AURON CL-54 – HCFO cleaning agent for precision cleaning

From removing stubborn machining oils to cleaning sensitive electronic assemblies – AURON CL-54 was developed for industrial cleaning processes where process reliability, material compatibility, and sustainability are equally important.

With its high solubility (Kb value of 44), a low boiling point of 54 °C, and excellent recoverability via distillation, AURON CL-54 offers a cost-effective alternative to traditional chlorinated or fluorinated solvents. At the same time, the product meets modern environmental requirements with a GWP < 1, an ODP of nearly 0, and a PFAS-free formulation.

Why AURON CL-54?

Maximum cleaning performance

Even challenging contaminants such as cutting oils, pressing oils, silicone oils, greases, or waxes are reliably removed. Thanks to its high solubility, AURON CL-54 is particularly suitable for precision components with complex geometries

Higher productivity

Due to its low boiling point, the solvent evaporates quickly and leaves no residue. This significantly shortens process and drying times, increasing productivity.

• shorter cycle times
• less downtime
• less rework
• clean, dry components immediately after the cleaning process

Sustainable operations

AURON CL-54 was developed to reduce both environmental impact and operating costs.

✔ PFAS-free
✔ GWP < 1
✔ ODP nearly 0
✔ Easy distillation
✔ Low solvent consumption
✔ High process stability
