PWR-4... The Safer, Powerful n-Propyl Bromide (nPB) Replacement

PWR-4™ Flux Remover is ideal where a safer, nonflammable, 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 cleans the most difficult baked-on R, RMA & no-clean fluxes from electronic assemblies. It is engineered to remain stable and effective over thousands of cycles in vapor degreasing equipment.

  • Nonflammable
  • Much safer than most common industrial solvents — TCE, nPB, Perc & Methylene Chloride
  • Powerful cleaner - Effective on R, RMA & no-clean fluxes
  • Available in bulk for vapor-degreasing, ultra-sonic and immersion cleaning
  • Rapid evaporation
  • Non-ozone depleting

Vapor Degreaser Setting Guidelines

  • Boiling point – 118°F / 48°C
  • Boil sump temp set – 127°F / 53°C  
  • High solvent temp set – 136°F / 58°C
  • Refrigerant high temp set – 109°F / 43°C

Note: As with all vapor degreaser equipment and processes, observe all safety precautions, guidelines and operating rules associated with these units.  Failure to do so may put operations personnel at risk.  Avoid excessive vapor losses, loss of refrigeration, excessive boil sump heat, etc.  Make sure all equipment is operated in accordance with the manufacturer’s guidelines and instructions.  If in doubt, contact your manufacturer immediately.

FAQ's

Are PWR-4 cleaners good replacements for n-propyl bromide (nPB)?

Yes, PWR-4 high performance solvent cleaners are nonflammable, powerful cleaners like nPB, safer than nPB, and are also economically priced.


How do I figure out the shelf life of a product?

The shelf life of a product can be found on either the technical data sheet (TDS), available on the product page, or by looking on the certificate on conformance (COC). The COC can be downloaded by going to https://www.techspray.com/coc. Once you have the shelf life, you will need to add it to the manufacture date for a use-by date. The manufacture date can be identified by the batch number. The batch code used on most of our products are manufacture dates in the Julian Date format. The format is YYDDD, where YY = year, DDD = day. For example, 19200 translates to the 200th day of 2019, or July 19, 2019. This webpage explains and provides charts to help interpret our batch numbers: https://www.techspray.com/batch-codes.
