The new XBB cutting fluid technology from Castrol, however, now maintains constant pH levels and stable conditions for longer than other standard cutting fluids.

Metalworking fluids can suffer from bacterial growth and contamination, resulting in a shortened service life. This leads to pH depletion, unpleasant odours, unstable emulsion and poor performance. Additives and biocides have been the way to control this up to now.

The new XBB cutting fluid technology from Castrol, however, now maintains constant pH levels and stable conditions for longer than other standard cutting fluids. As the company stresses, this has been proven in lab tests and seen in real production conditions. This enables cost savings in top-ups, biocide, and frequent fluid changes, without harmful chemicals.

Castrol Hysol SL 36 XBB
Castrol Hysol SL 36 XBB is optimised for metalworking with ferrous alloys (cast iron and low alloyed steel), but has also been used successfully with aluminium. It’s suitable for large central systems and single sump machines. This product is also designed to reduce foaming in soft water environments.

Its dual-buffer technology resists pH changes caused by bacterial build-up in your cutting fluid, meaning it performs better for longer than standard cutting fluids*. Castrol Hysol SL 36 XBB is also both boron- and biocide-free, meaning your working environment is not only more efficient and more competitive, but also a far safer place to be.

Take control of pH
Castrol Hysol SL 36 XBB is a cutting fluid that is shown to perform better for longer, thanks to a formula that is more resistant to changes in pH than conventional alternatives*. Your production environment is interrupted less frequently by fluid performance and corrosion becomes less of an issue and it becomes easier to meet your production goals while keeping costs down.

Fewer top-ups
The boron and biocide-free Castrol Hysol SL 36 XBB improves operating conditions and your health and safety profile and results in fewer interventions and less management of cutting fluids.

Where other coolants need topping up with service additives to keep working well, cutting fluids with Castrol’s XBB technology have been proven to perform without these measures for longer than conventional alternatives**.

The fluid’s excellent emulsion stability properties increase production time.

Reduce corrosion

Castrol Hysol SL 36 XBB’s carefully engineered formula helps to protect against corrosion even at lower concentrations, resulting in less machine maintenance, lower costs and fewer rejected products.

The new fluids are available in two variants.

* Based on titrating 7 fluids until a pH 7 is reached.
** Proven in lab tests and seen in real production conditions.

Castrol Alusol SL 61 XBB
Castrol Alusol SL 61 XBB is ideal for multipurpose machining of aluminium alloys through to low-medium alloyed steel and is suitable for both large central systems and single sump machines. It is designed to work well in soft and hard water conditions alike.

Castrol’s unique boron and biocide-free formula has been proven to maintain pH at a constant level (neutralising up to 44% more acidic material*), ensuring Alusol SL 61 XBB performs better for longer.

It is ideal for demanding aluminium work, including low-silicon applications, with the high lubricity keeping the cutting edge clean, reducing downtime and improving surface quality. With Castrol Alusol SL 61 XBB, not only can you achieve great results at lower concentrations you can also make big savings.

Ultimately you have less maintenance, less expense and a safer working environment, without ever compromising on performance.

Perform better, for longer
Castrol Alusol SL 61 XBB performs better for longer than standard cutting fluids*, thanks to a pioneering formulation designed to be more resistant to changes in pH caused by microbiological build-up. This means fewer additive top-ups, better results and more efficient production at a lower cost.

Give productivity a boost
The big benefit of extended fluid life is less downtime and fewer interventions. Many cutting fluids need topping up with additives to maintain fluid condition. Castrol’s Alusol SL 61 XBB has been proven to perform continuously without these measures for longer than conventional alternatives**.

This not only gives you constant working conditions, so you can consistently achieve good results, but also safeguards the health and safety of your workers.

Experience precision performance
Because Castrol Alusol SL 61 XBB performs for longer, it preserves the cutting edge and helps to prevent build-up on the tool and part, resulting in a cleaner, more accurate finish. Its excellent lubricating properties prevent swarf build-up and pH control reduces acid corrosion. Ultimately, this results in lower scrappage rates and lower tooling costs and improves production quality.

* Based on titrating 10 fluids until a pH of 8.5 is reached.
** Proven in lab tests and seen in real production conditions.
