AeroTron®-100 is a Direct nPB Replacement
AeroTron®-100 cleans as effectively as nPB in vapor degreasing and cold wipe.
AeroTron®-100 is as effective as nPB in cleaning a variety of contaminants from fabricating oils to abrasives in vapor degreasing and cold wipe cleaning. AeroTron®-100 is a high performance parts cleaning solvent that is an environmentally sound, direct nPB replacement solvent. AeroTron®-100 is a non-chlorinated, non-flammable, affordable vapor degreasing solvent that is ideal for replacing n Propyl Bromide.
Use AeroTron®-100 vapor degreasing solvent instead of nPB when you want to have a solvent parts cleaner that works like nPB without the detrimental health and safety impacts.
Excellent for Vapor & Ultrasonic Cleaning
- No special equipment modifications required for vapor degreasing
- Health & safety upgrade from nPB
- Use as a direct, drop-in nPB replacement in your vapor degreaser
- Easy to switch over to AeroTron®-100
AeroTron®-100 Means Improved Health & Safety Profile - 200PPM
Excellent Health & Safety Profile as Compared to nPB
AeroTron®-100 Benefits are Significant:
- EXCELLENT WORK PLACE RECOMMENDATION - Very favorable workplace recommendation of 200ppm 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.
- 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
Aerospace
Use AeroTron®-100 vapor degreasing solvent 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.
Electronics
Removal of flux and flux residues, polar and non-polar contamination, cleaning of electrical assemblies and fingerprints.
Optics
Cleaning of potting and masking waxes and fingerprints.
Metal Fabrication & Coating
Cleaning prior to coating, welding, brazing, or adhesive bonding.
Use 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.

Essentially:
- DRAIN: the vapor degreaser sumps (using solvent transfer pump), spray reserve tank, water separator and filtration tank of old solvent.
- SET: the temperature control settings for 109F (43C)
- FILL: the boil sump and immersion sump with AeroTron®-100
Use AeroTron®-100 for Asphalt Extraction
AeroTron®-100 can be used as effectively as nPB in asphalt extraction.
Because AeroTron®-100 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.
