The more you know about metalworking formulations, the clearer the choice becomes.
Gone are the days when you could choose a hydrocarbon fluid simply because of its solvency power and cost.
Today your business decisions are much more complex combining:
  • Product performance
  • Protection of employee and user health
  • Environmental responsibilities
Somentor™, Exxsol™ D and Isopar™ hydrocarbon fluids are a leading choice for cooling and lubrication fluids used in metalworking processes. Wide product portfolio enables tailor-made formulations to meet customers’ specific needs.

What application are you looking for?

Aluminum rolling

ExxonMobil’s Somentor™ hydrocarbon fluids provide good safety and performance required by the aluminum industry. It has been widely used for more than three decades. Somentor™ hydrocarbon fluids are specially designed for the aluminum-rolling industry, offering:
  • Improved annealing properties that reduce the potential of production rejects
  • FDA compliance for use in the production of food-packaging foils and sheets1
  • Low odor to ensure good working environment

1 FDA 21 chapter 178.3910 (a) and (b) regulations. This webpage is not the official source for regulatory claims. For regulatory compliance statements, please contact Customer Service

Metal forming

In metal forming processes such as stamping, punching, rolling or drawing, Somentor, Exxsol D and Isopar fluids offer:
  • High degrees of quality and consistency for reliable forming fluid formulation performance
  • Narrow boiling range for optimized formulations and drying times
  • Choice of boiling ranges and flash points allows for tailored fluid formulations (select from wide range of evaporation rates & viscosities)
    • Exxsol D: lower boiling point, faster evaporation rate
    • Somentor: medium to high viscosity with higher flash point
    • Isopar: narrower boiling range
  • Low aromatics

Rust prevention

Exxsol D and Isopar fluids give formulators of rust prevention oils optimum control over product performance and a high level of safety and comfort for their employees and customers. Exxsol D and Isopar fluids offer:
  • A balance of tailored drying times, viscosity, lubrication and safe operating conditions
  • Good spreading and wetting properties
  • Low aromatic content resulting in low odor, lower toxicity
Odor intensity graph
The odor intensity result is expressed in parts per million (ppm) of n-butanol. A larger value of butanol concentration means a stronger odor.

Improved comfort

Lower dilution ratio stands for lower odor.

Detection threshold
Recognition threshold
The detection threshold (DT) is an estimate of the number of dilutions needed to make the actual odorous air sample “non-detectable”.
The recognition threshold (RT) is also a “dilution ratio” and represents the number of dilutions needed to make the odor sample “faintly recognizable".

Evaporable oils

Evaporable oils typically provide a thin lubricant layer on a part during processing that swiftly evaporates afterward. For fast-drying evaporable formulations, Exxsol D fluids offer:
  • Simplified operations, no secondary cleaning step is necessary
  • Very low viscosity formulations for fast and uniform spreading
For odorless evaporable forming oils, Isopar fluids offer:
  • Enable the formulation of outstanding self- evaporable oils
  • Comply with selected food contact applications
  • Result in fast and uniform spreading of the formulated oil on metal parts

Electro discharge machining (EDM)

EDM is a sophisticated process to shape complex and highly defined components. Exxsol D and Isopar fluids help control equipment temperature during electro discharge while quickly
removing residual metallic pieces.
Advantages of Exxsol D and Isopar fluids:
  • Low electric conductivity for spark control
  • High flash points for great safety margins and applicability in higher-power sparking applications
  • High thermal and chemical stability for long fluid life, better fluid integrity, fluid reuse and performance
