Techspray PWR-4 Maintenance Cleaner
Techspray introduced PWR-4 Maintenance Cleaner, a high performance cleaning solvent engineered to be a safer alternative to common industrial solvents like n-propyl bromide (nPB).
PWR-4 Maintenance Cleaner quickly dissolves oils, greases, fluxes, silicones, dirt and grime. Fast evaporation and high dielectric strength allows work to be completed quickly, minimizing equipment downtime.
PWR-4 is designed for wiping down parts and machines, for use in ultra-sonic cleaning equipment, and vapor-degreaser equipment. It is available in gallon (part #3400-G), 5-gallon (#3400-5G), and 55-gallon drums (#3400-54G).
PWR-4 is ideal where a safer, non-flammable, and cost effective cleaner is required. It is much safer than the four common industrial solvents: nPB, trichloroethylene (TCE), perchloroethylene (perc), and methylene chloride, but with similar cleaning performance.
Because of safety concerns, nPB, TCE, Perc, and Methylene Chloride have a great number of regional and federal restrictions. For example, in a field study by the National Institute for Occupational Safety and Health (NIOSH), they recommend replacing nPB in aerospace vapor-degreasing.

PWR-4 Maintenance Cleaner has no impact on the ozone layer, so it can be used to replace AK225-based solvents, which were phased-out by the EPA starting in 2015.
