Boeing BAC5408 Approved ADVANCED Solvent

THE FUTURE OF SOLVENT CLEANING

AeroTron-AV-5408 has been approved by Boeing for use in vapor degreasing in the 5408 Specification. For companies that can no longer use traditional chlorinated solvents like TCE, Methylene Chloride or Perc and need to move away from 1-Bromopropaine (nPB), AeroTron-AV-5408 is approved for use as an alternative. AeroTron-AV-5408 is specially formulated for metal, plastic and elastomer compatibility in aerospace cleaning and can be used to clean titanium.
