Powerful, Non-Flammable & Cost Effective Cleaner

PWR-4™ solvent cleaners are ideal where a safer, non-flammable, and cost effective cleaner is required. This innovative solvent is much safer than the four most common industrial solvents: TCE, nPB, Perc and Methylene Chloride and quickly blasts off oils, greases, fluxes, silicones, dirt and grime.

  • Ideal replacement for n-propyl bromide (nPB) and other toxic industrial solvents
  • Available in aerosol or bulk for vapor-degreasing, ultrasonic and immersion cleaning
  • PWR-4™ Maintenance Cleaner for heavy-duty degreasing and contact cleaning, PWR-4™ Flux Remover for PCB cleaning

Safer Replacements For Toxic Industrial Solvents


n-Propyl Bromide (nPB), Trichloroethylene (TCE), and Perchloroethylene (Perc) are three examples of harmful chemicals that are commonly used in aerosol cleaners in industrial applications.  These chemicals are commonly used as cleaning solvents because they are non-flammable, have high solvency, and are relatively inexpensive.

Because of safety concerns, these solvents are under close scrutiny by OSHA, EPA, and local agencies. For  example,  The American Conference of Governmental Industrial Hygienists (ACGIH) recommends a 10 ppm  time-weighted average threshold limit, but has proposed a lower 0.1 ppm (ACGIH 2013). That’s because nPB  is a suspected human carcinogen, and has shown to negative impact neurological and reproductive  functioning.

Techspray offers effective replacements for these toxic solvents. PWR-4® High Performance Solvents provides all the cleaning power of nPB and other industrial solvents, but without the health risks.
