Which Isopar to Use – C, G, or M?

The Isopar series of chemicals formulated by ExxonMobil are synthetic isoparaffin solvents. The solvents have high purity that is achieved through a distinct selection of raw materials and complex manufacturing processes. Each solvent is designed for specific applications, based on the specific properties each has.

Applications of Isopar Solvents

Isopar C – Due to its properties, C is designed for applications including:

  • Adhesives
  • Chemical process solvents
  • Consumer products
  • High octane fuel

With the lowest initial boiling point of the Isopar solvents, C’s minimum initial boiling point is 96 °C. It also has the lowest minimum specific gravity of the solvents at 0.694. The aniline point can range from 77 to 80°C.

Isopar G – As a high purity isoparaffinic hydrocarbon fluid, G can be used in the following applications:

  • Household products
  • Aerosols
  • Cleaning
  • Metalworking
  • Coatings
  • Cosmetic products
  • Liquid toners

The notable properties that make G ideal for these applications include:

  1. Minimum Flashpoint of 40°C
  2. Dielectric constant at 25°C between 1.995 and 2.006
  3. Specific gravity between 0.743 and 0.755
  4. Minimum initial boiling point of 155°C
  5. Aniline point ranges from 79 to 85°C

Isopar M – Similar to G, M can be used for all the applications listed under G, except liquid toners. This solvent is not a suitable solvent for liquid toners because the properties of M are slightly different from G. Notable properties of M include:

  • Specific gravity between 0.784 and 0.796
  • Viscosity at 40°C between 2.2 and 3.1 cSt
  • Minimum initial boiling point of 218°C
  • Aniline point ranges from 87 to 96°C

With the small differences in the properties of the solvents, each solvent is better suited for different applications. Although G and M have many applications in common, one may be more beneficial depending on the specific job.
