PRE-TREATMENT, SURFACE PREPARATION, DEGREASING & CLEANING Speciality cleaning fluids in the driving seat

The automotive industry is evolving rapidly to meet environmental and performance standards around the world. At Fraser Technologies, we work with many leading automotive manufacturers to ensure that their systems are maximising efficiency.

One of the key methods for providing this efficiency is utilising Chemours

Opteon™ Specialty Fluids (SF), which offer numerous benefits. They are extremely safe, low-cost in use, and offer an ultra-low carbon footprint while delivering exceptional performance. They are suitable for applications in the automotive industry, including:

Cleaning and carrier fluids for fluorinated lubricants and grease

Carrier fluid for adhesives

Cleaning engine and gearbox components

Bonding and cleaning of composites

Cleaning and cooling of EV battery

Cleaning and lubrication of bearings

Hydraulic system cleaning

The two key applications we recommend most frequently are heat transfer carrier fluids, and cleaning.

Heat transfer and carrier fluids

The fastest and most effective way to cool a battery is direct fluid contact with a dielectric fluid, known as immersion. These fluids can either be used as single phase, pumped much like current heat exchanger systems, or employed as a simple two-phase system with condensing and evaporation. Immersion cooling using SF answers the need for a safe battery; it provides the most efficient heat transfer using non-conductive and non-flammable fluids while also enhancing safety.

Alternative liquids, such as PAO oils and silicone-based fluids are potential candidates, but the Opteon™ SF products provide up to 30% higher heat removal performance in a single-phase system. This offers a much more efficient heat transfer process as the coolant gets closer to the heart of the heat. Additionally, by using two-phased immersion cooling systems, the latent heat during phase change is significantly larger than liquid thermal conductivity and thus provides a more uniform temperature across the entire battery pack. The Opteon™ SF range has been specifically developed with performance and environmental sustainability in mind. The Opteon™ product portfolio includes heat transfer fluids for many different applications and temperatures ranging from -90°C to 250°C. Fluids are non-flammable, offer excellent stability and provide superior heat removal in dielectric applications, with an environmentally friendly footprint.

Cleaning

When it comes to cleaning potential, Opteon™ SF80 specialty fluid is designed to meet the high solvency needs in the industrial cleaning market. The commercial uses of this specialty fluid include oil and grease removal, precision cleaning, high solvency defluxing, silicone removal, vapour degreasing and cold cleaning. Significant advancements have been made in industrial solvent cleaning, making specialty fluids a viable, safe and cost-effective option. They use eco-friendly chemistries, and are an effective alternative to older, hazardous solvents and those containing F-gases that have now been banned or restricted. And Opteon™ SF80 has a GWP of <2.5, which is one of the lowest GWP figures on the market for this type of chemistry. Historically, other common F-gas solvents have had GWP figures of up to 11,000. (see graph to the right). The Chemours™ range of safe, environmentally friendly solvents has become widely accepted as best in class and is approved for use in a large range of standard cleaning systems. If considering a new solution for oil and grease removal; precision cleaning; high solvency defluxing; silicone removal; vapour degreasing; or cold cleaning, Fraser Technologies can support the right products to deliver cleaning requirements.
