonding.
Use AeroTron™-100 to replace n propyl bromide for vapor degreasing, ultrasonic cleaning and cold wipe cleaning processes to achieve near residue free surface cleanliness prior to plating, painting, physical vapor deposition (PVD) or robotic welding, vacuum brazing, or adhesive bonding of metal parts.
