Techspray engineers PWR-4™ industrial cleaners as ideal nPB replacement

3400-20S_applTechspray®, a manufacturer of precision cleaners for electronics, and industrial and electrical applications, introduces PWR-4™ solvent cleaners. PWR-4 solvents are ideal replacements for n-propyl bromide (nPB) and other toxic industrial solvent because they are safer, non-flammable, and cost effective. PWR-4 quickly blasts off oils, greases, fluxes, silicones, dirt and grime.

PWR-4 is available in aerosol or bulk for vapor-degreasing, ultrasonic and immersion cleaning. It is engineered to remain stable and effective over thousands of cycles in vapor degreasing equipment. PWR-4 is stabilized and safe for metals such as aluminum, magnesium, titanium, and brass.

PWR-4_groupPWR-4 Flux Remover (part #3401) quickly cleans the most difficult baked-on R, RMA & no-clean fluxes from electronic assemblies. PWR-4™ Industrial Maintenance Cleaner (#3400) quickly cleans the most difficult greases and oils from electronics, relays, and motors.

n-Propyl Bromide (nPB), Trichloroethylene (TCE), and Perchloroethylene (Perc) are three examples of harmful chemicals that are commonly used in industrial applications because they are non-flammable, have high solvency, and are relatively inexpensive. Because of safety concerns, they 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 for nPB, 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.

Paul Blair, Techspray Marketing Director stated, “PWR-4 provides all the cleaning power of nPB and other industrial solvents, but without the health risks.”
