Calling all Trike/PERC/MECL users!
The sunset date for Trichoroethylene (Trike or TCE) as a cleaning solvent has been and gone but many are still using Trike and are looking to find an alternative solution. Those with Type IV or V cleaning systems were granted blanket authorisation to continue using Trike, subject to strict conditions, which may soon be under review.
Some will have switched to alternative chemistries such as Perchloroethylene (PERC) and Methylene Chloride (MECL) but these should also be viewed with extreme caution as strict DEFRA (Department for Environment, Food and Rural Affairs) rules apply to them, and health and safety considerations need to weighed carefully.
Fraser Technologies recommends Opteon™ SF80 by Chemours – a powerful, safe and eco-friendly component cleaning agent. Its remarkable characteristics make it the ideal drop-in replacement for restricted chlorinated solvents such as Trichloroethylene, perchloroethylene (PERC), Methylene Chloride (MECL), high GWP fluorinated solvents HFC and HFEs and nProply bromide (nPB) – in the majority of applications.
With no compromise on cleaning power, Opteon™ SF79 was first choice for many manufacturers in the aerospace and automotive industries for replacing Trike in 2016 with a safer, compliant solvent. Chemours has since launched SF80, with an even lower GWP and this has now become the preferred product for all old generation solvent replacements.
Here’s why – the solvent comparison table below demonstrates that SF80 has the lowest GWP* of any new generation solvent (<2.5 compared to old generation solvents which has GWP of over 11,000), combined with lower Risk Phrase and high cleaning power 99kb. And, looking forward, there will be no EU 2014 F-gas regulation restrictions looming.
* GWP (Global Warming Potential) was developed to allow comparison of the global warming impacts of different gases. Specifically it measures how much energy the emission of a gas will absorb, relative to CO2 over a specified period. The larger the GWP the more that a given gas warms the Earth compared to CO2. 1kg of CO2 = GWP of 1.

Part of the new Opteon™ New Generation speciality fluids by Chemours™, SF80™ is:
- An easy drop-in alternative to restricted solvents
- Cost-effective in use – energy-saving and inherently stable, needing no acid testing, stabiliser maintenance, solvent monitoring or vapour extraction
- Ultra Eco-friendly, with the lowest global warming potential (GWP) on the market, recyclable and re-usable
- Non-flammable and safe in use, with a safe exposure limit – TLV – of 202ppm (parts per million) – the limit for nPB is 2000 times lower at 0.1ppm
- High performing, with 99kb cleaning power, comparable to older solvents and over twice that of HFE
- SMI-tested for aero industry materials specification – conforms to BAC 5750, tested in accordance with ARP 1755B, ASTM F1110, ASTM F 519 (1A.1) and ASTM F945-06 (A)
F-gas restrictions & new regulations
F-gases are much more prevalent in the cleaning industry than buyers are aware, often present in old generation solvents used across a wide range of industry sectors. The high Global Warming Potential of these gases means their use is severely restricted throughout Europe, with usage in certain applications a criminal offence.
Countdown to nPB ban
The sunset date for the use of nPB is fast approaching – 4 July 2020! There will be no exceptions under this legislation, and the date for requesting special authorisation to continue using nPB has gone. Time is of the essence here, as the process of switching chemistries and/or cleaning equipment can take months – so get ahead of the competition.
