Description
Outstanding solvency

KB value 70, higher than HCFC-141b (56) and HCFC-225 (31), for thorough removal of oils and grease

Fast drying

39 °C boiling point, so cleaned parts are ready to use right away

Non-flammable

No flash point, low odour and low toxicity

Environmentally sound

ODP 0, not an ozone-depleting substance, and low GWP

Low maintenance

Stable azeotropic-like blend, no stabiliser top-ups, no surfactants needed, residue-free

Works in existing equipment

Runs in most existing vapor degreasers with little or no modification, and can be recovered and reused to cut costs

ORAFON FA-374 is a specialty cleaning fluid designed for industrial cleaning that demands high solvency. It is safe, non-flammable, environmentally friendly and low-GWP, which makes it popular for vapor degreasing.

FA-374 is a near-azeotropic mixture with excellent solvency and low surface tension, so it penetrates and removes grease deeply and efficiently. It is easy to use, highly reliable and needs minimal maintenance.

Replaces

  • High-solvency solvents such as trichloroethylene (TCE), n-propyl bromide (nPB), aromatic hydrocarbons, perchloroethylene and dichloromethane
  • Low- to medium-solvency solvents such as HCFC-225, HCFC-141b, PFC, CFC and water-based cleaners

FAQ
What is ORAFON FA-374 used for?
Industrial parts cleaning, such as removing oils and grease, flux and solder paste on circuit boards, silicone, machining oils in precision metalwork, and cleaning optical glass, in both vapor degreasing and cold cleaning.
Can it replace HCFC-141b?
Yes. FA-374 has higher solvency (KB 70 vs 56), zero ODP and low GWP, making it an alternative to HCFC-141b, which is being phased out.
Is it flammable?
It has no flash point and is flame retardant, but use it with good ventilation, wear protective equipment and avoid breathing the vapour.
Which pack sizes are available?
30 kg and 250 kg drums. Contact the ORAFON team for stock and a quotation.
