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

PWR-4™ Industrial Maintenance Cleaner Blasts away oil and contaminants off of contacts, printed circuit boards, barcode instruments, switch boxes, gear boxes, and electronic motor controllers. Grease and oil flow right off, reducing the time and materials needed to scrub off stubborn soils.

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 greases and oils from electronics, relays, and motors. It is engineered to remain stable and effective over thousands of cycles in vapor degreasing equipment.

Removes oils, greases, silicones, refrigerant oils, fluxes, adhesives and other common industrial contaminants. Used for cleaning medical instruments, implants and other devices including orthopedic implants, monitoring devices, oxygen and gas lines. This solvent can be used as a carrier fluid like for silicone-based lubricant coatings.

Nonflammable
Much safer than most common industrial solvents — TCE, nPB, Perc & Methylene Chloride
Powerful cleaner — Ideal for degreasing and contact cleaning
Available in aerosol or bulk for vapor-degreasing, ultrasonic and immersion cleaning
Rapid evaporation
Non-ozone depleting
Cleaning applications: electronics, relays, switches & breakers, transformers, and electric motors and generators
NSF registered K1 and K2

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

How do you know the safe exposure limit of a degreaser, contact cleaner, or flux remover?

The personal hazard associated with a solvent is often defined using Threshold Limit Value (TLV), which is the recommended average exposure in an 8-hour day, 40 hour work week. The lower the TLV of a particular substance, the less a worker can be exposed to without harmful effects. TLV is stated on the SDS of chemical products, in additional to recommended personal protection equipment (or PPE). The threshold limit value of a solvent is generally set by the American Conference of Governmental Industrial Hygienists (ACGIH). The unit of measure is Parts Per Million (PPM).

How do you use an aerosol cleaner?

Hold object to be cleaned in vertical position. Pull trigger gently to control solvent flow rate. Spray from top to bottom, allowing the liquid to flush away contaminants.

There are a number of regulations prohibiting the use of chlorinated solvents. Should I be concerned with Trans, which is used in many of your nonflammable cleaners?

No, it should not be a concern. Many of Techspray's nonflammable solvents (e.g. G3, Precision-V, PWR-4) contain 1,2-trans-dichloroethylene (Trans, CAS# 156-60-5), which has caused confusion. The regulations controlling chlorinated solvents do not generally pertain to Trans. The following are the reasons: Many are confused with “chloro” substances due to the NESHAP requirements. The big 3 chlorinated substances are Perchloroethylene (Perc), Trichloroethylene (TCE), and methylene chloride. The association of those with all chlorinated substances is not valid. NESHAP requirements only refer to restrictions of emissions of hazardous air pollutants (HAP). Of the nearly 200 substances listed as HAP’s, Trans is not on that list. Reference the following link: https://www.epa.gov/haps/initial-list-hazardous-air-pollutants-modifications. Trans has the same exposure limit (per ACGIH) time-weighted average (TWA) as 2-propanol (IPA) -- 200 ppm. In contrast, n-Propyl Bromide (nPB) is commonly used in vapor degreasers, with TWA established by ACGIH of 10 ppm. It has been proposed to be reduced to 0.1 ppm. nPB is also listed on various carcinogen lists, notably Prop 65.

What spigot or spout do you recommend for your metal 5-gallon and 55-gallon drums?

Metal 5-gallon containers come with a flexible pop-out spout for easy pouring. 55-gallon drums are compatible with standard 2" spouts.

How do I properly dispose of an aerosol can after it is empty?

It may be different state-by-state, so contact your state environmental agency for regional specific regulations. For a general guideline, here is the process according to EPA hazardous waste regulations 40CFR. The can has to be brought to or approach atmospheric pressure to render the can empty. Puncturing is not required, only that it “approach atmospheric pressure”, i.e. empty the can contents until it’s no longer pressurized. This insures that as much contents as is reasonably possible are out of the can. It is then considered “RCRA-empty”. At that point it can be handled as any other waste metal container, generally as scrap metal under the recycling rules. Note that the can is still considered a solid waste at this point (not necessarily hazardous waste).

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.

Are there degreasers that are more toxic than others?

N-Propyl Bromide (nPB), Trichloroethylene (TCE) and Perchloroethylene (Perc) are highly toxic chemicals commonly used in degreasers to provide cleaning performance in a nonflammable formula. There are documented court cases where workers suffered major health effects when exposed to high levels of these chemicals. Workers reported headaches, dizziness, and even loss of full body control. There are also possible links to reproductive problems and cancer. All of this has caused maintenance facilities to reconsider their solvent choices, especially with manual cleaning when exposure tends to be higher.

Should I worry about plastic packaging and components and rubber seals when degreasing?

Rigid plastics like ABS, polycarbonate (trade name Lexan), and acrylic materials like Plexiglass can be very sensitive to harsh solvents like toluene, xylene, and acetone. Alcohol and hydrocarbon based solvents tend to be better on sensitive plastics. Rubber, silicone or other seals or gaskets made of elastomeric (soft) materials can have a tendency to swell or shrink with exposure to harsh solvents. After the solvent flashes off, they may spring back to their original dimensions, or be permanently changed, impacting the effectiveness of the seal. Polyester or Teflon based gasketing materials are less prone to this type of damage from harsh solvents.
